Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional panel installation structures require multiple fastening steps, leading to inefficient installation on roof surfaces due to the need for screwing bolts and screws, which reduces the overall efficiency of attaching support pieces, fixtures, and sash bars.
Innovation Solution
A trestle system with a fixing unit, receiving member, and base unit that allows for adjustable height fixation using a first fastener, which sandwiches and engages components to simplify the installation process, reducing the number of required fastening steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple fasteners (bolts and screws) are used to fix the sash bar material to the support piece, then the connection strength is improved, but the installation time and work complexity increase
Solution Approach 1:
The patent combines the functions of multiple fasteners into a single integrated fastening mechanism. The fixing unit integrates both the support piece fixing function and the sash bar material fixing function into one component that can be installed with a single fastening operation, eliminating the need for separate bolt and screw installation steps while maintaining connection strength.
Solution Approach 2:
The fixing unit is designed as a universal component that performs multiple functions: it fixes to the support piece, holds the sash bar material, and provides adjustment capability. This multi-functional design replaces the need for multiple specialized fasteners, reducing installation time while maintaining the required connection strength for different components.
2Reliability
If multiple fastening steps are required to attach support piece, fixture, and sash bar material, then the connection reliability is improved, but the productivity of installation work decreases
Solution Approach 1:
The patent merges the attachment of the support piece, fixture, and sash bar material into a single integrated fixing operation. The fixing unit is designed to simultaneously secure all these components in one installation step, maintaining connection reliability through integrated design while dramatically improving installation efficiency by eliminating multiple sequential fastening steps.
Solution Approach 2:
The fixing unit is pre-configured with the necessary structural features and engagement mechanisms before installation. The support piece, fixture, and sash bar material are designed with complementary features that enable single-step attachment, allowing the installer to simply position and secure the assembly without performing multiple separate fastening operations.
3Productivity
If a single fastener is used to fix the receiving member to the base unit, then the installation efficiency is improved, but the connection strength may be reduced
Solution Approach 1:
The single fastener is designed with segmented or multi-functional features that allow it to perform multiple fastening functions simultaneously. The fastener includes integrated elements that provide both anchoring to the base unit and securing of the receiving member, effectively distributing the connection load through strategically placed engagement points while maintaining the simplicity of a single fastening operation.
Solution Approach 2:
The fastener is designed as a composite structure combining different material properties or structural features within a single component. This allows the single fastener to achieve both high connection strength and installation efficiency by integrating features that provide secure anchoring, clamping force, and structural support in one element.

AI summary
A trestle includes a fixing unit for fixing a solar panel, a receiving member receiving the fixing unit from below, a base unit, and a first fastener. The base unit is formed with a height direction adjusting groove for fixing the receiving member to be adjustable in a height direction from a roof surface. The first fastener fixes the receiving member to the base unit by being attached to the height direction adjusting groove. The receiving member includes a sandwiching portion that sandwiches a part of the fixing unit and is formed with a hole into which the first fastener is inserted. The first fastener is formed in a shape attachable to the height direction adjusting groove and a shape insertable into the hole, and sandwiches a part of the fixing unit in the sandwiching portion.
