Removable Cable Storage Element for Junction Box Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing junction boxes require installers to support both the junction box and a mobile basket simultaneously when handling excess cable, making the operation impractical and posing a risk to the equipment.
Innovation Solution
A junction box design featuring a removable storage element with a cable entry passage and storage space for excess cable, allowing the storage element to be detached from the housing body, facilitating easier handling and maintaining connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile basket is used to store excess cable inside the junction box, then the excess cable can be stored and accessed, but the installer must support both the junction box and the basket simultaneously, making the operation impractical and posing a risk to the equipment
Solution Approach 1:
The storage element is segmented from the junction box housing, allowing it to be removed and handled independently. This segmentation enables the storage element to be detached, reducing the complexity of handling equipment by eliminating the need to support both the junction box and basket simultaneously.
Solution Approach 2:
The storage element is extracted from the junction box as a removable component. This extraction allows the storage element to be taken out when not needed, simplifying the overall system and reducing handling complexity during installation and maintenance operations.
2Reliability
If the storage element is fixed inside the junction box, then the excess cable is securely stored, but it interferes with the closing of the box and hinders installer access during installation and maintenance operations
Solution Approach 1:
The storage element is designed with dynamic characteristics, being removable rather than fixed. This allows the storage element to be positioned inside the junction box when cable storage is needed, and removed when installer access is required, providing flexibility that resolves the contradiction between security and accessibility.
Solution Approach 2:
The storage element is pre-configured with cable management features such as guide channels and retention structures that secure cables before the element is installed in the junction box. This preliminary preparation ensures secure cable storage while allowing easy removal when access is needed.
3Ease of operation
If the storage element is designed to be removable, then installer access to excess cable is improved, but the cable management complexity increases
Solution Approach 1:
The storage element merges multiple functions into a single component: cable storage, cable guidance, and cable retention. By combining these functions in one removable element, the overall cable management complexity is reduced compared to having separate mechanisms for each function.
Solution Approach 2:
The storage element is designed as a multi-functional component that serves as both a storage container and a cable management system. It includes integrated features such as entry passages for cable access, internal structures for cable coiling, and retention mechanisms, all in one removable unit that simplifies overall system complexity.
