Solution Overview

Problem

Existing spinal thermotherapy devices struggle to provide appropriate massage for users with asymmetrical bodies, as they cannot accurately measure and adjust the load on each side of the spine, leading to inconsistent massage intensity.

Innovation Solution

A massage device with a separation-type pressing part, featuring independent lifting/lowering mechanisms for each side of the spine, combined with load detection and control units to adjust the pressing force based on asymmetrical body conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single supporting member is used to simultaneously raise or lower pressing members on both sides, then the device structure is simple and easy to manufacture, but it cannot provide appropriate massage to users with asymmetrical bodies

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidadaptability to asymmetrical bodies
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The single supporting member is divided into first and second supporting members that independently support pressing members on opposite sides. This segmentation allows each side to be adjusted separately, enabling the device to adapt to asymmetrical body conditions while maintaining structural simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single load measuring member is used to measure total load, then the measurement system is simple, but it cannot accurately calculate load on each pressing member for asymmetrical users

Engineering Contradiction:
Improvemeasurement system complexityVSAvoidload measurement accuracy per pressing member
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The single load measuring member is replaced with separate first and second load measuring members, each positioned to measure load on one side independently. This segmentation enables accurate measurement of asymmetric load distribution while keeping the measurement system relatively simple through distributed sensing.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If pressing members are adjusted simultaneously on both sides, then the control system is simple, but it cannot accommodate users with scoliosis or asymmetrical posture

Engineering Contradiction:
Improvecontrol system simplicityVSAvoidaccommodation of asymmetrical posture
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The simultaneous adjustment mechanism is segmented into independent first and second lifting/lowering mechanisms, each controlled separately. This allows the control system to adjust pressing members on opposite sides independently, accommodating asymmetrical postures while maintaining relatively simple control architecture through modular actuation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system is designed to accept and respond to asymmetric conditions by allowing different pressing forces and positions on each side. The independent supporting members and lifting/lowering mechanisms enable asymmetric adjustment patterns that match asymmetric body conditions, directly applying the asymmetry principle to improve adaptability.

Inventive Principle:
Principle #4Asymmetry
