Deformable Lid Cable Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing cables to electronic devices, such as position measurement encoders, often require screws or other fasteners, which can increase device size, manufacturing complexity, and costs, while also failing to effectively prevent cable disconnection under force.
Innovation Solution
A method involving a casing with a deformable lid and channel that compresses the cable to secure it without external fasteners, using the lid's deformation to clamp the cable within a U-shaped channel, ensuring secure attachment and reduced part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or external fasteners are used to secure the cable to the casing, then the cable connection strength is improved, but the device size increases and manufacturing complexity increases
Solution Approach 1:
The cable securing function is merged with the existing lid structure. The lid is deformed to create an integrated cable clamp that combines the closing function and cable securing function into a single component, eliminating the need for separate fasteners and reducing part count while maintaining secure cable attachment
Solution Approach 2:
The lid structure serves dual purposes: it closes the opening and simultaneously secures the cable through deformation. The deformed lid creates a self-contained cable clamping mechanism that does not require external fasteners, allowing the same component to perform multiple functions
2Reliability
If screws or external fasteners are used to secure the cable, then the cable connection reliability is improved, but the device size increases
Solution Approach 1:
The cable securing function is integrated into the lid structure through deformation, combining what would traditionally be separate components (lid and cable clamp) into one. This eliminates the need for additional space-consuming fasteners while maintaining secure cable attachment
Solution Approach 2:
The lid is deformed to create a flexible clamping structure that conforms to the cable shape. This flexible deformation allows the lid to securely hold the cable without requiring rigid external fasteners, maintaining reliability while minimizing space
3Reliability
If traditional cable securing methods with multiple parts are used, then the cable connection is secured, but the number of parts increases and cost increases
Solution Approach 1:
Multiple functions (lid closing and cable securing) are merged into a single deformed lid structure, eliminating the need for separate cable clips, screws, or fasteners. This reduces the total part count while maintaining secure cable connection
Solution Approach 2:
The lid structure itself provides the cable securing function through deformation, making the system self-contained. The deformed lid creates its own cable clamping mechanism without requiring additional components, reducing part quantity and assembly complexity
4Reliability
If traditional assembly methods with screws and fasteners are used, then the cable can be securely attached, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The lid closing operation and cable securing operation are merged into a single action. As the lid is deformed to close the opening, it simultaneously clamps the cable in place, eliminating the need for separate fastening steps and reducing assembly time
Solution Approach 2:
The deformed lid structure automatically secures the cable during the closing process itself, without requiring additional assembly steps. The cable is secured as a byproduct of the lid deformation, making the assembly process more efficient
