Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed-length support arm is used in the knee brace, then the structural simplicity is maintained, but the adaptability to different user needs and the ease of operation for adjusting length are worsened
Solution Approach 1:
The support arm is divided into multiple telescopic segments (first support arm segment and second support arm segment) that can move relative to each other, allowing the overall length to be adjusted while maintaining structural integrity. This segmentation enables adaptability without requiring a complete redesign of the entire support arm structure.
Solution Approach 2:
The locking component is designed to be automatically locked or unlocked by the moving component through mechanical interaction, eliminating the need for separate locking mechanisms or complex control systems. The component itself performs the locking function, simplifying the overall device while maintaining adaptability.
2Ease of operation
If the support arm length is fixed, then the device complexity is reduced, but the ease of operation for adjusting to different user requirements deteriorates
Solution Approach 1:
The locking component automatically locks or unlocks in response to the moving component's movement, without requiring separate actuators, motors, or complex control systems. This self-locking mechanism makes the device easy to operate while keeping the adjusting mechanism simple.
Solution Approach 2:
The moving component acts as an intermediary that translates user input (pushing or pulling motion) into the locking or unlocking of the support arm segments. This intermediary mechanism simplifies the user's interaction while managing the complexity of the adjustment process internally.
3Ease of operation
If a telescopic adjusting mechanism with locking component is added, then the ease of operation for adjusting length is improved, but the device complexity increases
Solution Approach 1:
The locking component performs the locking function automatically through its mechanical interaction with the moving component, eliminating the need for separate locking mechanisms, buttons, or complex control systems. This self-service approach simplifies the overall device despite adding adjustment capability.
Solution Approach 2:
The locking and adjusting functions are merged into a single integrated mechanism where the moving component simultaneously controls both the position adjustment and the locking state. This consolidation reduces the number of separate components and simplifies the overall device structure.

AI summary
The present disclosure relates to the technical field of a rehabilitation protective gear, in particular to a telescopic adjusting structure of a support arm and a knee brace. The telescopic adjusting structure of the support arm comprises an adjusting arm and a support arm guard movably connected along the length direction, and further comprises a telescopic adjusting mechanism. The telescopic adjusting mechanism comprises a pushing component, which is movably provided on the support arm guard; a locking component, one end of which is connected with the pushing component, and the other end of which is clamped with the adjusting arm, wherein when the pushing component moves, the locking component is disengaged from or locked with the adjusting arm. The telescopic adjusting mechanism is provided, so that the extension length matching between the adjusting arm and the support arm guard is adjusted.
