Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic gear shift levers lack effective means to prevent erroneous gear shift manipulations, particularly for inexperienced drivers, leading to potential accidents during changes between Reverse (R)-stage/Drive (D)-stage and Park (P)-stage/Neutral (N)-stage, due to lack of clear feedback on gear shift signals.
Innovation Solution
A motion demonstration electronic gear shift apparatus that includes a movable device and controller system, which moves a demonstration device to indicate the intended gear shift direction before the gear change occurs, providing visual and tactile feedback to the driver, and integrates with the vehicle's transmission control unit to ensure accurate gear shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple beep sound is used for gear shift indication, then the device complexity is reduced, but the reliability of gear shift signal recognition deteriorates
Solution Approach 1:
The patent introduces a motion demonstration device as an intermediary between the gear shift lever operation and the actual gear shift execution. This device physically demonstrates the gear shift direction (forward for D-stage, backward for R-stage) before the gear shift occurs, providing clear visual and tactile feedback to prevent erroneous operations without requiring complex electronic systems
Solution Approach 2:
The motion demonstration device performs a preliminary action by moving in the direction of the intended gear shift before the actual gear shift takes place. This preliminary demonstration allows the driver to confirm the correct operation, preventing erroneous gear shifts while maintaining simple device structure
2Ease of operation
If no motion demonstration is provided, then the ease of operation is improved, but the reliability of preventing erroneous gear shift manipulation deteriorates
Solution Approach 1:
The motion demonstration device serves as an intermediary that provides tactile and visual feedback during gear shift operation. It moves in sync with the gear shift lever and demonstrates the intended direction before execution, enhancing reliability without complicating the operation
Solution Approach 2:
The system implements feedback by providing real-time motion demonstration that reflects the driver's input. The demonstration device moves forward for D-stage and backward for R-stage, giving immediate feedback to confirm correct operation before the gear shift is executed
3Reliability
If a motion demonstration device is added to show gear shift direction, then the reliability of gear shift recognition is improved, but the device complexity increases
Solution Approach 1:
The motion demonstration device is a simple mechanical intermediary that connects to the gear shift lever mechanism. It demonstrates gear shift direction through physical motion without requiring complex electronics, sensors, or control systems, thus improving reliability while adding minimal complexity
Solution Approach 2:
The motion demonstration device creates a simplified copy of the gear shift action. It replicates the motion of the gear shift lever in a visible and tactile manner, allowing drivers to recognize the intended gear shift stage without complex display systems

AI summary
A motion demonstration electronic gear shift apparatus may include a motion demonstration device having a gear shift stage selection device configured to change a gear shift stage of a vehicle, and movably mounted in the vehicle, a controller configured to recognize an operation of the gear shift stage selection device to move the motion demonstration device, and to transmit a signal generated by the gear shift stage selection device to a transmission control unit (TCU) of the vehicle to change the gear shift stage, and a movable device configured to move the motion demonstration device forward and rearward by receiving a signal from the controller.
