Solution Overview
Problem
Button-type electronic gear shift levers in vehicles are prone to user error due to mal-operation, such as erroneous button presses or simultaneous button activations, leading to potential instability during gear shifting.
Innovation Solution
A transmission system with button portions incorporating light emitting portions that indicate the current and selectable gear shift stages through different brightness levels or colors, guided by a gear shift condition determination unit and controller to prevent mal-operation and ensure stable gear shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button-type electronic gear shift lever is used to select gear shift stages, then the ease of operation is improved, but the reliability deteriorates due to high possibility of mal-operation
Solution Approach 1:
The patent implements a feedback mechanism where the control unit receives signals from the detection unit about which button is pressed, determines whether the operation is valid based on current gear shift stage and vehicle state, and provides visual feedback through the light emitting portion to guide the driver. This closed-loop feedback system prevents mal-operation by validating each button press against current system state.
Solution Approach 2:
The patent uses the light emitting portion to indicate in advance which gear shift stages are selectable from the current stage before the driver actually presses a button. This preliminary indication allows the driver to verify the intended operation before execution, preventing erroneous button presses.
2Adaptability or versatility
If multiple buttons are provided to select multiple gear shift stages, then the adaptability is improved, but the difficulty of detecting and measuring increases due to potential simultaneous button operation
Solution Approach 1:
The detection unit detects which specific button is pressed and the control unit processes this information to determine the appropriate gear shift stage. The system provides feedback through the light emitting portion to confirm the detected button press and intended operation, making the detection process transparent and verifiable.
Solution Approach 2:
The control unit acts as an intermediary between the multiple buttons and the gear shift execution mechanism. It receives signals from any button, validates the operation against current system state, determines the correct gear shift stage, and executes the appropriate command, thereby simplifying the detection and measurement process.
3Device complexity
If no guidance is provided for selectable gear shift stages, then the device complexity is reduced, but the ease of operation deteriorates due to lack of driver guidance
Solution Approach 1:
The patent uses the light emitting portion to provide visual guidance to the driver about which gear shift stages are selectable from the current stage. Different light patterns or intensities can indicate different states, making the system intuitive to use without adding complex mechanical guidance mechanisms.
Solution Approach 2:
The light emitting portion serves as an intermediary communication channel between the control system and the driver. It translates the complex internal state of the transmission system into simple visual cues that guide the driver's button selection, improving ease of operation without adding mechanical complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents driver mal-operation by clearly indicating selectable gear shift stages based on vehicle conditions, improving vehicle stability by automatically shifting to a preset gear stage when mal-operation occurs.

Data Source
AI summary
A transmission for a vehicle is provided and includes a plurality of button portions that each include a button and a light emitting portion and the button is pushed to select a gear shift stage. The light emitting portion includes a light source. A gear shift condition determination unit determines gear shift conditions. Additionally, a controller is configured to determine a current gear shift stage and a selectable gear shift stage that corresponds to the gear shift conditions. The controller further turns on the light source included in the light emitting portion included in the button portions that corresponds to the current shift gear shift stage and the selectable gear shift stage. The light emitting portion that corresponds to the current gear shift stage and the light emitting portion that corresponds to the selectable gear shift stage are configured to emit light having different brightness levels or different colors.
