Solar Frame Bracket Assembly for Tolerance Fit and Anti-Rubbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar device frame assemblies face challenges with varying assembly tolerances across different manufacturers, leading to delayed production schedules and potential damage from external forces causing the electronic component to rub against the solar panel.
Innovation Solution
A frame assembly with sliding grooves and engaging grooves, along with brackets featuring extended parts and block structures, increases the contact area between the bracket and frame, preventing loose attachment and maintaining distance between components to prevent rubbing, while allowing for assembly adjustments and enhanced structural resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electronic component is fixed directly on the frame using screws, then the assembly process is simple, but the assembly tolerance cannot accommodate different manufacturers' specifications and the electronic component is vulnerable to deformation damage
Solution Approach 1:
The patent introduces a bracket as an intermediary component between the frame and the electronic component. The bracket includes a sliding groove that receives the electronic component and an engaging groove that connects to the frame, serving as a mediator that accommodates tolerance variations and protects the electronic component from direct deformation forces.
Solution Approach 2:
The patent employs a sliding groove mechanism that allows the bracket to move dynamically relative to the frame. This dynamic connection enables the assembly to adjust to tolerance variations from different manufacturers while maintaining secure attachment, and provides deformation space to protect the electronic component.
2Ease of manufacture
If the bracket is loosely attached to the frame, then the assembly is easy to manufacture, but the bracket may loose or come off during operation
Solution Approach 1:
The patent transitions from a single-point screw attachment to a multi-dimensional engagement system. The engaging groove provides lateral constraint while the sliding groove provides longitudinal adjustment, creating a stable attachment that prevents the bracket from loosening or detaching during operation.
Solution Approach 2:
The patent divides the attachment function into two separate groove structures: an engaging groove for secure lateral attachment and a sliding groove for longitudinal positioning and adjustment. This segmentation allows the bracket to be firmly attached while maintaining ease of assembly and adjustment.
3Device complexity
If the electronic component is positioned close to the solar panel, then the device structure is compact, but the component may rub against the solar panel when the device deforms due to external force
Solution Approach 1:
The patent provides predetermined deformation space through the sliding groove mechanism before any harmful rubbing can occur. When external forces cause device deformation, the bracket can move within the sliding groove to absorb the deformation, preventing the electronic component from rubbing against the solar panel.
4Adaptability or versatility
If different frames and electronic components are manufactured with different assembly tolerances to satisfy each manufacturer's requirements, then the assembly compatibility is improved, but the production schedule is delayed
Solution Approach 1:
The patent designs the bracket with universal engagement features that can accommodate tolerance variations from different manufacturers. The sliding groove and engaging groove configuration provides a universal attachment mechanism that works with various frame and electronic component specifications, eliminating the need for manufacturer-specific custom parts and streamlining production.

AI summary
A frame assembly including a frame and a bracket is disclosed. The frame has a sliding groove and a first engaging groove, wherein the sliding groove is formed at one side of the frame and the first engaging groove is formed in the sliding groove. The bracket has a body and a first engaging part, wherein the first engaging part is extended from the body. When the body is disposed in the sliding groove, the first engaging part is engaged in the first engaging groove.
