Integrated Shift Steering Control Apparatus for In-Wheel Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-wheel system vehicles have a high number of components and increased costs due to separate shift and steering control mechanisms, which can lead to control errors and accidents.
Innovation Solution
An integrated control apparatus with a dial for steering control and a shift button integrated into one component, using a printed circuit board to detect dial rotation and button signals, and a slider to manage button exposure, reducing component count and preventing control errors by distinctiating shift and steering control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate shift control mechanism and steering control mechanism are configured, then control functions are independent and reliable, but number of components and costs increase
Solution Approach 1:
The patent combines the shift control mechanism and steering control mechanism into a single integrated control apparatus. The shift button and dial are integrated into one component structure, allowing both shift control and steering control to be performed through a single unified device, thereby reducing the number of components while maintaining control reliability through distinct operational modes for each function.
2Ease of manufacture
If separate shift control mechanism and steering control mechanism are configured, then each mechanism can be optimized independently, but costs and device complexity increase
Solution Approach 1:
The patent merges the shift control mechanism and steering control mechanism into a single integrated control apparatus. The shift button and dial are integrated into one component structure, allowing both shift control and steering control to be performed through a single unified device, thereby reducing the number of components while maintaining control reliability through distinct operational modes for each function.
3Device complexity
If shift control and steering control use the same operation manner, then control mechanism is simple, but risk of control error increases
Solution Approach 1:
The patent applies local quality by giving different operational characteristics to different parts of the integrated control apparatus. The shift button provides discrete, momentary press operations for shift control, while the dial provides rotational, continuous control for steering. This differentiation in local operational qualities reduces control errors while maintaining a unified control structure.
4Device complexity
If integrated control apparatus is used, then number of components and costs are reduced, but functionality and versatility may be compromised
Solution Approach 1:
The patent achieves universality by designing the integrated control apparatus to perform multiple functions through a single unified structure. The dial serves dual purposes: rotational operation for steering control and press operation for shift control. The actuator system is also multi-functional, responding to both rotational inputs and press inputs to execute different control commands, thereby maintaining full control functionality while reducing component count.

AI summary
An integrated control apparatus for in-wheel system vehicle is provided. The apparatus includes a shift button for a shift control and a dial for a steering control which are assembled integrally to each other to form one integrated component. The apparatus provides a driver with vehicle information through an operation of the dial when the steering control is not performed, and eliminates a risk of accidents occurring due to a control error by configuring a shift control manner and a steering control manner to be different from each other.
