Automotive Transmission Touch Shift Panel Space Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automotive transmissions require significant space for gear shift operations, limiting vehicle interior space and potentially leading to erroneous operations due to the physical nature of gear shift levers.
Innovation Solution
An automotive transmission system that allows gear shift stage selection through touch operations using a plurality of touch buttons, enabling point touch and drag touch operations to select shift stages, with a controller determining the shift stage based on detected touch operations and pressure magnitude to prevent erroneous selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a floor type gear shift lever is used, then the gear shift operation can be performed, but the vehicle interior space is occupied and passenger movement is inconvenient
Solution Approach 1:
The patent replaces the mechanical floor type gear shift lever with a touch-sensitive panel that detects touch operations. The gear shift stage is selected by touching specific regions or buttons on the panel, eliminating the need for a physical lever and the space it occupies. The touch panel can be integrated into the dashboard or center console, freeing up floor space and improving passenger accessibility.
2Area of stationary object
If a touch operation unit is used for gear shift selection, then the space required is reduced, but erroneous operations may occur due to accidental touches
Solution Approach 1:
The touch-sensitive panel is divided into multiple distinct touch-sensitive regions, each corresponding to a specific gear shift stage. Each region has unique spatial coordinates or identification characteristics, allowing the control unit to precisely identify which region was touched. This localized differentiation ensures that only intentional touches of the correct region trigger a gear change, preventing erroneous operations from accidental touches in other areas.
Solution Approach 2:
The system provides visual feedback through illumination or display indicators showing which gear shift stage is currently selected or will be selected. This feedback mechanism allows the driver to confirm their intended action before the gear change occurs, preventing erroneous operations. The control unit processes touch operations and provides immediate visual confirmation, ensuring the driver's intent is correctly interpreted.
