Steering Wheel Switch Display for Multi-Function Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering switch devices struggle to efficiently manage multiple operation inputs, leading to degraded operational performance as users need to scan a wider area to find desired switches, making it difficult to assign and switch between three or more functions.
Innovation Solution
A steering switch device with displays on a steering wheel that show functions in a switching manner, combined with input units such as touch panels and switches, allowing users to execute functions by selecting them on a display without the need for multiple switches, thus maintaining operational performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple switches are arranged to assign three or more functions, then the number of operation inputs increases, but the area users need to scan widens so that operational performance degrades
Solution Approach 1:
A single switch is designed to perform multiple functions by switching between different operation inputs (first operation input and second operation input). The switch can determine which display state it has received an input in, enabling it to function as two operation inputs simultaneously. This multi-functionality allows the system to provide three or more functions without requiring multiple separate switches, thereby maintaining operational performance while increasing adaptability.
Solution Approach 2:
The switch incorporates a variable display structure that dynamically changes between different display states (first view and second view) by switching light projected onto a translucent sheet between light from a first light source and light from a second light source that have different wavelengths. This dynamic display allows users to see different functions at different times, enabling the single switch to convey multiple operation inputs without requiring the user to scan a wide area of multiple static switches.
2Ease of operation
If a single switch is used to display multiple functions, then the area users need to scan is reduced, but it becomes difficult to switch between three or more operation inputs
Solution Approach 1:
The patent adds a temporal dimension to the display by using different wavelengths of light to project different views at different times. The variable display structure switches between first view and second view by alternating light sources with different wavelengths, allowing multiple functions to be displayed sequentially rather than spatially. This enables a single switch to handle three or more operation inputs by presenting them in time rather than space, resolving the contradiction between maintaining operational performance and increasing adaptability.
