Smart Touch Auto-Shift Lever Reducing Interior Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic auto-shift levers are inflexible, occupy excessive space, and fail to adapt to user preferences, as they are fixed with a constant linear shape, making them less appealing to users accustomed to mechanical shift levers and limiting interior vehicle space.
Innovation Solution
A smart touch type electronic auto-shift lever with a touch screen that allows users to vary shift patterns, sizes, and locations through input on a console-connected shift stage controller, enabling customizable shift operations and reducing physical space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional mechanical shift lever is used, then the shift operation is familiar to users, but the vehicle interior space is excessively occupied
Solution Approach 1:
The patent replaces the traditional mechanical shift lever with a touch screen interface that displays virtual shift pattern. The touch screen receives touch inputs from users and transmits shift commands to the transmission control unit, eliminating the need for physical lever movement while maintaining shift control functionality.
Solution Approach 2:
The patent creates a virtual copy of the mechanical shift lever operation through a touch screen interface. The shift pattern is displayed as virtual elements (P, R, N, D, etc.) that users can touch, replicating the familiar shift selection process without requiring physical space for a mechanical lever.
2Device complexity
If a fixed linear shift pattern is used, then the device structure is simple, but the adaptability to user preferences is poor
Solution Approach 1:
The patent implements a dynamic shift pattern where the arrangement of shift elements (P, R, N, D, etc.) can be changed based on user preferences. The system allows users to customize the shift pattern configuration, making the previously static linear arrangement adaptable and flexible while maintaining simple device structure.
3Measurement precision
If a traditional electronic shift lever is used, then the shift control is precise, but the operational sense is less appealing compared to mechanical levers
Solution Approach 1:
The patent replaces the mechanical shift lever with a touch screen interface that provides both the precision of electronic control and the visual appeal of a modern interface. The touch screen displays a virtual shift pattern that gives users visual feedback and tactile interaction, combining electronic precision with enhanced operational sense.
4Volume of moving object
If a touch screen interface is implemented, then the vehicle interior space is optimized, but the shift pattern customization complexity increases
Solution Approach 1:
The touch screen interface serves multiple functions: displaying the shift pattern, receiving user inputs for shift selection, and enabling customization of the shift pattern arrangement. This multi-functionality consolidates what would otherwise require separate controls into a single interface, optimizing space while managing complexity through integration.
Data Source
AI summary
A smart touch type electronic auto-shift lever may include a shift stage controller which is connected to a controller of an electronic auto-transmission of a vehicle and a touch screen which is arranged on a console of a vehicle and is connected to the shift stage controller to display information of a shift pattern received from the shift stage controller and transmit input information produced by a touch to the shift stage controller. The shift stage controller generates the information of the shift pattern including the shift pattern and transmits it to the touch screen, and generates stage shift information allotted to the input information received from the touch screen and transmits it to the controller of the electronic auto-transmission of the vehicle.
