Integrated Handle Control Device for Vehicle Interior Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems require separate components for steering, acceleration, braking, and shifting, which occupy interior space, increase weight and cost, and hinder passenger mobility and storage options, especially with the trend towards autonomous driving reducing the driver's control area.
Innovation Solution
A handle-type integrated control device that combines steering, acceleration, deceleration, and shifting controls using a single handle, featuring a speed value receiver, speed controller, steering unit, steering controller, return spring, and damper, allowing for integrated control of vehicle functions through a single handle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components (steering wheel, accelerator pedal, brake pedal, shift lever) are used for vehicle control, then each control function can be performed independently and reliably, but the interior space of the vehicle is reduced and the weight and cost increase
Solution Approach 1:
The patent combines steering, acceleration, deceleration, and shifting control functions into a single integrated handle assembly. The handle includes a steering lever for directional control and a handle housing that rotates for speed control, merging multiple separate control components into one unified device that reduces overall system weight while maintaining independent control reliability through dedicated control units for each function.
Solution Approach 2:
The handle assembly serves multiple control functions simultaneously - it can steer the vehicle through lateral movement of the steering lever, control acceleration and deceleration through rotation of the handle housing, and perform shifting operations. This multi-functional design eliminates the need for separate dedicated components for each control function, reducing total vehicle weight.
2Reliability
If separate components (steering wheel, accelerator pedal, brake pedal, shift lever) are used for vehicle control, then each control function can be performed independently and reliably, but the interior space of the vehicle is reduced
Solution Approach 1:
The patent integrates steering, acceleration, deceleration, and shifting controls into a single handle assembly that occupies minimal interior space. By combining functions that previously required separate components (steering wheel, accelerator pedal, brake pedal, shift lever) into one unified device, the patent maximizes available interior space while maintaining reliable independent control for each function through dedicated control units.
Solution Approach 2:
The handle assembly provides universal control capability for multiple vehicle functions - steering through lateral lever movement, speed control through handle housing rotation, and shifting operations. This multi-functional integration eliminates the need for multiple separate control components scattered throughout the interior, thereby maximizing usable interior space.
3Adaptability or versatility
If multiple control components are mounted in the vehicle, then comprehensive vehicle control functions are available, but the cost of the vehicle increases
Solution Approach 1:
The patent consolidates multiple control functions into a single integrated handle assembly with shared structural components and housing. By merging steering, acceleration, deceleration, and shifting controls into one device with common mechanical elements and integrated control units, the patent reduces the total number of parts that need to be manufactured, assembled, and installed, thereby reducing overall manufacturing cost while maintaining comprehensive control versatility.
Solution Approach 2:
The handle assembly provides versatile control capability for multiple vehicle functions through a single multi-functional device. This universal design eliminates the need to manufacture and install separate dedicated components for each control function, reducing total manufacturing cost while maintaining full control versatility through integrated control units that handle different functions within the same assembly.
4Ease of operation
If a shift lever is exposed through the console, then shifting control is accessible, but passenger mobility is restricted and storage space cannot be increased
Solution Approach 1:
The patent integrates the shifting control function into the handle assembly, combining it with steering and speed control functions. The shift lever is integrated into the handle structure rather than being exposed separately through the console, allowing shifting control to remain accessible while eliminating the need for a separate exposed shift lever that would obstruct passenger movement and prevent storage space expansion in the console area.

AI summary
A handle-type integrated control device includes: a steering lever disposed to be movable in a width direction of a vehicle by a driver's operation; a handle housing disposed at an upper end of the steering lever and configured to rotate, in a front-to-rear direction of the vehicle, about one end of the steering lever by the driver's operation; a speed value receiver disposed at one end of the handle housing to receive an acceleration or deceleration change value; and a speed controller connected to the speed value receiver to receive the acceleration or deceleration change value from the speed value receiver.
