Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the top cover is removed to access stored fishing equipment, then accessibility is improved, but durability and portability are compromised
Solution Approach 1:
The top cover is divided into multiple hatches that can be opened independently. This allows users to access specific compartments without removing the entire cover, improving accessibility while maintaining the integrity and protection of the overall structure, thus preserving durability and portability.
Solution Approach 2:
The hatches are designed to be pivotally connected and movable, allowing dynamic access to different compartments. The zipper mechanism enables the cover to be opened and closed smoothly, providing easy accessibility while the cover remains attached to maintain structural integrity and durability.
2Ease of operation
If a zipper is attached to fabric, then ease of operation is improved, but durability deteriorates due to stress concentration
Solution Approach 1:
The zipper is attached directly to the hard plastic base instead of fabric. This changes the attachment substrate from a flexible material that concentrates stress to a rigid material that distributes stress, thereby maintaining ease of operation while significantly improving durability at the attachment points.
