Wall-Mounted Electronic Device Fastener With Optical Fiber Winding Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for electronic devices, such as connection boxes for optical waveguides, often require optical fibers to run over the wall between the exit point and the device, leading to a non-compact structure.
Innovation Solution
A fastening device with a base plate featuring winding projections on the front side to accommodate optical fibers, allowing them to be wound between the base plate and the device, along with hold-down elements to prevent snagging, and recesses to reduce heat generation and facilitate compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device is mounted close to or above the exit point in the wall, then a compact design is achieved, but the optical fiber may become pinched between the base plate and the device
Solution Approach 1:
A winding projection is introduced as an intermediary element between the base plate and the device. This projection provides a dedicated path for the optical fiber to wind around, preventing it from being pinched while enabling compact mounting. The winding projection acts as a mediator that resolves the conflict between compact design and fiber protection.
2Reliability
If the optical fiber runs above the wall between the exit point and the device, then the fiber is protected from pinching, but a non-compact structure results
Solution Approach 1:
Instead of running the optical fiber horizontally above the wall, the winding projection guides the fiber to wind around itself in a three-dimensional configuration. This dimensional change allows the fiber to be protected from pinching while maintaining a compact overall structure, as the fiber path is folded back on itself within the mounting space.
3Stability of the object's composition
If the base plate has a large contact area with the device, then mounting stability is improved, but heat build-up on the rear of the device increases
Solution Approach 1:
Recesses are introduced into the base plate to create localized areas of reduced contact. These recesses allow heat to dissipate from the rear of the device while maintaining sufficient contact area for mounting stability. The local modification of the contact surface quality resolves the contradiction between stability and heat management.
