Floated Button Vehicle Screen Assembly for Tactile Driver Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicle display screens require drivers to visually and physically interact with large screens while driving, leading to distraction and increased safety hazards due to the need to locate and touch function buttons, which can result in car accidents.
Innovation Solution
A floated button system is integrated into the vehicle screen assembly, allowing drivers to interact with frequently used buttons without needing to visually focus on the screen by maintaining a consistent position relative to the display, reducing the time required for interaction and minimizing distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drivers interact with traditional large vehicle display screens by visually locating and touching function buttons, then complete human-vehicle interaction operations can be achieved, but driver visual attention is distracted from driving leading to safety hazards
Solution Approach 1:
The patent divides the traditional large display screen into two separate components: a display screen for visual information and a floated button for tactile operation. This segmentation allows the button to be positioned within easy reach of the driver without requiring visual attention, thus maintaining ease of operation while improving driving safety.
Solution Approach 2:
The floated button acts as an intermediary device between the driver and the vehicle's control system. It provides a tactile interface that can be operated without visual attention, mediating the interaction between the driver and vehicle functions while reducing distraction from the main display screen.
2Measurement precision
If drivers focus attention on the vehicle screen assembly to locate and touch buttons, then accurate function selection is achieved, but interaction time increases causing distraction from driving
Solution Approach 1:
By separating the display function from the control function, the patent eliminates the need for visual localization of buttons. The floated button provides tactile feedback and consistent spatial positioning, allowing drivers to operate controls through touch alone, thus achieving accurate function selection without increasing interaction time.
Solution Approach 2:
The floated button is pre-positioned within easy reach of the driver in a fixed location that does not require visual search. This preliminary positioning allows drivers to operate frequently used functions through muscle memory and tactile feedback, achieving accurate control without the time loss associated with visual localization on a large screen.
3Adaptability or versatility
If traditional large display screens are used for all vehicle controls, then comprehensive function display is achieved, but driver distraction and safety hazards increase
Solution Approach 1:
The patent segments the control interface into a display screen for comprehensive function display and a floated button for essential control operations. This allows the display to maintain its versatility in showing various vehicle information and controls, while the separate button provides a distraction-free method for critical operations.
Solution Approach 2:
The floated button provides a localized tactile interface with distinct tactile feedback for specific functions. This local quality allows drivers to operate essential controls through touch alone without needing to visually process the comprehensive display, thus maintaining adaptability while reducing driver distraction.
