Sliding Nut Constraint Mechanism for Adjustable Channel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solar panel mounting systems face issues such as exposed and unsecured struts, costly manufacturing, brittle material usage, high failure rates, and inadequate handling of component misalignment during installation.
Innovation Solution
The system incorporates an end cap with nut-shaped slots and flexible fingers that prevent the sliding nut from escaping the channel, allowing adjustable positioning along the bar, ensuring secure and flexible mounting of coupling devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sliding nut is allowed to move freely in the channel, then the installer can choose any desirable location for mounting, but the nut may escape the channel or enter the no-go-zone at the end
Solution Approach 1:
The patent uses a flexible finger made of resilient material that protrudes into the channel to constrain the sliding nut. The flexibility allows the finger to deform under load while maintaining its constraining function, preventing the nut from escaping the channel or entering the no-go-zone while still allowing adjustable positioning.
Solution Approach 2:
The patent changes the physical state of the constraint mechanism from rigid to resilient. The flexible finger's material properties allow it to dynamically adjust its constraint force based on the nut's position and applied loads, maintaining reliability across different installation scenarios.
2Strength
If common struts are used for mounting, then the structure provides support, but they are costly, use excessive material, and are manufactured from brittle materials with higher failure rates
Solution Approach 1:
The patent divides the mounting system into separate functional components: the bar with channels for positioning, the sliding nut for adjustable mounting, and the flexible finger for constraint. This segmentation allows each component to be optimized independently, using less material while maintaining strength.
Solution Approach 2:
The patent employs resilient materials for the flexible finger and bar, replacing traditional brittle materials. This material substitution reduces manufacturing costs and failure rates while maintaining or improving structural support capabilities.
3Ease of manufacture
If nuts are forced into predetermined designated positions, then manufacturing is simplified, but the installer cannot optimize the mounting location for each specific application
Solution Approach 1:
The patent transforms the mounting system from static predetermined positions to a dynamic adjustable system. The sliding nut can be positioned anywhere along the channel within the constrained range, allowing optimization for each specific application while maintaining manufacturing simplicity through the use of standard channels and nuts.

Function Achieved in This Case
This solution provides a cost-effective, secure, and adaptable mounting system that optimizes material usage and prevents misalignment issues, allowing for flexible nut positioning and reducing failure rates.
Implementation Method 1
The end cap further includes a flexible finger that protrudes into each channel of the bar at a desirable distance such that the sliding nut may not reach the end of the channel

AI summary
A system to prevent a sliding nut in a channel in a bar from escaping from the channel, and to prevent the nut from entering a no-go-zone at the end of the channel. The system is adjustable to position the nut at a desirable location along the length of the channels to mount coupling devices onto the bar.
