Electronic Housing Cable Retention via Internal Depression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housings for electronic devices with cable hooks face issues of increased outside dimensions and structural strength requirements, leading to larger member sizes and potential cable dislodgment.
Innovation Solution
A housing design incorporating a cable housing with a depression and protrusion structure that uses a combination of spaces between the protrusion and sidewalls to securely house a cable, utilizing the restoring force of the cable to prevent dislodgment without increasing the housing's outside dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hook structure is added to the housing to store a cable, then the cable can be stored, but the outside dimensions of the housing become large
Solution Approach 1:
The cable storage structure is nested within the housing by forming a depression in the rear surface that receives and houses the cable. The cable groove and protrusion structure are integrated into the housing body, allowing the cable to be stored inside the housing rather than requiring external hooks, thus maintaining compact outside dimensions while providing cable storage capability
Solution Approach 2:
The cable storage solution transitions from a two-dimensional external hook to a three-dimensional internal depression structure. By utilizing the internal space of the housing and creating a recessed area, the design accommodates the cable within the existing footprint, avoiding external dimension expansion
2Reliability
If the hook is made strong against bending to prevent breakage, then reliability improves, but the members constituting the hook have to be made large
Solution Approach 1:
The cable retention mechanism is segmented into multiple functional elements: a depression for housing the cable, a groove for positioning, and a protrusion for retention. This segmentation allows each element to be optimized for its specific function with appropriate size and strength, avoiding the need for a single oversized hook structure
Solution Approach 2:
The protrusion is designed with localized geometric features that provide high strength against bending at critical points while maintaining overall compact dimensions. The specific shape and positioning of the protrusion create effective mechanical retention without requiring excessive material or size
3Device complexity
If a simple hook structure is used, then device complexity is low, but the cable may fall off
Solution Approach 1:
Multiple cable retention functions are merged into a single integrated structure on the rear surface of the housing. The depression, groove, and protrusion work together as a unified mechanism to receive, position, and retain the cable, providing reliable cable storage without requiring multiple separate components or complex assembly

AI summary
A housing of the present invention can house an electronic device therein and is provided with a cable housing capable of housing a part of a cable. The cable housing is formed of a depression and a protrusion extending out from a part of a first sidewall of the depression toward a fourth sidewall of the depression along a second sidewall, a third sidewall, and a bottom wall of the depression. At a boundary portion between a housing area and a passing area, a distance between the second sidewall and the third sidewall in the housing area is longer than a distance between the second sidewall and the third sidewall in the passing area.
