Flush-Mounted Solar Panel Frame for Walkable Load-Bearing Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional solar panel frames are not designed for walkable surfaces and have limitations such as debris accumulation, safety risks from protruding edges, lack of load-bearing capacity, and complex installation methods unsuitable for pedestrian applications.
Innovation Solution
A novel frame profile with a cross-sectional design where the upper flange does not cover the glass surface, edge-finished light-transmissive layer edges, and a horizontal chamber for easy attachment, enhancing load-bearing capacity and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional frame-over-edge design is used, then structural support is provided, but debris accumulates on the protruding frame edges and sunlight is blocked
Solution Approach 1:
The patent inverts the traditional frame design by placing the frame underneath the light-transmissive layer instead of over it. The frame's upper surface is positioned below the lower surface of the light-transmissive layer, eliminating protruding edges where debris could accumulate while still providing structural support from below.
2Strength
If traditional frame-over-edge design is used, then structural support is provided, but the frame is prone to damage from foot traffic and lacks load-bearing capacity
Solution Approach 1:
By inverting the frame position to be underneath the light-transmissive layer, the design protects the frame from direct exposure to foot traffic and environmental damage. The frame remains structurally supportive while being shielded by the light-transmissive layer above.
Solution Approach 2:
The patent combines the frame with reinforcement elements to create a composite structure with enhanced load-bearing capacity. This composite design allows the frame to withstand heavy loads from pedestrians and maintenance equipment while maintaining its structural support function.
3Object-affected harmful factors
If flush-frame design is used, then debris accumulation is prevented and load-bearing capacity is enhanced, but manufacturing complexity increases
Solution Approach 1:
The inverted frame design simplifies the manufacturing process by eliminating the need for complex edge sealing and protection mechanisms required in traditional over-edge designs. The frame is positioned below the light-transmissive layer, allowing for simpler assembly and reduced manufacturing steps.

AI summary
The present invention relates to solar photovoltaic (PV) panels designed for integration into walkable surfaces. The novel frame profile 200 features a cross-sectional design where the upper flange 327 does not extend over the light-transmissive layer 310, preventing debris accumulation and reducing physical damage risks. Utilizing thicker light-transmitting layer 310, preferably 6-12 mm, with edge finishing 311, the upper flange 327 frame 200 sits flush with or below the upper surface of the light-transmitting layer 310. The clamping surface 324 on the edges of the assembly 20 allows for the use of commercially available decking mounting systems. This innovative design simplifies installation and enhances durability, rendering the panels suitable for a wide range of applications, including decks, rooftops, balconies, terraces, event spaces, and bridges.
