Vehicle Display Partitioning for Switch-Based Image Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems require drivers to memorize complex gestures to change images, leading to increased costs due to the need for gesture-detecting sensors and complexity in operation.
Innovation Solution
A vehicle display apparatus with a display panel divided into inner and outer regions, using switches positioned near and distant from the steering wheel to allow easy and safe image changes without the need for gesture detection sensors, where the inner image is frequently changed using a switch near the steering wheel and the outer image is changed using a switch further away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gesture detection sensors are used to detect driver gestures for changing images, then the driver can change images without directly touching the display apparatus, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the gesture detection function from the display apparatus by using the vehicle's existing audio recognition system to detect voice commands instead. This removes the need for dedicated gesture sensors while maintaining contactless operation capability, thereby reducing device complexity and cost.
Solution Approach 2:
The patent utilizes the vehicle's existing audio recognition system for multiple purposes - both for voice-based image changing and potentially other vehicle control functions. This multi-functional approach eliminates the need for separate gesture detection hardware, reducing overall system complexity.
2Adaptability or versatility
If multiple gestures are assigned to different image types, then the driver can access various information, but the driver has to memorize various gestures requiring memorizing operations
Solution Approach 1:
The patent implements a sequential display mechanism where different image types are shown in a predetermined order (e.g., first outer image, then second outer image, then inner images). The driver can cycle through images by issuing a single type of voice command repeatedly, eliminating the need to memorize different gestures for different image types.
Solution Approach 2:
The system automatically manages the complexity of image selection by implementing its own sequencing and presentation logic. Instead of requiring the driver to navigate complex gesture combinations, the system self-manages the display sequence based on simple voice commands, reducing the cognitive burden on the driver.
3Ease of operation
If switches are positioned at different distances from the steering wheel, then frequent changes can be made easily with a near switch, but the driver must reach further for less frequent changes
Solution Approach 1:
The patent assigns different functional qualities to switches based on their location: the first switch (closer to steering wheel) is optimized for frequent operations with easy accessibility, while the second switch (further away) is optimized for less frequent operations. This local differentiation allows each switch to be optimally positioned for its specific use case without compromising overall safety.
Solution Approach 2:
The system dynamically adapts to the driver's needs by providing multiple access points at different locations. The driver can choose the appropriate switch based on the urgency and frequency of the operation needed, with closer switches for urgent/frequent changes and farther switches for non-urgent/infrequent changes.

AI summary
Present application discloses display apparatus including: display panel having display surface to display image; and overlaid member overlaid on display surface. Overlaid member partitions display surface into inner region at least partially surrounded by overlaid member, and outer region situated outside overlaid member. Image contains inner and outer images displayed in inner and outer regions. Display panel includes signal generator for generating first image signal for changing content of the inner image displayed in inner region in response to first switching signal outputted from first switch. Signal generator generates second image signal for changing content of the outer image displayed in outer region in response to second switching signal outputted from second switch which is more distant from steering wheel than first switch.
