Solution Overview
Problem
Existing fiber optic connection boxes are difficult to install, bulky, and lack secure closure mechanisms, posing risks of accidental removal or unintentional unlocking.
Innovation Solution
A connection box design featuring a base element for wall fastening, a protective member with a locking mechanism that includes a labeling field, and a locking element that can be linearly or rotatably moved to ensure secure closure and easy identification of connections, along with cable and fiber management features to prevent bending and tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is implemented to prevent accidental removal, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into modular components: a locking element with detent features, a locking opening with corresponding detent geometry, and a spring element. This segmentation allows each component to perform its specific function while maintaining overall simplicity and reliability of the closure system.
Solution Approach 2:
The locking mechanism is designed to be self-latching through the interaction of detent features and spring force. Once engaged, the locking element automatically maintains the closed position without requiring continuous external force or complex control systems, achieving reliable secure closure through self-sustaining mechanical action.
2Volume of moving object
If the junction box is made compact to reduce wall protrusion, then volume is reduced, but ease of operation deteriorates
Solution Approach 1:
The junction box utilizes wall mounting to shift the volume constraint from three-dimensional space to a two-dimensional wall surface. By mounting flat against the wall and protruding minimally, the design optimizes space utilization while maintaining adequate internal volume for fiber management operations through efficient vertical and horizontal arrangement of components.
Solution Approach 2:
The locking element is designed with movable capability between locked and unlocked positions, allowing the compact structure to dynamically open for installation/maintenance and close for protection. This dynamic feature enables the small form factor to accommodate full installation operations without compromising ease of operation.
3Ease of operation
If the cover is made easily removable for access, then ease of operation is improved, but reliability deteriorates due to unintentional unlocking
Solution Approach 1:
The locking function is extracted as a separate mechanical feature (locking element with detent) distinct from the cover itself. This allows the cover to be easily identified and operated while the dedicated locking mechanism provides reliable secure closure, separating the ease of operation function from the reliability function.
Solution Approach 2:
The locking element acts as an intermediary between the cover and base element, mediating the connection with a controlled release mechanism. This intermediary component enables intentional easy removal while preventing unintentional unlocking through its detent-based engagement design.
4Ease of operation
If a separate labeling field is added for identification, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The labeling field is merged with the locking element, combining identification functionality with the existing mechanical component. This integration allows the locking element to serve dual purposes: providing secure closure through its mechanical function and offering identification through the integrated labeling field, thereby improving ease of operation without increasing device complexity.
Solution Approach 2:
The locking element is designed with multi-functionality, serving both as a mechanical locking component and as a labeling carrier. This universal design allows a single component to fulfill multiple functions (securing the cover and providing identification), eliminating the need for separate labeling fields and maintaining simplicity.
