Dynamic Vehicle Handle Input Device with Multi-Function Buttons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle input devices with fixed buttons are inefficient, distracting, and hinder driving stability due to the need to search for specific buttons, especially when multiple functions are required during operation.
Innovation Solution
An input device integrated into a vehicle handle with dynamically changeable buttons, allowing functions to be altered based on user input, vehicle state, and environmental conditions, utilizing a touchscreen and directional keys for intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple fixed buttons are disposed in the handle for different functions, then the vehicle can perform various operations, but the driver must search for the right button which diverts attention from driving
Solution Approach 1:
A single button structure is designed to perform multiple functions through different input modes (rotation directions, pressing actions, long/short pressing). The button can execute first functions through rotation, second functions through pressing, and third functions through combination inputs, eliminating the need for multiple separate buttons while maintaining functional versatility.
Solution Approach 2:
The button's function is made dynamic rather than static. The same button structure can switch between different functions based on the input mode (rotation direction, pressing duration, combination inputs). This dynamic functionality allows the system to adapt to different operational needs without requiring the driver to locate different physical buttons.
2Adaptability or versatility
If many buttons are disposed in the handle to provide various functions, then the vehicle operation capabilities are enhanced, but the driver's attention is diverted from the road due to button searching
Solution Approach 1:
One multi-functional button replaces many single-function buttons, reducing the physical space required in the handle and minimizing the driver's search time. The button can execute multiple functions through different input modes including rotation in different directions, varying pressing durations, and combination inputs, thereby maintaining comprehensive functional capability while improving driving safety.
3Ease of manufacture
If fixed-function buttons are used in the handle, then each button has a dedicated purpose, but frequently used and infrequently used buttons are not efficiently differentiated
Solution Approach 1:
The button system dynamically adapts to operational frequency and context. Common functions can be accessed through simple rotation or pressing actions, while less frequent functions are available through combination inputs or extended pressing. The system can also dynamically change functions based on vehicle state (e.g., ignition on/off, driving mode), allowing frequently used functions to be prioritized without requiring separate physical buttons for each function.
