Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional balance-training equipment is used, then the structure is simple, but the equipment cannot provide continuous reciprocating motion controlled by user's posture and energy
Solution Approach 1:
The patent applies dynamics by making the balance-training equipment movable and adjustable through a linkage system with multiple links (first link, second link, third link) that can reciprocate between extended and retracted positions. This allows the equipment to adapt to different user postures and energy levels, transforming from a static structure to a dynamic one that responds to user input while maintaining controlled motion through the mechanical linkage system.
2Reliability
If conventional balance-training equipment is used, then the device complexity is low, but the training effectiveness is insufficient
Solution Approach 1:
The patent implements feedback through the linkage system where the position and motion of the links respond to and reflect the user's posture and energy input. The mechanical feedback loop allows the transmission unit to adjust the reciprocating motion based on user actions, ensuring that the training effectiveness is optimized while maintaining a manageable structural complexity through pure mechanical means.
3Ease of operation
If a linkage system with multiple links is implemented, then the platform can reversibly slide-swing for optimal balance training, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the transmission system into distinct modular components: a first link, a second link, and a third link, each performing a specific function in the reciprocating motion sequence. This segmentation allows the complex motion control to be broken down into manageable segments that can be independently analyzed and maintained, improving ease of operation while managing overall device complexity through functional modularity.

AI summary
A reversibly slide-swingable balance-training apparatus includes a base unit, a transmission unit mounted in the base unit and providing a movement-constraining eccentric shaft and a power-maintaining rotary member for rotating the movement-constraining eccentric shaft continuously, one or a pair of linkages each having a first link pivotally connected to the movement-constraining eccentric shaft of the transmission unit, a second link pivotally coupled between the first link and the base unit and a third link pivotally connected to the second link, and a platform pivotally connected to the first link and third link of each linkage. Subject to the oscillation motion of the links of the linkage counteracting the postures of the user and the functioning of the movement-constraining eccentric shaft and the continuation of the energy of the power-maintaining rotary member, the platform is reversibly slide-swinging for best balance training.
