Universal Substrate Case for Multi-Size Electrical Junction Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in accommodating substrates of different sizes in electrical junction boxes for vehicles, which requires multiple case types, increasing production costs due to the need for various case sizes.
Innovation Solution
A tubular substrate case with a bottom, featuring an open portion for selective insertion of substrates of different sizes, guided by a guide portion and restricted by first and second restricting portions, including pressing protrusions to ensure accurate positioning and movement restriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of cases are used to accommodate substrates of different sizes, then substrate accommodation flexibility is improved, but production costs increase
Solution Approach 1:
The substrate case is designed with a universal structure that can accommodate multiple substrate types (standard substrate and extended substrate) through a single case design. The case includes adjustable guide portions and restricting portions that can be positioned to match different substrate sizes, eliminating the need for multiple case types and reducing production costs while maintaining substrate accommodation flexibility
2Ease of manufacture
If substrate sizes are changed to reduce unneeded surface area, then cost is reduced, but the number of case types required increases
Solution Approach 1:
The substrate case incorporates dynamic and adjustable elements, including guide portions and restricting portions that can be repositioned or adjusted to accommodate different substrate sizes. This dynamic design allows a single case type to adapt to various substrate dimensions, reducing the need for multiple case types while maintaining cost-effectiveness through optimized substrate surface area

AI summary
A substrate case can be used in common with different types of substrates, and thus reduces production costs. A substrate case is tubular and has a bottom that includes an open portion into which a first substrate and a second substrate that has a different size can be selectively inserted. Guide portions are configured to guide movement of the first substrate and the second substrate in an insertion direction when the first substrate and the second substrate are selectively inserted through the open portion. A first restricting portion is configured to restrict movement of the first substrate when the first substrate has been guided by the guide portion and inserted to a regular position; and a second restricting portion that is configured to restrict movement of the second substrate when the second substrate has been guided by the guide portion and inserted to the regular position.
