Vehicle Display Layout With Hidden Haptic Control Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display and operating devices in motor vehicles lack a precise and intuitive method for operating functions, particularly when requiring haptic feedback and minimal gaze diversion during use.
Innovation Solution
A display and operating device configuration where a mechanical operating element is partially concealed by the display, with a visible, manually operable section, and information related to the operable function is displayed on the display, effectively combining haptic operability with visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical operating element is fully visible and exposed, then it provides good haptic feedback and ease of operation, but it occupies excessive space and complicates the device structure
Solution Approach 1:
The operating element is nested behind the display, with only a portion protruding laterally. The display serves as a cover that conceals the mechanical structure while allowing partial access for operation. This nesting arrangement reduces the overall device footprint and simplifies the structural layout by integrating the operating element within the display assembly rather than placing it externally.
2Device complexity
If the operating element is partially concealed by the display, then the device structure is simplified and space is reduced, but the user cannot see the full operating element
Solution Approach 1:
The display presents visual information corresponding to the operating element's position and state. When the operating element is rotated or adjusted, the display shows graphical representations and status information that replicate the functional state, compensating for the partial concealment and providing the user with complete information about the operating element's current configuration.
3Device complexity
If a touchscreen is used for all operations, then the device structure is simplified, but haptic feedback is lost and precision is reduced
Solution Approach 1:
The solution merges touchscreen technology with a mechanical operating element. The display surface functions as a touchscreen for certain operations, while the protruding mechanical element provides haptic feedback and precise control for specific functions. This combination allows the system to leverage both digital and mechanical advantages, achieving both structural simplicity and operational precision.
4Ease of operation
If the operating element protrudes significantly, then it is easily operable, but it increases the device's external dimensions
Solution Approach 1:
Instead of having the entire operating element protrude, only a sufficient portion protrudes laterally to enable effective manual operation. This partial protrusion provides the necessary haptic feedback and operational leverage while minimizing the increase in device external dimensions. The display covers the remaining portion, maintaining a compact overall form factor.
