Modular Vehicle Control Dial for Detachable One-Hand Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary actuators in vehicles are difficult to operate conveniently from non-standard positions, such as those deviating from the usual driver's seat, due to their fixed location in the center console, making it hard for passengers and potentially future autonomous drivers to access and control vehicle functions.
Innovation Solution
A modular rotary actuator design featuring a separate operating module with sensors for detecting rotational movement, allowing independent operation and control of vehicle devices, including audio systems and lighting, using a handle that can be used one-handedly from various positions, with optional touch-sensitive display and haptic feedback for intuitive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotary actuator is fixed in the center console, then it can be operated by the driver and front passenger, but it becomes difficult to access for passengers seated at a distance or for autonomous drivers
Solution Approach 1:
The rotary actuator is divided into two independent modules: a base module that remains fixed in the center console and an operating module that can be detached and moved. This segmentation allows the operating module to be repositioned according to different user needs while the base module stays in its original location.
Solution Approach 2:
The operating module transitions from a fixed state (when attached to the base module) to a mobile state (when detached), enabling dynamic adaptation to different seating positions and user requirements throughout the vehicle.
2Adaptability or versatility
If the operating module is made independent with energy storage, then it can be operated from any position, but the device complexity increases
Solution Approach 1:
The operating module is designed as a universal control unit that can function independently with its own energy storage or be attached to the base module for additional functionality. This multi-functional design allows it to serve different purposes depending on its operational state.
Solution Approach 2:
The operating module is equipped with its own electrical energy storage device, allowing it to operate autonomously without requiring connection to the vehicle's electrical system or the base module, thereby enabling independent operation from any position in the vehicle.
3Ease of operation
If the operating module is detached from the base module, then it can be used as a portable remote control, but the housing must be held securely to enable rotary movement
Solution Approach 1:
The operating module features a rounded, ergonomic housing design that is easy to grasp and hold securely in one hand, facilitating comfortable rotary operations without requiring two hands or complex handling techniques.
