Vehicle Display State Highlighting for Low-Distraction Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face challenges in providing clear visual cues for switching between different operating states without causing driver distraction, particularly when transitioning between head-up displays and instrument clusters.
Innovation Solution
A display system with a switching mechanism and actuating means that allows for visually perceptible changes in display indications, such as illumination or glow effects, to highlight the active operating state, minimizing distraction by using intuitive controls like rocker switches or touch-sensitive elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual indications are displayed large and conspicuously to improve perceptibility, then the driver is distracted from the driving situation
Solution Approach 1:
The patent applies local quality by displaying visual indications at specific local positions within the existing display content rather than as separate prominent elements. The indications are integrated into the display at locations that do not dominate the visual field, providing subtle cues that are perceptible to the driver without creating excessive distraction. This resolves the contradiction by making the indication quality local and context-appropriate rather than globally prominent.
Solution Approach 2:
The patent uses partial action by implementing visual indications that are just sufficient to convey the operating state information without being excessive. The indications are designed to provide the minimum necessary visual change to communicate the active display device, avoiding over-emphasis that would cause distraction. This partial approach balances perceptibility needs with distraction reduction.
2Object-affected harmful factors
If visual indications are displayed small and inconspicuously to reduce driver distraction, then the operating state becomes difficult to recognize
Solution Approach 1:
The patent positions visual indications at carefully selected local locations within the display where they can be effectively perceived without being prominently intrusive. By integrating indications into the existing display layout at appropriate positions, the system achieves adequate recognizability while maintaining a low-profile appearance that minimizes distraction.
Solution Approach 2:
The patent implements visual indications with just enough visual weight to be recognizable - not so strong as to cause distraction, but sufficient to convey the operating state. This partial action approach finds the optimal middle ground between visibility and subtlety, ensuring the information is communicated effectively without excessive emphasis.
3Loss of information
If additional displays are added to highlight operating state to improve perceptibility, then occlusion and contrast limitations in head-up display are worsened
Solution Approach 1:
The patent merges the operating state indication function with the existing display content by integrating visual indications directly into the display output. Rather than adding separate indication displays that would compound occlusion and contrast issues, the indications are combined with the primary display content, sharing the same visual channel and resources. This resolving approach avoids the harms of additional displays while maintaining perceptibility.
Solution Approach 2:
The patent makes the existing display device multi-functional by using it both for primary information display and for indicating the operating state through integrated visual indications. This universal approach eliminates the need for dedicated indication displays, reducing overall display complexity and avoiding the occlusion and contrast limitations that would result from multiple overlapping displays.
