Retrofittable Panel Board Bracket Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting existing panel boards with new electrical components often requires costly and cumbersome processes, such as shimming or fabricating risers to align physically mismatched components, and involves unnecessary wall repairs when replacing the enclosure.
Innovation Solution
A retrofittable panel board kit comprising a bracket assembly with adjustable guide tracks and a mount assembly that allows for adjustable height and depth positioning of the interior assembly, ensuring registration with existing access openings without the need for new enclosures, thereby avoiding costly wall repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing panel board enclosure is replaced with a new enclosure to accommodate updated electrical components, then the electrical functionality can be updated, but wall repairs are required and costs increase
Solution Approach 1:
The invention separates the enclosure replacement need from the interior assembly replacement need. The interior assembly is made a独立的可更换模块，允许用户仅更换内部电气组件而保留现有 enclosure，从而避免昂贵的墙体维修工作
Solution Approach 2:
The invention introduces an intermediary mounting system (track assembly with adjustable brackets) between the existing enclosure and the new interior assembly. This intermediary mechanism enables adaptation to different component configurations while maintaining compatibility with the original enclosure
2Manufacturing precision
If shimming or fabricating risers is done to align physically mismatched components, then component alignment can be achieved, but the process becomes time-consuming and complex
Solution Approach 1:
The invention replaces static alignment methods (fixed shims or risers) with a dynamic adjustable mounting system. The track assembly allows the interior assembly to be positioned at multiple heights and locations, enabling precise alignment with access openings through simple adjustment rather than time-consuming custom fabrication
Solution Approach 2:
The invention changes the alignment parameter from fixed dimensional matching to adjustable positional configuration. By providing multiple predetermined positions on the track assembly, the system allows alignment to be achieved by selecting and adjusting to the appropriate position rather than through precise fabrication of alignment components
3Ease of operation
If a fixed mounting system is used for interior assemblies, then installation is simple, but adaptability to different component configurations is limited
Solution Approach 1:
The track assembly is designed as a universal mounting system that can accommodate multiple different interior assembly configurations. The adjustable brackets and multiple predetermined positions enable the same mounting system to work with various component types, sizes, and arrangements, providing both simplicity and flexibility

AI summary
A retrofittable panel board (8) for an electric apparatus is provided. A bracket assembly (10) is affixed to a backwall (1004) of an enclosure (1002) of the panel board. Bracket assembly (10) includes guide tracks (12) defining restraint locations (14) to provide an adjustable height. A mount assembly (50), providing mounting support to an interior assembly (13) and in turn to circuit breakers 18, is movable by way of the guide tracks with respect to the bracket assembly. An affixing element (16) is disposed in each guide track and connected to the mount assembly. When loosened, affixing element 16 may be arranged to travel connected with the mount assembly along the guide track to a desired restraint location. When tightened, affixing element 16 may be arranged to fixedly secure the mount assembly to the bracket assembly at the desired restraint location to provide a desired height position to the mount assembly with respect to the backwall of the enclosure.
