Cable Clip Snap-Fit Engagement for Protective Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables used to transmit data and power to portable devices encased in protective casings often detach due to external impacts or entanglements, leading to interruptions in data and power transmission.
Innovation Solution
A cable clip with a clip housing and retaining arms that establish a snap-fit engagement with the protective casing, securing the cable in place and creating a water-tight seal, using resilient and flexible tangs for secure attachment and a removable cap for sealing the cable connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is directly connected to a portable device in a protective casing, then the connection is simple and easy to attach, but the cable becomes detached when jostled or jarred by external impact
Solution Approach 1:
The cable attachment system is divided into separate functional components: a cable clip assembly with resilient tangs for securing the cable, a protective casing with engagement features, and a connector. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The cable clip is pre-installed within the protective casing before the cable is connected to the portable device. The resilient tangs are pre-positioned to engage with corresponding features on the casing, creating a secure anchor point that prevents cable detachment during subsequent use or impact events.
2Reliability
If a secure cable attachment mechanism is implemented, then cable detachment is prevented, but the device complexity increases
Solution Approach 1:
The cable clip assembly utilizes the existing structural features of the protective casing (engagement openings, retaining arms) to secure itself and the cable. The resilient tangs automatically engage with the casing features when the cable is inserted, eliminating the need for separate fastening mechanisms or complex assembly procedures.
Solution Approach 2:
The cable clip assembly is integrated into the protective casing structure, combining the cable securing function with the existing casing design. The resilient tangs and engagement features are incorporated as part of the casing assembly rather than as separate add-on components, maintaining a unified and relatively simple device structure.
3Object-affected harmful factors
If the cable connection is made secure and sealed, then water-tight sealing is achieved, but the ease of operation for cable removal decreases
Solution Approach 1:
The cable attachment system incorporates resilient (flexible) tangs that can dynamically adjust their position. During normal use, the tangs maintain a secure, water-tight seal with the protective casing. When cable removal is needed, the tangs can flex or deform to allow the cable connector to be pulled out, providing ease of operation while maintaining sealing during operation.
