Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in motor vehicles face challenges in integrating additional functionalities, such as cable management and component fixing, without increasing bulk or compromising mechanical integrity, especially when the display is curved.
Innovation Solution
A display device comprising a partially transparent sheet and a structural component with a rear part and a front part that extends to frame the sheet, featuring openings for cable passage and fixing zones, allowing for adhesive filling and integration of additional components, while maintaining a smooth, stress-free surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the structural component is solid without openings, then mechanical integrity is improved, but cable management and component fixing become difficult
Solution Approach 1:
The structural component is segmented by introducing openings (passages) through its wall, dividing it into regions that serve different functions. These openings allow cables to pass through and provide mounting locations for components, while the remaining solid portions maintain structural integrity.
Solution Approach 2:
The openings in the structural component serve multiple functions simultaneously: they act as passages for cable routing, provide mounting holes for fixing components, and maintain aesthetic appearance when covered by the transparent sheet. This multi-functionality resolves the contradiction between structural integrity and adaptability.
2Adaptability or versatility
If additional functionalities are added to the structural component, then adaptability is improved, but device complexity increases
Solution Approach 1:
The structural component is designed with openings that simultaneously serve multiple purposes: cable passages, component mounting locations, and aesthetic features. This multi-functional design adds adaptability without requiring separate dedicated structures for each function, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The patent combines multiple functions (cable routing, component fixing, structural support, and aesthetic appearance) into a single integrated structural component design. By merging these functions into one component with strategically placed openings, the design avoids the complexity that would arise from adding separate components for each function.
3Shape
If the transparent sheet is curved, then aesthetic appearance is improved, but mechanical stress increases
Solution Approach 1:
The structural component is designed with rounded connecting surfaces at the interfaces where the transparent sheet is bonded. These rounded surfaces prevent stress concentration that would occur with sharp corners, thereby cushioning the sheet against mechanical stress while maintaining the desired curved shape.
Solution Approach 2:
The patent applies curvature to the connecting surfaces between the structural component and the transparent sheet, replacing sharp angular transitions with rounded or curved interfaces. This spheroidality principle reduces stress concentration points and distributes mechanical stress more evenly across the curved sheet.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables efficient cable management and component fixing without bulk, enhances mechanical integrity, and provides design flexibility, particularly for curved displays, by using adhesive and intermediate components to support the sheet and display.
Implementation Method 1
A coat of adhesive (or resin) is then interposed between the sheet and the front face.
