Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If joint connectors are housed inside the electrical junction box, then water and foreign matters are prevented from entering, but interference with wire bundles and electronic components occurs
Solution Approach 1:
The electrical junction box is segmented into multiple housing spaces using partition walls. Each partition wall includes a locking part that creates a dedicated locked state for joint connectors, isolating them from electronic components and wire bundles while maintaining protection from water and foreign matters.
Solution Approach 2:
The locking part is positioned in a direction orthogonal to the insertion direction of the electronic component block. This orthogonal arrangement allows the joint connector to be locked without interfering with the electronic components housed in the same electrical junction box, resolving the spatial conflict.
2Stability of the object's composition
If fixing position is set for joint connectors, then secure fixation is achieved, but additional components and design considerations are required
Solution Approach 1:
The locking part is integrated into the partition wall structure of the electrical junction box, merging the fixation function with the existing housing structure. This eliminates the need for separate fixing components and simplifies the overall design while achieving secure fixation of the joint connector.
Solution Approach 2:
The locking part automatically locks the joint connector in place through its structural design, without requiring additional fixing operations or components. The joint connector is secured by simply being housed in the electrical junction box, reducing assembly complexity.
3Reliability
If locking part is positioned to lock joint connector, then secure locking is achieved, but interference with electronic component block occurs
Solution Approach 1:
The locking part is positioned in a direction orthogonal to the insertion direction of the electronic component block. When the electronic component block is inserted, the locking part is already in a locked state that prevents interference with the electronic component block, while still effectively locking the joint connector.

AI summary
In a wire harness, a frame includes a partition wall. The partition wall includes a locking part that locks a joint connector housed in a sectioned space part from an opening part on the lower side. When an electronic component block is being fixed to a frame by a fixing part, the locking part is positioned on the lower side than the electronic component block is and isolated from the electronic component block in the orthogonal direction that is orthogonal to the insertion direction (first height direction) of the electronic component block when the frame is viewed from the opening part on the lower side.
