Solar Panel Frame Mounting with Pre-Fixed Riveted Nut Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar cell panel mounting systems require manual finger insertion for nut fixation, leading to increased material usage, longer leg lengths, and potential nut misplacement, complicating the mounting process and increasing costs.
Innovation Solution
A solar cell panel mounting structure featuring nut members with rivets and fixers that are integrally fixed to the frame, allowing for bolt coupling without finger insertion, reducing leg length and material usage, and enhancing mounting efficiency with washers for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual finger insertion is used for nut fixation, then the mounting process becomes complicated and time-consuming, but the nut members can be positioned and fixed
Solution Approach 1:
The nut members are pre-fixed to the frame using rivets before the mounting process. This preliminary fixation eliminates the need for manual finger insertion during installation, allowing workers to simply slide the panel onto the mounting stand and secure it with bolts, thereby improving mounting speed and reducing complexity
Solution Approach 2:
The rivet structure enables the nut members to self-fix to the frame without requiring manual intervention for positioning. The rivet passes through the leg and secures the nut member in place, allowing the system to self-assemble the fixation without human finger insertion, thus improving both productivity and ease of operation
2Stability of the object's composition
If longer leg lengths are used to accommodate manual fixation, then structural stability is improved, but material consumption and manufacturing costs increase
Solution Approach 1:
The rivet fixation is performed in advance during manufacturing, allowing the legs to be optimized for minimal length required for structural support rather than accommodating manual operation space. This separates the structural function from the operational function, enabling material reduction while maintaining stability
Solution Approach 2:
The fixation function is separated from the structural leg by introducing rivets as a distinct fixation mechanism. The leg only needs to provide structural support and contain holes for rivet passage, while the rivet handles the fixation task, allowing the leg length to be minimized for material efficiency without compromising structural integrity
3Loss of substance
If shorter leg lengths are used to reduce material usage, then manufacturing costs decrease, but the ability to manually fix nut members is compromised
Solution Approach 1:
The manual finger insertion mechanism is replaced with a rivet-based mechanical fixation system. The rivet provides a reliable mechanical connection between the nut member and the frame, eliminating the need for manual manipulation and allowing shorter leg lengths while maintaining ease of manufacture through automated or semi-automated riveting processes
Solution Approach 2:
The rivet structure enables automatic or semi-automatic fixation of nut members to the frame during manufacturing. The rivet passes through the leg and secures the nut member in place through deformation or interlocking, allowing the system to self-complete the fixation without requiring manual finger insertion, thus enabling shorter legs and reduced material consumption
4Adaptability or versatility
If nut members are not pre-fixed to the frame, then assembly flexibility is maintained, but nut misplacement and mounting errors occur
Solution Approach 1:
The nut members are pre-fixed to the frame at precise locations during manufacturing using rivets. This preliminary positioning ensures accurate alignment with the mounting stand holes, eliminating mounting errors while the modular panel design maintains assembly flexibility for different installation scenarios
Solution Approach 2:
The rivet acts as an intermediary that permanently secures the nut member to the frame, ensuring precise positioning and preventing misplacement. This intermediary fixation mechanism guarantees that the nut member remains in the correct position during transport and installation, improving reliability without compromising the overall assembly flexibility of the solar panel system
