Vehicle Shift Indicator Dynamic Size Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices for vehicle shift positions are often displayed in smaller sizes and lower densities, making it difficult for drivers to easily recognize changes in the shift position during driving.
Innovation Solution
A display device that gradually enlarges and then reduces the size and density of the shift position indicator, starting from a smaller size and lower density, to draw attention to the current shift position, ensuring the driver can easily identify changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display element size is kept small to maintain screen layout, then the screen can accommodate more information, but the driver has difficulty finding and recognizing the shift position display element
Solution Approach 1:
The display element dynamically changes its size based on the operational state. When a shift position change is detected, the display element automatically enlarges to draw the driver's attention, then returns to its normal smaller size after a predetermined time period. This dynamic size adjustment resolves the contradiction by making the display element large only when necessary for recognition.
Solution Approach 2:
The display element undergoes periodic size changes triggered by shift position changes. Each time the shift lever is operated, the display element enlarges for a predetermined duration and then returns to its normal size. This periodic enlargement pattern ensures the driver notices the shift position change without permanently increasing the display element size.
2Difficulty of detecting and measuring
If the display element size is increased to improve visibility, then the driver can easily recognize the shift position, but the screen space for other display elements is reduced
Solution Approach 1:
The display element size is dynamically adjusted based on operational needs rather than being permanently enlarged. The element maintains its normal small size during normal operation, preserving screen space, and temporarily enlarges only when a shift position change occurs, providing visibility when needed without sacrificing overall screen real estate.
Solution Approach 2:
The enlargement of the display element occurs periodically only when shift position changes are detected, lasting for a predetermined time period. This periodic action ensures that the display element is large and visible only when necessary, while maintaining normal small size otherwise, thus balancing visibility requirements with screen space constraints.
3Device complexity
If conventional display elements are used without size changes, then the display is simple and stable, but the driver cannot easily notice changes in shift position
Solution Approach 1:
The display system incorporates dynamic size adjustment functionality that activates automatically when shift position changes are detected. This adds minimal complexity to the control system while significantly improving change detection capability, as the enlargement of the display element naturally draws the driver's attention to the shift position change.
Solution Approach 2:
The system implements feedback by detecting shift lever position changes and automatically responding with display element enlargement. This feedback mechanism creates a direct link between the physical shift operation and the visual display response, ensuring the driver immediately notices the shift position change without requiring complex additional controls.

AI summary
A display section displays a shift indicator in a smaller size than that in a normal state at the start of display (upon switching the display) of the shift indicator. After that, the display section gradually enlarges a size of the shift indicator until it has a larger size than that in the normal state, and then gradually reduces the size of the shift indicator until it has the size in the normal state, thereby starting the display of the shift indicator in the size in the normal state. This operation provides a display device through which a driver can readily recognize the current shift position.
