Roller Locking Mechanism for Solar Wire Slack Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wire management systems for solar panels are inefficient, costly, and prone to failure due to exposure to environmental factors, leading to increased electrical resistance and reduced system efficiency, while existing methods constrain wire runs to suboptimal paths and fail to maintain wire integrity over the lifespan of the solar panel system.
Innovation Solution
A locking apparatus with a housing, fixing member, and locking mechanism that allows movement in one direction and resists movement in the opposite direction, featuring a lock path and slack management opening to secure wires efficiently, using materials like stainless-steel cables and rollers to manage wire slack and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional wire management methods are used to secure wires to solar panel frames or mounting structures, then wires are supported at fixed points, but wire runs are constrained to suboptimal paths increasing length and electrical resistance
Solution Approach 1:
The patent applies the dynamics principle by using a roller mechanism that allows the wire to move dynamically along the locking apparatus rather than being fixed at discrete points. The roller can rotate to accommodate wire tension and positioning changes, enabling the wire to follow an optimized path while maintaining secure support. This dynamic approach reduces wire run length compared to traditional fixed-point management systems.
2Reliability
If wires are secured to mounting structures at fixed points, then wire support is provided, but the wire management system fails after exposure to environmental factors like sunlight, wind, water, heat, and cold
Solution Approach 1:
The locking apparatus is constructed using composite materials including stainless steel components for structural strength and corrosion resistance, combined with UV-stabilized polymer elements for weather resistance. This composite construction enables the system to withstand environmental factors such as sunlight, rain, snow, heat, and cold throughout the entire service life of the solar panel system, preventing the degradation and failure experienced with traditional single-material systems.
Solution Approach 2:
The patent employs parameter changes by selecting materials with specific properties optimized for outdoor environmental conditions. The stainless steel components provide resistance to corrosion and structural degradation, while the polymer components are formulated with UV stabilizers and weather-resistant additives. These material parameter selections ensure the wire management system maintains its functional properties throughout the extended service life required for solar panel applications.
3Reliability
If traditional wire management systems are used, then wires are supported along the run, but the systems loosen over time and/or cut the protective cover of solar panel wiring
Solution Approach 1:
The roller mechanism serves as an intermediary between the wire and the locking apparatus housing. Instead of the wire directly contacting and potentially damaging the housing or loosening over time, the roller acts as a mediating element that distributes contact forces, prevents cutting of the wire protective cover, and maintains consistent friction for reliable wire retention without degradation over time.
4Loss of energy
If wires are routed along shortest paths from panel to inverter, then electrical efficiency is improved, but traditional mounting structures cannot support wires at optimal locations
Solution Approach 1:
The locking apparatus is designed with universal adaptability to be mounted on various solar panel frame configurations and mounting structure types. The apparatus can be installed at multiple locations along the wire run, not just at fixed predetermined points, allowing the wire to be routed along the shortest possible path while maintaining secure support. This multi-functional mounting capability enables optimization of wire length and electrical resistance across different system configurations.
