Motorcycle Display Interface for Quick Menu Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display systems in straddled vehicles require excessive operations to navigate between menu and vehicle characteristics settings, leading to reduced usability due to the need for frequent physical switch operations and cursor movements.
Innovation Solution
A display system with a communication unit connected to a portable terminal, allowing mode switching between main and launcher display modes via a handle switch, where icons are displayed side by side with a back button, enabling quick layer changes and mode transitions with minimal operations, eliminating the need for a physical back button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rider operates physical switches many times to navigate menu and change settings, then the settings can be changed, but the number of operations becomes large and usability deteriorates
Solution Approach 1:
The system stores the previously selected icon position in memory and automatically restores it when returning from vehicle characteristics screen to menu screen. This preliminary action of saving and restoring position eliminates the need for the rider to manually navigate back through multiple switches, reducing operation count and improving usability
Solution Approach 2:
The system creates a copy of the menu screen display position information and uses it to automatically position the cursor when returning to the menu. Instead of requiring the rider to physically navigate back through the same path, the system copies the original position data and applies it, significantly reducing the number of switch operations needed
2Ease of operation
If the display unit shows main display picture in first mode, then important information is visible, but switching to second mode requires multiple operations
Solution Approach 1:
The system pre-stores the display position information from the first display mode before switching to the second mode. When the rider returns to the first mode, the system automatically restores the cursor position to where it was before switching, eliminating the complexity of manual navigation and making mode switching easier

AI summary
A display system (2) which is to be installed in a straddled vehicle (1), includes: a display unit (20); and a communication unit (22) which is communicably connected to a portable terminal (30). The display system (2) is configured to: switch a display mode of the display unit (20) from a first display mode to a second display mode in response to an operation performed by a rider on a handle switch (3) of the vehicle (1); display a main display picture (100) on the display unit (20) in the first display mode; and display at least a launcher display picture (140) on the display unit (20) in the second display mode. In the launcher display picture (140), at least some of a plurality of icons (42a to 42e) are displayed side by side in a certain direction (D2). In the launcher display picture (140), a first icon that is currently selected by the rider, a second icon that was selected by the rider last time, a third icon to be selected by the rider next time, and a back button (43) located adjacent to the first icon are displayed in the certain direction (D2).
