Articulating solar panel mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar array installations are limited by International Fire Code (IFC) setbacks and maintenance access requirements, leading to significant unused roof space, as solar panels cannot be placed in areas reserved for maintenance accessibility and fire protection, reducing the potential number of solar panels that can be utilized on a roof.
Innovation Solution
An articulating solar panel mount with a lower frame affixed to the roof and a pivotable upper frame, actuated by a biasing mechanism and releasable latch mechanism, allowing the upper frame to open and providing access for maintenance and inspection without removing the solar panel, thus maximizing roof space usage while adhering to code requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If solar panels are placed in code-mandated setback areas, then the number of solar panels that can be installed increases, but compliance with fire code requirements for maintenance accessibility is violated
Solution Approach 1:
The solar panel mounting system employs an articulating mount that can dynamically change its configuration between a closed position (when not in use) and an open position (when maintenance is needed). This dynamic capability allows the system to comply with fire code setback requirements during normal operation while still enabling access to the underside of solar panels when maintenance personnel need to work in previously restricted areas.
Solution Approach 2:
The system changes the spatial parameter of the mounting structure by articulating between different angular positions. The mount can be positioned at various angles to provide clearance for maintenance access while maintaining solar panel installation in areas that would otherwise be restricted by code-mandated setbacks, effectively changing the geometric parameters to satisfy both energy production and safety requirements.
2Reliability
If maintenance access pathways are maintained according to IFC requirements, then compliance with fire codes is ensured, but the available roof space for solar panel installation is reduced
Solution Approach 1:
Instead of maintaining permanent open pathways, the system uses dynamic articulating mounts that can open temporarily when maintenance is needed and close when not in use. This eliminates the need for permanent setbacks, allowing solar panels to be installed in areas that would otherwise be reserved for maintenance access, thereby maximizing roof space utilization while ensuring compliance with fire codes.
Solution Approach 2:
The articulating mount provides maintenance access by moving in the vertical dimension (articulating upward to create clearance) rather than requiring horizontal setback space. This dimensional change allows the system to provide necessary maintenance access without consuming valuable horizontal roof space that could be used for solar panel installation.
3Area of stationary object
If the upper frame is kept closed to maximize solar panel placement, then roof space utilization is improved, but access to the underside of solar panels for maintenance becomes difficult
Solution Approach 1:
The articulating mount allows the upper frame to be opened on-demand when maintenance personnel need to access the underside of solar panels. The frame can articulate upward to create sufficient clearance for inspection and maintenance activities, then return to a closed position to maximize space utilization. This dynamic capability eliminates the need to choose between space optimization and maintenance accessibility.
Solution Approach 2:
The biasing mechanism automatically returns the upper frame to its closed position after maintenance activities are complete, eliminating the need for manual repositioning. The system self-regulates between open and closed states based on operational needs, with the biasing mechanism providing the restoring force to maximize space utilization during normal operation.
4Ease of operation
If a biasing mechanism is added to automatically open the upper frame, then maintenance access is improved, but device complexity increases
Solution Approach 1:
The biasing mechanism is a passive component that automatically provides the opening force without requiring external power sources, control systems, or complex actuation mechanisms. It simply uses mechanical biasing (such as springs or elastic elements) to return the frame to its open position, providing maintenance access functionality while adding minimal complexity to the overall system.

Function Achieved in This Case
The articulating mount allows for increased solar panel placement on roofs while maintaining accessibility, enabling efficient use of previously unused space and simplifying maintenance and inspection processes, thereby enhancing solar capacity and compliance with building and fire codes.
Implementation Method 1
a biasing mechanism such as a gas spring or strut is secured to the lower frame at a first end and to the upper frame at a second end, and is positioned to normally bias the distal end of the upper frame away from the lower frame toward the open position

AI summary
An articulating solar panel mount comprising a slim profile lower frame that rests on and is affixable to a roof, and a spring-actuated upper frame that is hinged on one side. A solar panel may be attached to the topside of the hinged frame. The mount includes an indexable latching mechanism comprising a reversible quick release that can be adjusted to be accessed from either direction depending on installation needs. The latching release mechanism is designed to allow for “daisy chaining” multiple frames in succession, which allows for creation of a walkway/path through the solar array. The hinged solar frame may be over sprung to self-open, accounting for the weight of the solar panel and the frame itself.
