Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window pane arrangements in vehicle bodies face challenges in easy installation and accommodating tolerances between the glass pane and vehicle body components, leading to gaps and potential sealing issues.
Innovation Solution
A profiled frame component with multiple layers, comprising a hard material layer for contact elements and adhesive application, and a soft material layer with protrusions to cover the hard layer and contact other components, allowing for precise alignment and sealing, while reducing material usage and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer profiled frame component is used, then the structure is simple, but it cannot effectively cover gaps and tolerances between the glass pane and vehicle body components
Solution Approach 1:
The profiled frame component is divided into multiple layers: a hard material layer providing structural support and contact elements for adhesive bonding, and a soft material layer with projections that protrude over the hard layer to contact other components and accommodate tolerances. This segmentation allows each layer to perform its specific function effectively.
Solution Approach 2:
The profiled frame component combines hard material and soft material in a composite structure. The hard material provides rigidity and bonding capability, while the soft material provides flexibility and tolerance compensation. This composite approach resolves the contradiction between structural simplicity and effective gap coverage.
2Reliability
If the profiled frame component has multiple layers with protrusions, then it can cover gaps and tolerances effectively, but the device complexity increases
Solution Approach 1:
Multiple functional elements are merged into a single profiled frame component: the hard layer with contact elements for adhesive bonding, the soft layer with projections for tolerance compensation, and the integrated structure that combines both functionalities. This merging reduces the number of separate parts while maintaining complex functionality.
3Strength
If contact elements with large application surfaces are used, then adhesive bonding is stronger, but more material is consumed
Solution Approach 1:
The contact elements in the hard layer are designed with application surfaces for adhesive at specific locations where bonding is needed, rather than covering the entire surface. This localized approach provides sufficient bonding strength while minimizing material consumption. The soft layer projections are also strategically positioned to contact only where tolerance compensation is required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easier installation of glass panes by providing a secure, undetachable bond with the pane and vehicle body, effectively covering gaps and tolerances, and offering a durable, aesthetically pleasing solution with reduced material consumption.
Implementation Method 1
Contact elements are also provided in this hard layer. These contact elements of the hard layer of the profiled frame component are joined with the pane of glass.
Implementation Method 2
The protrusion over the hard layer allows the soft layer to come into contact with other components as well. For example, another component is the pane of glass, so that a projection of the soft layer protruding over the hard layer is brought into contact with the pane of glass, and can provide an offset for arising tolerances.
