Hearse Interior Foil Decor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior fittings for hearses are not versatile or hygienic, and changes in the decor portfolio from suppliers can render repairs difficult, as specific surface elements may no longer be available for replacement.
Innovation Solution
The visible sides of surface elements are formed by glue-on foils that can be customized with digital printing, allowing the vehicle manufacturer to choose decors and ensuring seamless, easy-to-clean surfaces, even after extended use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-supplied surface elements with fixed decors are used, then the interior fitting process is simplified, but repairability deteriorates when decors are no longer available
Solution Approach 1:
The patent separates the surface element into two independent components: the base material (metal plate or sandwich panel) and the decorative foil. This segmentation allows the foil to be removed and replaced independently from the base material, enabling repair of the decor without replacing the entire surface element, thus resolving the contradiction between manufacturing simplicity and repairability.
Solution Approach 2:
The decorative foil is extracted as a separate, removable component from the surface element. The foil can be peeled off and replaced with a new foil having the same or different decor, while the base material remains in place. This extraction principle enables easy replacement of decors even when original decors are no longer available from suppliers.
2Strength
If sealed joints between surface elements are used, then structural integrity is improved, but cleanability deteriorates due to crevices
Solution Approach 1:
The patent uses a foil that extends continuously over the joints between surface elements, creating a seamless surface that eliminates crevices where dirt could accumulate. The foil acts as a flexible sealing layer that maintains joint integrity while providing a smooth, continuous surface that is easy to clean, thus resolving the contradiction between structural integrity and cleanability.
3Manufacturing precision
If sharp edges are used on surface elements, then manufacturing precision is improved, but foil application deteriorates due to tearing
Solution Approach 1:
The patent specifies that the edges of surface elements should be rounded rather than sharp. This curvature prevents the foil from being torn or damaged during application, as the rounded edges allow the foil to conform smoothly without stress concentration points. This resolves the contradiction by maintaining manufacturing precision while improving foil application ease.
