Electric Junction Box Wire Routing Fixing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric junction boxes, the routing of electric wires between electronic components and the lid portion often causes the wires to swell, pressing the lid and leading to its deformation, which existing solutions fail to prevent effectively.
Innovation Solution
The electric junction box incorporates fixing members with rod-shaped arm portions that intersect with the attachment direction of the lid, allowing the electric wires to be fixed on a face that prevents swelling both of the wire and the lid, utilizing notches on the partition wall to regulate wire position and prevent sticking between the housing and lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electric wires are routed between the electronic component and the lid portion, then the wire routing function is achieved, but the lid portion swells and deforms due to wire pressure
Solution Approach 1:
A fixing member is introduced as an intermediary component between the electric wire and the lid portion. This fixing member has a face that intersects with the attachment direction of the lid portion, providing a support surface that prevents the wire from directly pressing against and deforming the lid portion while still allowing the wire to be routed between the electronic component and the lid.
2Volume of moving object
If the accommodating space is small, then the compact design is achieved, but the electric wire presses the lid portion causing swelling
Solution Approach 1:
The fixing member utilizes a dimensional approach by providing a face that intersects with the attachment direction of the lid portion. This creates a new spatial dimension for wire support, allowing the wire to be positioned and fixed in a way that prevents it from pressing against the lid portion even in compact accommodating spaces.
3Device complexity
If fixing members are integrated with the partition wall, then the device complexity is reduced, but the wire fixing function must be maintained
Solution Approach 1:
The fixing member is merged with the partition wall, combining two structural elements into one integrated component. This integration reduces the overall device complexity by eliminating separate fixing member components while the partition wall itself is designed with the necessary features (face intersecting with lid attachment direction) to maintain the wire fixing function effectively.

AI summary
An electric junction box includes a housing configured to accommodate an electronic component, and a lid portion attached to the housing so as to cover an opening of the housing. An electric wire connected to the electronic component is routed between the electronic component and the lid portion. The housing includes a fixing member fixing the electric wire. The fixing member has a face intersecting with an attachment direction of the lid portion and fixes the electric wire to the face.
