Key Findings

  • 01A 'minimal emergency call mechanism' and a 'clear visual and voice guidance system' were identified as core basic needs.
  • 02The 'minimal emergency call' had the highest overall weight (0.410).
  • 03TRIZ theory effectively resolved conflicts related to functional integration, operational simplicity, and barrier-free space.
  • 04The developed prototype significantly outperformed traditional facility samples in TOPSIS evaluation (Ci = 0.894 vs. 0.167).

Application

Design takeaway

When designing for specific user groups with critical needs, employ a multi-stage modelling process that quantifies user preferences, prioritizes features, and resolves design conflicts to create demonstrably superior solutions.

How to apply

Utilize a similar integrated modelling approach for any design project requiring the analysis of complex user needs and the prioritization of features, especially when dealing with diverse or conflicting requirements.

Project actions

  • 01When defining user needs, consider using a framework like Kano to categorize them (e.g., basic, performance, excitement).
  • 02Explore methods like AHP for weighting the importance of different needs based on expert or user input.
  • 03Investigate TRIZ for systematic problem-solving and identifying innovative solutions to design contradictions.

Method & Evidence

AimHow can an integrated model combining Kano, AHP, TRIZ, and TOPSIS effectively analyze and prioritize the emergency facility needs of older adults to inform the design of community health emergency stations?
MethodIntegrated modelling framework
ProcedureA cross-sectional study collected data from older adults and caregivers via questionnaires and interviews. The Kano model was used to classify needs, AHP to determine weights, TRIZ to resolve design contradictions, and TOPSIS to rank and evaluate the performance of a prototype against traditional facilities.

ContextHealthcare emergency facilities in older adult communities

Variables

IV["User needs (classified by Kano model)","Prioritization weights (from AHP)","Design contradictions (from TRIZ)"]
DV["Ranked clinical priority of needs","Performance of prototype facility","Effectiveness in resolving design contradictions"]
CV["Community type","Demographics of older adults","Types of emergencies considered"]

Strengths & Limitations

Strengths

  • +Comprehensive integration of multiple analytical models.
  • +Quantitative approach to user needs analysis and design evaluation.
  • +Focus on a critical and underserved user group.

Limitations

The complexity of implementing all four models (Kano, AHP, TRIZ, TOPSIS) might be challenging within a typical design project timeline. Data collection and analysis for each stage require significant effort.

Reliability & validity

The reliability of the findings would depend on the consistency of user responses and the objective application of the AHP and TOPSIS algorithms. Validity is supported by the systematic approach to capturing and analyzing user needs and the comparative evaluation of the prototype.

Think critically

How might the weighting and prioritization of needs differ significantly if the study context shifted to a different cultural demographic or a more acute emergency scenario?

Design Principles

"Systematic prioritization and conflict resolution through integrated modelling leads to optimized design outcomes for specialized user needs."

This integrated model provides a robust framework for designers and researchers to move beyond basic user feedback and quantitatively analyze and prioritize diverse needs. It allows for the resolution of design contradictions, leading to more effective and user-centric solutions, particularly for vulnerable populations.
