Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fastening device is used with a limited diameter ratio between the anchoring protrusion and the element, then the device structure is simple, but the adaptability and versatility are reduced
Solution Approach 1:
The fastening device is divided into separate functional components: an anchoring protrusion with a neck portion, a locking component with a bore, and an element with an opening. This segmentation allows each component to be independently designed and optimized for its specific function, enabling the device to accommodate various diameter ratios while maintaining structural integrity and ease of assembly.
Solution Approach 2:
The locking component serves multiple functions: it provides axial fixation through the bore, acts as a lock on the connecting link, and enables reversible attachment. The overlapping geometry of the bore and opening creates a universal connection mechanism that works with different diameter ratios, making the device adaptable to various applications without requiring design changes.
2Ease of operation
If a traditional fastening device with fixed geometry is used, then the manufacturing process is simple, but the ease of operation and adjustability are limited
Solution Approach 1:
The fastening device incorporates dynamic elements that allow reversible attachment and detachment. The overlapping geometry of the locking component's bore and the element's opening enables the connection to be made and broken easily through axial movement, providing operational flexibility while maintaining a relatively simple manufacturing process for each individual component.
3Adaptability or versatility
If the diameter ratio between anchoring protrusion and element is restricted to 1:4, then the connection is secure, but the adaptability to different applications is reduced
Solution Approach 1:
The device allows for parameter changes in the diameter ratio between the anchoring protrusion and the element. By designing the locking component with a bore that partially overlaps the element's opening, the system can accommodate a wider range of diameter ratios while maintaining reliable connections. The overlapping geometry ensures that the connection remains secure across different size proportions, expanding application range without compromising reliability.

AI summary
An assembly for axial fixation of at least one element having an opening formed therein to an article. The assembly includes an anchoring protrusion attached to the article, which includes a distal end and a neck portion, and at least one locking component having a bore disposed therein, the locking component having at least a portion which is at least one of flexible and elastic. The anchoring protrusion extends through the opening in the element and through the bore of the locking component. An overlap region between the opening of the element and the bore of the locking component, is substantially equal to the diameter of the neck portion, such that the element and the at least a portion of the locking component form a locking unit.
