Securing Module Wire Management Snap-Fit Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exposed wires in small external electronic devices such as set-top boxes and portable projectors are prone to disconnection due to external forces, leading to device shutdown or signal interruption, as they lack protective measures.
Innovation Solution
A securing module comprising a positioning member, a fixing member, a wire management member, and a cover with hooks and clamping components that snap-fit to the case, securing the wires and preventing detachment by external forces, while allowing the connection end to be hidden within the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are exposed directly without protective measures, then the device structure is simple and easy to manufacture, but the wires are prone to disconnection when accidentally kicked or the device is hit
Solution Approach 1:
The securing module employs a nested structure where the hollow shell encloses the positioning member, fixing member, and wire management member. The wire management member is disposed on the fixing member, and the positioning member is disposed on the case, creating multiple nested levels that protect the wire connection while maintaining a compact form factor.
Solution Approach 2:
The securing module is divided into distinct functional components: a positioning member for locating the wire connection, a fixing member for securing the wire, a wire management member for organizing the cable, and a hollow shell for overall protection. This segmentation allows each component to perform its specific function effectively while enabling modular manufacturing and assembly.
2Reliability
If a protective cover is added to enclose the wire connection, then the wire is protected from external forces, but the device structure becomes more complex
Solution Approach 1:
The hollow shell serves as a protective enclosure that surrounds the positioning member, fixing member, and wire management member. This shell structure provides mechanical protection against external forces while maintaining a relatively simple geometric form that is easy to manufacture and integrate into the device housing.
Solution Approach 2:
The securing module integrates multiple protective functions into a single unified structure. The hollow shell combines structural support, wire protection, and organizational functions, while the clamping component integrates positioning and securing functions, reducing the overall number of separate components needed.
3Adaptability or versatility
If the wire management member is rotatably connected to allow rotation, then the wire can be routed flexibly, but the connection may become loose under external forces
Solution Approach 1:
The wire management member is rotatably connected to the fixing member, allowing it to rotate and adapt to different wire routing requirements. This dynamic connection enables flexible wire placement while the rotational degree of freedom accommodates variations in cable length and routing paths.
Solution Approach 2:
The clamping component is configured to clamp the positioning member and prevent rotation of the wire management member under external forces. This preliminary anti-action mechanism ensures that while the wire management member can rotate freely during installation and adjustment, it becomes firmly secured once the wire is in place, preventing accidental loosening during device operation.
4Ease of operation
If the clamping component is made movable between fixing and releasing positions, then the assembly and disassembly is easier, but the structure becomes more complex
Solution Approach 1:
The clamping component is designed to be movable between a fixing position where it clamps the positioning member securely, and a releasing position where it allows easy removal. This dynamic positioning capability is achieved through a simple mechanical linkage that translates linear motion into clamping force, enabling tool-free assembly and disassembly operations.
Solution Approach 2:
The clamping component incorporates a self-locking mechanism that automatically secures itself in the fixing position when the wire management member is inserted, eliminating the need for additional fastening operations. The component uses its own structural features to create the clamping action, reducing the need for external fasteners or complex adjustment mechanisms.

AI summary
A securing module includes a positioning member, a fixing member, a wire management member, and a cover. The positioning member is disposed on a case. The fixing member is passed through the positioning member and fixed to the case. The wire management member is disposed on the fixing member. The cover is assembled to the case. The cover includes at least one hook, a clamping component, and a hollow shell. The at least one hook and the clamping component are disposed on the hollow shell. The hollow shell covers the positioning member, the fixing member, and the wire management member. The clamping component is selectively moved between a fixing position and a releasing position. When the at least one hook is snap-fit to the case and the clamping component is located at the fixing position, the clamping component clamps the positioning member so that the hollow shell is fixed to the case.
