Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple folding portions are added to enable various shapes, then adaptability and versatility are improved, but interference between folding portions increases and reliability deteriorates
Solution Approach 1:
The guide unit is divided into multiple independent connection parts (first connection part, second connection part, third connection part) that can independently control different folding portions. Each connection part is associated with a specific folding portion, allowing segmented control of the folding sequence to prevent interference between multiple folding operations.
Solution Approach 2:
The guide unit determines and establishes the folding sequence in advance through its mechanical structure. The connection parts are positioned and configured to guide the folding portions to fold in a predetermined order, preventing interference before it occurs by establishing the correct sequence beforehand.
2Ease of operation
If folding portions are made compact to improve portability, then ease of operation is improved, but alignment precision deteriorates causing interference
Solution Approach 1:
The connection parts act as intermediary elements between the folding portions and the guide unit. These intermediaries transmit and regulate the folding motion, ensuring that even in compact configurations, the alignment between folding portions is maintained through the mediating action of the connection parts.
Solution Approach 2:
The guide unit utilizes elastic parts that can change their physical state (compressed or extended) to accommodate different folding configurations. By changing the physical parameters of the elastic components, the system maintains proper alignment across various compact and expanded states without interference.
