Solution Overview

Problem

Existing human body thermal support devices either provide localized heating that restricts movement and contact with the body, or they fail to maintain a uniformly warmed environment, and lack transparency for visual monitoring.

Innovation Solution

A triple-walled structure with closed gas flow circulation, allowing independent temperature control in inner and outer spaces, using a gas flow preparation unit to warm the inner wall while insulating the outer space, and featuring a transparent design with optional privacy layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a thermal support device provides localized heating through contact with the body, then heating effectiveness is improved, but patient movement is restricted and visual monitoring is blocked

Engineering Contradiction:
Improveheating effectivenessVSAvoidpatient movement freedom
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The device divides the thermal support function into two separate zones: a first space for direct body contact heating and a second space for environmental warming. This segmentation allows the heating function to be distributed without requiring complete body coverage, thus maintaining patient movement freedom while providing effective heating through the inner wall facing the patient's body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The intermediate wall acts as a thermal mediator between the outer wall and the inner wall. It receives warmed gas from the second space and transfers heat to the inner wall, which then provides thermal support to the patient's body. This intermediary structure enables heating without direct contact between the heating source and the patient, preserving movement freedom.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If a thermal support device provides localized heating through contact with the body, then heating effectiveness is improved, but transparency for visual monitoring is reduced

Engineering Contradiction:
Improveheating effectivenessVSAvoidvisual monitoring capability
Core Design Contradiction:
TemperatureVSIllumination intensity

Solution Approach 1:

The device segments the thermal support function into two spaces: the first space with a transparent inner wall for visual monitoring, and the second space that can be opaque for privacy. This allows the heating function to be achieved through the transparent inner wall while maintaining visual monitoring capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner wall facing the patient's body is made transparent to allow visual monitoring, while the outer wall can be opaque for privacy. This local differentiation of material properties enables both visual monitoring and thermal support functions to coexist without compromise.

Inventive Principle:
Principle #3Local quality

3Device complexity

If a thermal support device uses open gas circulation, then device complexity is reduced, but temperature control precision deteriorates and energy consumption increases

Engineering Contradiction:
Improvegas circulation system complexityVSAvoidtemperature control precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The gas circulation system is segmented into two independent loops: a first closed loop for the first space and a second closed loop for the second space. This segmentation allows independent temperature control in each space, improving temperature control precision while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the gas circulation mode from open to closed loop, which fundamentally alters the temperature control characteristics. The closed loop enables precise temperature control by recirculating and reconditioning the gas, maintaining consistent temperature parameters without continuous energy input.

Inventive Principle:
Principle #35Parameter changes

4Device complexity

If a thermal support device uses open gas circulation, then device complexity is reduced, but energy consumption increases

Engineering Contradiction:
Improvegas circulation system complexityVSAvoidenergy consumption
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The closed gas circulation system recovers and reuses the warmed gas by circulating it back through the heating element. Instead of continuously introducing fresh cold gas, the system recovers thermal energy from the outgoing gas and reuse it, significantly reducing energy consumption while maintaining a relatively simple device structure.

Inventive Principle:
Principle #34Discarding and recovering
