Solution Overview

Problem

Modern patient support systems often include user interfaces that communicate operational information, but this information can be unintelligible to inexperienced users, making it difficult for them to correctly position the systems for accurate weight detection or therapeutic air application.

Innovation Solution

A patient support system with a control system and user interface that displays graphical icons indicating the correct positions of components, using color and directional indicators to guide users in positioning the system for accurate weight detection and therapeutic air therapy, and includes sensors to detect obstructions and alert users to adjust the system accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If operational information is displayed to communicate system status, then information communication is improved, but the information becomes unintelligible to inexperienced users

Engineering Contradiction:
Improveinformation communicationVSAvoiduser comprehension
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent uses graphical icons that visually replicate or represent the physical state of system components (e.g., icons showing deck positions, frame levels, component orientations). These visual copies make abstract operational data intelligible to users by presenting it in a familiar, intuitive format that mirrors the actual physical configuration.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs color-coded indicators to convey system status and guidance information. Different colors represent different states (e.g., green for correct position, red for incorrect position) and provide directional guidance, making operational information immediately comprehensible without requiring users to interpret complex data.

Inventive Principle:
Principle #32Color changes

2Measurement precision

If detailed operational information is provided to guide positioning, then positioning accuracy is improved, but the interface complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidinterface complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the user interface into separate functional icons, each representing a specific system component or function. This segmentation allows detailed positioning information to be presented in discrete, manageable units rather than as a complex unified display, reducing perceived interface complexity while maintaining comprehensive guidance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of presenting raw sensor data or complex operational parameters, the patent inverts the approach by displaying simplified visual representations that directly indicate the desired end state (correct positioning). The icons show what the system should look like when properly configured, rather than presenting the raw data that would require interpretation to achieve the same result.

Inventive Principle:
Principle #13The other way round (Inversion)
