Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional close-fit securing method is used, then the structure is simple, but the securing effect is reduced after plugging cycles or due to external force
Solution Approach 1:
The fastening apparatus is divided into multiple functional segments: a fastening body with first binding unit, a second binding unit, and a flexible element connecting them. This segmentation allows each component to perform its specific function while working together to provide reliable securing against external forces and plugging cycles.
Solution Approach 2:
The flexible element introduces dynamic capability to the fastening system, allowing it to adapt and respond to external forces. The flexible element can deform elastically under pulling forces and return to its original position, maintaining continuous securing pressure on the cable and connector throughout the operational lifecycle.
2Reliability
If prior fastening devices with multiple separate elements are used, then the securing effect is improved, but the installation and detachment become complicated
Solution Approach 1:
Multiple binding functions are merged into a single integrated fastening apparatus. The first binding unit, second binding unit, and flexible element are combined into one cohesive device that can be installed and detached as a single unit, eliminating the complexity of coordinating multiple separate fastening elements.
Solution Approach 2:
The fastening apparatus utilizes the elastic property of the flexible element to achieve self-securing. When the cable is inserted through the through hole, the flexible element automatically deforms and exerts clamping force, securing the cable without requiring additional fastening actions or complex assembly procedures.
3Reliability
If conventional fastening devices are used, then the securing effect is improved, but they cannot adapt to different connector sizes
Solution Approach 1:
The fastening apparatus is designed with universal adaptability through its flexible element and through hole configuration. The flexible element can accommodate cables of different diameters, and the through hole can be positioned at various locations on the fastening body, allowing the same apparatus to securely fasten different types and sizes of connectors and plugs.
Solution Approach 2:
The fastening apparatus allows for parameter adjustments including the position of the through hole on the fastening body and the dimensions of the flexible element. These parameter changes enable the apparatus to adapt to different cable diameters, connector sizes, and mounting requirements, providing versatile applicability across various electronic devices.
4Device complexity
If through holes with axial direction parallel to normal direction are used, then the structure is simple, but external pulling force cannot be reduced
Solution Approach 1:
The fastening apparatus introduces a dimensional change by allowing the through hole to be positioned at various locations and orientations on the fastening body, not limited to the center or parallel to the normal direction. This spatial reconfiguration creates a geometric relationship between the cable, connector, and fastening body that effectively resists external pulling forces through optimized force distribution.

AI summary
The present invention provides a fastening apparatus for retaining a connector coupled to an electronic device. The fastening apparatus for connector comprises a first fixing portion (104), a connection portion (102) and a second fixing portion (106). The first fixing portion (104) is disposed at one side of a connector (30) and has a first binding unit (1042). The connection portion (102) is formed on the first fixing portion (104) to connect the first fixing portion (104) to a housing (40) of an electronic device. The second fixing portion (106) is pivotally rotatable relative to the first fixing portion (104), the second fixing portion (106) including a second binding unit (1062) which engages the first binding unit (1042) when the second fixing portion (106) rotates to a specific location, so that a cable of the connector is enclosed between the first fixing portion (104) and the second fixing portion (106).
