Solution Overview
Problem
Existing fiber optic wall boxes lack convenient cable routing solutions and fail to provide adequate waterproof protection for outdoor electronic devices, leading to installation challenges and safety issues.
Innovation Solution
A wall box design featuring a square box body with a hinged cover, cable reversing structure, and sealing ring, allowing for flexible cable management, direction conversion, and waterproof sealing, with a fixing structure for various installation scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable routing is performed at various angles without a reversing structure, then cable installation flexibility is improved, but pulling force between non-parallel signal lines and adapters increases causing signal instability
Solution Approach 1:
The cable reversing structure acts as an intermediary component between the cable inlet and adapter. It includes a cable reversing block with threading holes that allows cables to enter at various angles while being properly oriented before connecting to the adapter, thus maintaining signal stability while preserving installation flexibility
Solution Approach 2:
The internal space of the box body is segmented into functional zones: cable inlet area, cable reversing structure area, and adapter mounting area. This segmentation allows independent optimization of each zone - the cable reversing structure can be specifically designed to handle angular cable entries while the adapter remains in a fixed position for stable connection
2Device complexity
If existing connector protection boxes are used without waterproof measures, then device simplicity is maintained, but protection performance against environmental factors deteriorates
Solution Approach 1:
A rubber sealing ring is installed at the opening of the box body where the box cover connects. This flexible sealing film creates a waterproof and dustproof barrier while maintaining the overall simplicity of the box structure, preventing environmental factors from infiltrating the internal components
Solution Approach 2:
The sealing ring is pre-installed at the box opening before the box cover is attached. This preliminary action ensures that the sealing interface is properly prepared in advance, creating effective protection against water and dust without requiring complex sealing mechanisms during assembly
