Solution Overview
Problem
Existing optical fiber splicing boxes are limited in connecting multiple fibers, cannot handle cut fibers without connectors, have poor waterproofing, and are costly and labor-intensive to assemble, failing to meet diverse engineering requirements.
Innovation Solution
An optical fiber splicing box design featuring a buckled box body and cover with waterproof rings, cable inlets/outlets, and positioning structures for single and multiple fibers, including a cable storage system and waterproof mechanisms to accommodate cut fibers with connectors, ensuring effective waterproofing and protection against environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the splicing box is designed to accommodate only straight-through cables, then the structure is simple, but it cannot handle cut fibers requiring connectors
Solution Approach 1:
The splicing box is designed with dual cable inlet/outlet configurations: one set for straight-through cables and another set for cut cables with connectors. This universal design enables the same box to handle multiple cable types without requiring separate specialized boxes, directly resolving the contradiction between adaptability and structural simplicity.
2Quantity of substance
If multiple optical fibers are connected by increasing cable inlet/outlet, then the number of connected fibers increases, but the wiring structure becomes more complex and assembly cost increases
Solution Approach 1:
The patent implements a nested wiring structure where multiple fiber optic cables are organized in a hierarchical arrangement within the splicing box. The cable inlet/outlet structures are nested with positioning structures that guide and organize multiple fibers systematically, allowing high fiber capacity while maintaining manageable structural complexity through orderly nesting rather than chaotic arrangement.
3Ease of manufacture
If the splicing box structure is simplified, then the assembly cost decreases, but the waterproof effect deteriorates
Solution Approach 1:
The waterproof ring is integrated directly into the box body structure rather than being a separate component requiring additional assembly steps. This merging of the waterproof function into the existing structural elements achieves effective waterproofing while minimizing assembly complexity and cost, resolving the contradiction between manufacturing simplicity and waterproof reliability.
4Reliability
If the box body and box cover are tightly buckled, then the waterproof effect improves, but the assembly and disassembly become more difficult
Solution Approach 1:
The buckling structure incorporates dynamic elements that allow the connection to be easily engaged and disengaged through simple rotational or linear motions, while maintaining a tight sealed connection during operation. The design enables the box cover to transition between an accessible state for assembly/disassembly and a tightly sealed state for operation, resolving the contradiction between waterproof reliability and operational ease.

AI summary
An outdoor optical fiber splicing box, a cable storage structure is fixed at the bottom of the inner cavity, a plurality of wiring structures are stacked on the upper side of the cable storage structure, and two sides of the wiring structure are provided with a multi-fiber supporting mechanism and a single-fiber supporting mechanism, which are fixed at the bottom of the inner cavity. The single-fiber and multi-fiber supporting mechanisms are all arranged on the side of the wiring structure. The box body is provided with a first and a second cable inlet/outlets, and the first cable inlet/outlet is provided with a single optical fiber waterproof structure. The second cable inlet/outlet is provided with a multi-fiber waterproof structure, and the waterproof effect is good. At the same time, the single-fiber and multi-fiber supporting mechanisms can protect the optical fiber cable from vibration, impact, cable stretching, and twisting.
