Integrated Mounting Box Attachment Mechanism for Electric Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting boxes require complex structures and multiple parts to attach elongated electric installation members, consuming significant space.
Innovation Solution
Integration of attachment means into the box case, featuring ring segment attachment members with beveled access and planar stopping surfaces to securely hold elongated electric installation members, reducing part count and allowing for compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known attachment means are used to attach elongated electric installation members, then secure attachment is achieved, but device complexity and space consumption increase
Solution Approach 1:
The attachment means is integrated into the box case as a unified structure. The attachment member comprises a ring segment with radial supporting members that are formed as part of the box case, eliminating the need for separate attachment components and reducing overall device complexity while maintaining secure attachment functionality.
Solution Approach 2:
The box case serves multiple functions: it provides structural housing, defines mounting space, and incorporates integrated attachment means for securing elongated electric installation members. This multi-functionality reduces the need for additional separate components.
2Reliability
If known attachment means are used to attach elongated electric installation members, then secure attachment is achieved, but the space required increases
Solution Approach 1:
The attachment means is merged with the box case structure, utilizing the existing box case volume rather than adding separate attachment components. The radial supporting members extend from the box case wall, using the box case's structural space efficiently.
Solution Approach 2:
The attachment member ring segment is positioned within the box case structure, with radial supporting members extending inward from the box case wall. This nested arrangement allows the attachment means to occupy minimal additional space within the existing box case volume.
3Device complexity
If integrated attachment means are used, then part count is reduced, but attachment functionality must be maintained
Solution Approach 1:
The attachment member is segmented into a ring segment with multiple radial supporting members. This segmentation allows the integrated structure to maintain flexibility and effective attachment functionality while being formed as part of the box case, reducing part count without sacrificing performance.

AI summary
A mounting box comprising a box case (2) having at least one installation aperture (21) and attachment means comprising at least one attachment member (4, 6) for each of the at least one installation aperture (21), each attachment member (4, 6) having an access surface (42, 62) and a stopping surface (44, 64). The attachment means is adapted to allow movement of an elongated electric installation member (8) through an installation aperture (21) towards the mounting space and to resist reverse movement of the elongated electric installation member (8). Each attachment member (4, 6) is an integral part of the box case (2) such that the box case (2) and each attachment member (4, 6) are made from a same material.
