Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed backrest is used, then the structure is simple and stable, but the function is single and cannot be adjusted according to actual needs
Solution Approach 1:
The backrest is transformed into a multi-functional device by integrating a pull-out board, placing cavities, and supporting abutments. The backrest serves not only as a support structure but also as a mounting surface for the auxiliary function board, which provides working, resting, and entertainment capabilities, thus achieving multi-functionality.
Solution Approach 2:
The auxiliary function board is divided into modular components including a bottom plate, supporting plate, pull-out plate, and fixing device. These segmented parts can be independently assembled and adjusted, allowing the system to adapt to different functional needs while maintaining manageable structural complexity.
2Ease of operation
If a fixed backrest board is used, then the structure is stable, but it cannot be folded and carried easily
Solution Approach 1:
The backrest system transitions from a static fixed structure to a dynamic adjustable system. The pull-out plate can extend and retract, the supporting plate can be pulled out, and the entire auxiliary function board can be folded back against the backrest. The fixing device with clamping arms provides dynamic locking to ensure stability during use while allowing easy deployment and storage.
3Adaptability or versatility
If a simple backrest is used, then the structure is easy to manufacture, but it lacks adjusting mechanisms for different positions and angles
Solution Approach 1:
The system incorporates adjustable mechanisms including a pull-out plate with fixed positions, a supporting plate that can be pulled out to different extents, and a fixing device with movable clamping arms. These dynamic elements allow the backrest to adapt to different positions and angles while using relatively simple mechanical structures that are manufacturable with standard processes.
4Adaptability or versatility
If a foldable auxiliary function board is added to the backrest, then the functionality and adjustability are improved, but the device complexity increases
Solution Approach 1:
The auxiliary function board is merged with the backrest structure through the fixing device that integrates with the backrest's metal rods. The bottom plate, supporting plate, and pull-out plate are combined into a single integrated assembly that folds compactly against the backrest. This merging reduces the need for separate components and simplifies the overall device complexity while maintaining functional flexibility.
