Hanging Groove Design for Grounded Wire Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanging grounded structures are complex and costly, requiring additional materials and labor for fastening screws or pressing jigs, making it difficult to achieve a stable and automated hanging procedure for grounded wires.
Innovation Solution
A hanging grounded structure with a slanted hanging groove in a recessed portion of the housing, featuring a curved path with varying sections to guide and secure the grounded wire, ensuring stability and preventing it from falling off, and a top cover with a protrusion to clamp the wire in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening screw is used to fasten the grounded wire on the metal housing, then the grounded wire can be securely attached, but the material cost increases and additional production time is required
Solution Approach 1:
The patent extracts the fastening function from separate components (screws, pressing jigs) and integrates it into the housing structure itself through the hanging groove. The groove is formed directly on the housing surface, eliminating the need for additional fastening materials and simplifying the overall structure while maintaining secure attachment capability.
Solution Approach 2:
The housing structure serves its own fastening function through the hanging groove design. The groove's geometric features (slant arrangement, curved path, recessed portion) enable the grounded wire to be securely attached without requiring external fastening components. The structure fastens itself by providing an integrated mounting solution.
2Reliability
If a pressing jig is used to press the hanging grounded structure tightly, then the fastening requirement is met, but the material cost increases, the procedure becomes complicated, and automated hanging is difficult
Solution Approach 1:
The patent removes the pressing jig from the system by incorporating the pressing function directly into the housing's hanging groove structure. The groove's recessed portion and slant arrangement provide inherent mechanical constraint that secures the grounded wire without requiring external pressing tools or complex assembly procedures.
Solution Approach 2:
The housing structure with the hanging groove performs the fastening function autonomously. The geometric design of the groove (slant arrangement, curved path, recessed portion) automatically secures the grounded wire when assembled, eliminating the need for additional pressing operations or specialized jigs.
3Ease of operation
If the hanging groove is disposed in a slant arrangement with a curved path, then the hanging procedure is simplified and the grounded wire remains stable, but the groove must be precisely formed in the recessed portion
Solution Approach 1:
The patent employs a curved path design for the hanging groove instead of a straight line. The curved trajectory (including engaging sections and fixing section) guides the grounded wire smoothly through the groove, enhancing stability and simplifying the hanging motion. This curvature also distributes the wire along a more favorable geometric path for secure retention.
Solution Approach 2:
The hanging groove exhibits varying geometric properties at different locations: the slant arrangement at the entrance facilitates wire insertion, the curved path in the middle provides guidance and stability, and the recessed portion with fixing section ensures secure retention. Each segment of the groove has optimized local characteristics tailored to its specific function in the hanging process.

AI summary
A hanging grounded structure is disclosed and includes a housing, a recessed portion and a hanging groove. The housing includes an opening facing a first direction and a lateral wall extended along a second direction. The lateral wall has a top edge located at a periphery of the opening. The recessed portion is recessed inwardly on the lateral wall. The hanging groove is disposed on the lateral wall and located in the recessed portion. A grounded wire is hung on the housing through the hanging groove. The hanging groove includes a starting point located at the top edge and an ending point. A curved path is formed from the starting point to the ending point. The grounded wire is hung from an interior of the housing. An end of the grounded wire is disposed in the recessed portion through the hanging groove.
