Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing emergency wheel solutions are used, then the attachment can be provided for vehicle wheels with flat tires, but the attachment process is complex and requires extensive tools or expertise
Solution Approach 1:
The emergency wheel attachment is divided into two semicircular segments that can be separately handled and attached. This segmentation allows the attachment to be installed in a simpler manner compared to a complete circular attachment, reducing the complexity of the attachment process while maintaining structural integrity when assembled.
Solution Approach 2:
The attachment incorporates movable elements including a movable support element that can shift between positions, and releasable fastening elements that can be easily engaged and disengaged. This dynamic design allows for simple attachment and removal operations without requiring complex tools or extensive expertise.
2Reliability
If existing emergency wheel solutions are used, then the attachment can be provided for vehicle wheels with flat tires, but secure fastening is difficult and time-consuming
Solution Approach 1:
The fastening elements are pre-configured in the attachment segments, with fastening means positioned to engage with corresponding features on the wheel rim. This preliminary arrangement allows for quick and secure fastening without requiring complex assembly operations or extensive time during the emergency attachment process.
Solution Approach 2:
The attachment design includes self-aligning and self-fastening features where the movable support element and releasable fastening elements automatically engage with the wheel rim structure. This self-service mechanism reduces the time required for secure fastening and eliminates the need for complex manual operations or specialized tools.
3Stability of the object's composition
If a complete circular attachment is used, then the structure is stable, but the attachment is difficult to store and transport
Solution Approach 1:
The attachment is divided into two semicircular segments that can be detached from each other. This segmentation allows the attachment to be stored in a compact manner when not in use, reducing the volume required for storage and transport while maintaining structural stability when the segments are assembled and fastened to the wheel rim.
Solution Approach 2:
The attachment incorporates movable elements including a movable support element that can shift between positions, enabling the attachment to transition between a compact stored state and a stable deployed state. This dynamic capability allows the attachment to maintain structural stability when installed while occupying minimal storage space when not in use.
4Adaptability or versatility
If a rigid fixed structure is used, then the attachment is simple to manufacture, but the attachment cannot adapt to different wheel sizes or positions
Solution Approach 1:
The attachment includes a movable support element that can shift between different positions, allowing the attachment to adapt to different wheel sizes and positions. This dynamic adjustment capability is achieved through relatively simple mechanical means rather than complex adjustable mechanisms, maintaining ease of manufacture while providing versatility.
Solution Approach 2:
The attachment design allows for changes in geometric parameters such as the position of the support element and the orientation of the segments to accommodate different wheel configurations. These parameter changes enable adaptability to different wheel sizes and positions without requiring complex adjustable mechanisms, maintaining simplicity in manufacturing.
