Solution Overview
Problem
Existing fiber optic distribution devices lack flexible and cost-effective installation options for fiber optic management units both inside and outside buildings, limiting their adaptability and efficiency.
Innovation Solution
A fiber optic distribution device with a back wall featuring intersecting sets of parallel grooves allows for flexible mounting of fiber optic management units using screws or snap hooks, enabling simple, reliable, and cost-effective installation and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed mounting positions with holes are used in the back wall, then the structure is simple and manufacturing is easy, but the installation positions for fiber optic management units lack flexibility
Solution Approach 1:
The back wall structure is segmented into multiple parallel grooves instead of using a single fixed mounting pattern. These grooves divide the mounting space into discrete positions along the grooves, allowing fiber optic management units to be installed at various locations while maintaining structural simplicity.
Solution Approach 2:
The mounting system transitions from fixed two-dimensional hole positions to a one-dimensional groove-based system that allows continuous positioning along the groove length. This dimensional change enables flexible installation positions while keeping the back wall structure relatively simple.
2Adaptability or versatility
If multiple mounting holes are provided in the back wall, then installation positions increase, but manufacturing complexity and cost increase
Solution Approach 1:
Instead of providing multiple discrete mounting holes throughout the back wall, the structure is segmented into a few parallel grooves. These grooves serve as continuous mounting tracks that replace numerous individual holes, reducing manufacturing complexity while increasing the number of available mounting positions.
Solution Approach 2:
The parallel grooves serve multiple functions: they provide mounting positions for fiber optic management units, guide the placement of fastening elements, and allow flexible positioning along their length. This multi-functionality eliminates the need for numerous specialized mounting holes.
3Ease of operation
If fixed hole positions are used for mounting, then manufacturing is cost-effective, but installation flexibility and adaptability are limited
Solution Approach 1:
The mounting system transitions from static fixed hole positions to dynamic groove-based positioning that allows fiber optic management units to be installed at various locations along the grooves. This dynamic capability provides installation flexibility while maintaining a relatively simple groove structure.
Solution Approach 2:
The mounting parameters change from fixed coordinates (hole positions) to variable positions along continuous grooves. This parameter change enables flexible installation while the groove geometry itself remains simple and cost-effective to manufacture.
