Split Pressing Mechanism for Asymmetrical Spinal Massage Control
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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
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.
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.
