Introduction

The HCDE Capstone is a 20-week project where senior students collaborate with real industry sponsors to solve complex design challenges. Teams work through the entire design process—from research to final prototype—while managing client relationships and project constraints. Our team partnered with Dispatch to redesign hospital bedside technology systems.

About

Dispatch provides smart bedside tablets for patient-nurse communication, but faces critical hardware challenges.

Dispatch enhances hospital communication by providing interactive bedside tablets, giving patients additional ways to connect with care teams.

However, their current hardware set up creates major operational issues: nurses waste hours on battery replacements, mounting systems are inaccessible to patients with limited mobility, and power failures disrupt communications. These hardware limitations prevent hospitals from fully leveraging this supplementary communication tool.

Planning

We established project planning through client collaboration and comprehensive research on healthcare technology design.

During the planning phase, we worked closely with Dispatch to understand their business constraints and technical requirements. Our research covered medical device usability, universal design principles, and healthcare regulations. We focused specifically on tablet mounting and power management systems, structuring the project into four milestones to guide our process from initial research through final prototype delivery.

Design Question

How might we redesign the bedside tablet system to reduce maintenance burden while ensuring security and patient accessibility?

Field Study

Direct Observation to Understand Environmental Constraints and Hidden Workarounds

On February 28, 2025, our team visited UW Northwest Hospital with coordination from the Dispatch client team. Due to HIPAA restrictions and patient privacy, we focused on empty patient rooms and nursing stations.

Interview

Capturing Healthcare Workers' Perspectives Through Semi-Structured Interview

We conducted in-depth interviews with nurses, unit secretaries, and managers to understand how hardware failures affect clinical workflows. By comparing non-users and Dispatch users, we uncovered emotional stress points and informal workarounds that directly informed our design decisions.

Technical Analysis

Dispatch provides smart bedside tablets for patient-nurse communication, but faces critical hardware challenges.

We analyzed system components and conducted performance tests to identify gaps between advertised capabilities and real-world use. By documenting all hardware elements, we evaluated how the tablet, mount, battery, and accessories functioned as a single integrated system.

Data Research

Working with Alternative Data Under HIPAA Constraints

HIPAA regulations limited direct patient observation and identifiable data collection. We instead analyzed over 70,000 aggregated patient requests from Dispatch to identify usage patterns and prioritize design features.

Competitive Analysis

Benchmarking Healthcare Tablet Mounting Solutions

We reviewed four competing healthcare tablet systems and compared mounting, power, and security approaches. This analysis revealed a gap between affordable cable-based solutions and expensive integrated systems, creating a clear opportunity for our design.

Research findings

Patients need help most when they can’t reach the communication device

Patients perceive call lights and tablets as a single communication channel, and when tablets are out of reach, access to care breaks down for vulnerable users.

Physical Context

Rigid mounts create dead zones as tables shift.

It's tricky because patients can't move it at all, so when their table moves, they might not reach it or see it

Usage Data

Usage data shows that tablets primarily support frequent, low-mobility care needs.

Daily battery management wastes staff time

The current battery system requires constant manual replacement and causes unpredictable outages, diverting staff time and limiting patient access to care.

Physical Context

Nightly manual charging of 35 batteries, each requiring a six-hour cycle, leads to silent failures that take devices offline during low-staffed night shifts.

The first thing I do is go to all rooms to check... even though I changed it, the next day it's already dead..

energy loss

Evidence from Technical Analysis

Testing revealed over 50% energy loss, reducing expected three-day battery life to a single day and creating an unsustainable maintenance burden.

Security Vulnerabilities Undermining System Purpose

Fragmented, component-level security allows tablets and batteries to be easily removed or misused, undermining system reliability and patient access to care.

Physical Context

Security relies on a tablet-specific adhesive cable lock, leaving batteries and cables unprotected and shifting theft prevention to staff rather than design.

We take tablet out for behavioral patients, people have tried to break them, they've tried to steal them.

Registered Nurse A

Evidence form Interview

People often will take the battery and try to take it or plug their own devices into the battery.

Design Ideation

Collaborative Design Decision

We explored multiple mounting concepts and evaluated them with Dispatch through structured trade-off analysis. Based on accessibility, maintenance, safety, and cost considerations, we selected a wired, articulating arm system that improves reach, reduces maintenance, and fits hospital constraints.

Solution

The Complete Solution

We designed a modular bedside tablet system that improves reach, reduces maintenance, and integrates security across all components.

Arm mount with cable organizer

Adjustable aluminum arm that improves reach while managing cables to reduce clutter and tripping hazards.

Secure Tablet Case

Secures power cables to prevent theft and accidental disconnection in shared hospital environments.

Cable Lock

Protective tablet case with an integrated cable joint and patient-facing handle for secure, easy access.

Features

Features Supporting Safe and Reliable Access

The following features work together to ensure continuous, secure, and safe access at the bedside.

Cable Integrated Case

Integrates the charging cable directly into the case to provide continuous power and eliminate daily battery swaps for staff.

Lockable Security Case

Secures the tablet and cable with staff-only access, while a rounded, safety-first design reduces injury risk.

Cable Organizer

Keeps long power cables managed and out of the bedside pathway.

Cable Lock

Anchors the cable to prevent theft and accidental disconnection and trippin hazards.

Outcome

Successfully reducing workload and costs in hospital

We gathered baseline data through interviews with hospital staff and validated our improvements through controlled prototype testing in simulated environments.

85% Time Saved

Daily maintenance reduced from 105 minutes to 10 minutes.

60% Cost Reduction

Under $80 per unit, well below the $200 budget target.

100% Battery-Free

Eliminated all battery swaps with cable power.

50% Simpler Cable

Stakeholder Feedback

Benchmarking Healthcare Tablet Mounting Solutions

We reviewed four competing healthcare tablet systems and compared mounting, power, and security approaches. This analysis revealed a gap between affordable cable-based solutions and expensive integrated systems, creating a clear opportunity for our design.

Key Concerns

Infection Control

The woven texture may harbor bacteria and be difficult to disinfect thoroughly.

Arm Mount Tension

Will the joints maintain proper tension over time, or become too loose or too stiff?

Emergency Situation

The arm mount's bulk could obstruct quick access to patients during emergencies.

Postive Feedback

Handle Design

One-handed adjustment greatly improves accessibility for patients with limited mobility.

Cost Efficiency

$80 per unit is highly scalable compared to $600+ commercial alternatives.

Reflection

If time is allowed…

  • Run a 4-6 week pilot in an actual hospital unit

  • Build a modular system that works with both battery and cable power

  • Design a mount that works with different hospital furniture

  • Modify the system for critical situations

Key Learnings

This project went beyond typical digital design, requiring us to manage multiple stakeholders, healthcare constraints, and end-to-end delivery of a physical hardware system. Leading the process from research to prototype taught me how to navigate real-world project management and adapt under complex constraints.
