Solution Overview
Problem
Conventional solar panel installation systems require expensive rails and multiple tools, leading to high labor costs and potential loosening of fasteners due to vibrations, necessitating frequent maintenance.
Innovation Solution
A clamp assembly with a cam-actuated self-locking mechanism that clamps onto the bottom flange of solar panels, eliminating the need for rails and allowing secure, tool-efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional solar panel installation systems use rails and multiple fasteners, then the solar panels can be securely mounted, but the installation cost increases and labor time increases
Solution Approach 1:
The clamp assembly is divided into distinct functional segments: a clamp body with teeth for gripping the solar panel frame, a cam mechanism for actuation, and a lever for operation. This segmentation allows each component to be optimized independently while working together as an integrated unit, eliminating the need for multiple separate fasteners and rails
Solution Approach 2:
The cam mechanism provides self-locking functionality where the cam wedge automatically maintains clamping pressure on the solar panel frame without requiring additional fasteners or continuous adjustment. The geometry of the cam surface creates a self-sustaining clamping force that resists loosening from vibrations, eliminating the need for multiple maintenance interventions
2Reliability
If conventional systems use multiple fasteners and rails, then solar panels can be attached, but fasteners loosen due to vibrations requiring frequent maintenance
Solution Approach 1:
The cam mechanism converts the harmful effect of vibrations into a beneficial self-tightening effect. As vibrations occur, the cam wedge geometry causes the clamp to automatically adjust and maintain optimal clamping pressure, transforming what would be a loosening force into a tightening force that enhances the durability and extends the maintenance interval
3Reliability
If conventional installation methods use expensive rails and multiple tools, then solar panels can be mounted securely, but installation costs increase
Solution Approach 1:
The invention extracts and eliminates the expensive rail system from the mounting assembly, replacing it with a standalone clamp that directly attaches to the solar panel frame. This extraction removes the need for separate rails, multiple fasteners, and specialized installation tools, significantly reducing material and labor costs while maintaining secure mounting through the integrated cam-actuated clamp mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamp assembly provides secure, universal, and vibration-resistant attachment of solar panels, reducing installation costs and maintenance needs.
Implementation Method 1
The lever portion comprises a cam. The cam comprises a rounded surface and a flat surface. Upon rotation of the lever portion from a position in which the rounded surface of the cam rotates along the bottom of a support portion to a position in which the flat surface of the cam locks against the bottom of the support portion, the cam urges the clamp portion into a clamped condition

AI summary
Clamp assemblies and systems for mounting solar panels to mounting units are presented. For instance, a clamp assembly for clamping a solar panel includes a clamp portion and a lever portion. The clamp portion includes at least one tooth for clamping onto a first flange of the solar panel. The lever portion is spaced apart from the clamp portion and includes a cam a. The cam includes a rounded surface and a flat surface. Each of the clamp portion and the lever portion comprise an opening for receiving a pivoting element. The opening is generally aligned when the clamp portion and the lever portion are fitted together. Upon rotation of the lever portion, the cam urges the clamp portion into a clamped condition.
