Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for folding edges of trim parts often result in the formation of bumps due to poor material control, leading to material wastage and increased costs.
Innovation Solution
A method involving the use of a heat source and a blade, where a folder tool is used to laterally and then vertically fold the substrate's edge, with a backup blade providing support and a heat emitter enhancing the folding process for precise results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional folding methods are used, then the process is simple, but bumps are formed due to poor material control
Solution Approach 1:
The folding process is divided into multiple sequential steps: heating the substrate, positioning the backup blade, applying lateral folding force, then applying vertical folding force. This segmentation allows each step to be optimized independently, improving precision without overwhelming complexity
Solution Approach 2:
The substrate is heated before folding to prepare the material for deformation. This preliminary action modifies the material properties in advance, making it more pliable and easier to fold without forming bumps, thereby improving precision
2Loss of substance
If conventional folding methods are used, then the process is fast, but material wastage increases due to poor control
Solution Approach 1:
The use of a backup blade provides tactile feedback and physical support during the folding process, allowing operators to sense material behavior and adjust forces accordingly. This feedback mechanism prevents poor control and material wastage while maintaining efficient production
Solution Approach 2:
Heating the substrate changes its physical parameters (temperature, flexibility), making it more amenable to folding. This parameter change reduces material resistance to folding, improving control and reducing wastage without significantly impacting production speed
3Manufacturing precision
If heating is applied to the substrate, then folding precision improves, but energy consumption increases
Solution Approach 1:
Rather than heating the entire substrate uniformly or excessively, the process applies heat selectively to the area requiring folding. This partial action achieves the necessary precision while minimizing overall energy consumption

AI summary
A method of folding edges of trim parts includes the following steps. Place an inner surface of a substrate against a panel support so that an upper end of the substrate is disposed above a top end of the panel support. Press a backup blade against an outer surface of the substrate beneath the upper end of the substrate. A folder tool of an edge folding apparatus is urged against the inner surface of the upper end of the substrate in a horizontal direction which laterally folds the upper end 96 of the substrate. Remove the backup blade from the outer surface of the substrate. Then urge the folder tool of the edge folding apparatus against the inner surface of the substrate in a vertical direction and downwardly folding the upper end 96 of the substrate.
