Universal Screen Module With Integrated Control Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing man/machine interfaces for motor vehicles, featuring multifunction screens, face limitations in design flexibility due to rectangular screen contours and high manufacturing costs, especially when producing low volumes of vehicle-specific models.
Innovation Solution
The method involves providing each screen module with its own control means, including a connector and microcontroller, allowing the same screen module to be used across different interfaces with varying designs and integrations, reducing the need for adaptation and lowering production costs by integrating control panels and indicators within a single housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the same screen module is used across different human-machine interfaces, then manufacturing cost is reduced, but the control means must be adapted for each interface which increases device complexity
Solution Approach 1:
The system is divided into independent modules: a universal screen module with its own integrated control means (microcontroller and connector), and separate interface-specific control panels. This segmentation allows the screen module to be reused across different interfaces without adaptation, while each interface maintains its own customized control panel for specific functions.
Solution Approach 2:
The screen module is designed as a universal component that can be used across multiple different human-machine interfaces. By integrating the control means (microcontroller and connector) directly into the screen module, it becomes a self-contained unit that does not require adaptation when used with different control panels or interfaces,从而实现多功能性。
2Ease of manufacture
If rectangular screen contours are used, then manufacturing is simplified, but design flexibility of dashboard is limited
Solution Approach 1:
The solution moves from modifying the screen's physical shape to modifying the opening contour in the housing. The screen module itself remains rectangular for easy manufacturing, but the housing opening can be shaped in various ways (curved, angular, organic shapes) to achieve diverse dashboard designs without complicating screen production.
3Ease of manufacture
If control means are integrated into the screen module, then adaptation cost is reduced, but screen module complexity increases
Solution Approach 1:
The control means (microcontroller and connector) are merged with the screen module to form an integrated unit. This combination eliminates the need for separate adaptation of control means when using the screen module with different interfaces, reducing adaptation costs despite the increased internal complexity of the screen module.
