Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a non-adjustable chair is used in spa devices, then the device structure is simple, but user comfort is decreased

Engineering Contradiction:
Improveuser comfortVSAvoidchair structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The chair is transformed from a static, non-adjustable structure to a dynamic, multi-position adjustable structure. Motors are integrated into the chair mechanism to enable automatic adjustment of seat position, backrest angle, and footrest elevation, allowing the chair to adapt to different user preferences and treatment requirements while maintaining structural integration with the spa device frame

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If an adjustable chair with multiple motion capabilities is added, then user comfort and flexibility are enhanced, but device complexity increases

Engineering Contradiction:
Improvechair positioning flexibilityVSAvoidmotion mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The chair is designed as a multi-functional unit that integrates multiple motion capabilities (rotation, sliding, tilting) into a single structure. A centralized control system with multiple motors coordinates these different motion functions, allowing one chair assembly to perform various positioning tasks and adapt to different treatment scenarios without requiring separate mechanisms for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple chair adjustment functions are merged into an integrated system where the seat, backrest, and footrest are connected through a unified motion mechanism. The control system combines multiple motors and sensors into a single control unit that coordinates all adjustments, reducing the overall system complexity compared to having separate independent mechanisms for each adjustment function

Inventive Principle:
Principle #5Merging (Combining)
