Shift Lever Positioning for Clear EV Readiness Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle transmission devices lack a straightforward method for drivers to easily recognize the vehicle's state, particularly in electric vehicles where engine status is not indicated by noise or vibration, making it difficult to determine if the vehicle is ready for operation.
Innovation Solution
A vehicle transmission device with a position-adjusting mechanism for the transmission operation unit, which changes its position based on the vehicle's state, enabling or disabling transmission operations and using a light emitting module to provide visual feedback about the vehicle's state and current transmission stage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the transmission operation unit remains stationary, then the structure is simple, but the driver cannot easily recognize the vehicle's state
Solution Approach 1:
The transmission operation unit is designed to dynamically change its position based on vehicle state. When the vehicle transitions between drive and neutral states, the operation unit automatically moves between different positions, providing visual feedback to the driver about the current vehicle state without requiring additional indicators.
Solution Approach 2:
The transmission operation unit serves dual functions: it operates as the transmission control interface and simultaneously serves as a vehicle state indicator. The unit's position itself communicates the vehicle state to the driver, eliminating the need for separate indicator systems.
2Loss of information
If a separate indicator system is added to show vehicle state, then vehicle state recognition is improved, but the device complexity increases
Solution Approach 1:
The transmission operation unit is designed to perform multiple functions: it controls transmission operations and simultaneously indicates vehicle state (drive/neutral/ignition status). This multi-functionality eliminates the need for separate indicator systems while providing comprehensive vehicle state information to the driver.
Solution Approach 2:
The indication function is merged with the transmission operation unit itself. The physical position and visual characteristics of the operation unit are combined with the vehicle state information, creating an integrated system that provides both control and feedback functions through a single component.

AI summary
A transmission device for a vehicle includes a vehicle state detector for detecting a vehicle state, a transmission operation unit for enabling a transmission operation of selecting one of a plurality of transmission stages, and a position adjusting unit for adjusting a position of the transmission operation unit based on the detected vehicle state to allow the transmission operation unit to slidingly move between a first position where a transmission operation is disabled and a second position where a transmission operation is enabled.
