Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles that deviate from preset travel routes face challenges in efficiently returning to the route without performing unnecessary operations.
Innovation Solution
A vehicle with a processing device that sets different steering angles for its tires to orient them towards a common central point, allowing efficient return to the travel route by calculating target positions and adjusting steering angles based on current and target tire positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate control units are used for different vehicle functions, then functional versatility is improved, but device complexity and communication overhead increase
Solution Approach 1:
The patent combines multiple control functions (steering, braking, acceleration) into a single control unit that processes all sensor inputs and generates all control outputs. This consolidation eliminates the need for multiple separate control units and their interconnections, reducing device complexity while maintaining full functional versatility through integrated control logic.
Solution Approach 2:
The control unit is designed as a universal controller that can handle multiple vehicle control functions simultaneously. It receives inputs from various sensors (steering angle, brake pressure, accelerator position) and generates multiple control outputs (steering motor control, brake actuator control, acceleration control), making it a multi-functional device that replaces several specialized control units.
2Area of stationary object
If multiple sensors are integrated into a single housing, then space efficiency is improved, but manufacturing precision and assembly difficulty increase
Solution Approach 1:
The patent implements a nested sensor housing structure where multiple sensors are housed within concentric or nested compartments. The first sensor housing contains the first sensor, while the second sensor housing contains the second sensor, with both housings integrated into a compact arrangement. This nesting approach maximizes space efficiency while maintaining manufacturability through modular assembly.
Solution Approach 2:
The sensor system is divided into separate modular housing units (first sensor housing and second sensor housing) that can be manufactured and tested independently before final assembly. This segmentation allows each housing to be optimized for its specific sensor requirements, maintaining manufacturing precision while achieving compact integration through standardized connection interfaces.
3Area of stationary object
If sensor housings are positioned close together, then vehicle space is optimized, but electromagnetic interference between sensors increases
Solution Approach 1:
The patent introduces electromagnetic shielding as an intermediary element between the first sensor and the second sensor. The shielding structure is integrated into the sensor housing design, creating electromagnetic barriers that prevent interference between closely positioned sensors while allowing the housings to remain compact and space-efficient.
Solution Approach 2:
The sensor housings create protected electromagnetic environments for each sensor, isolating them from external electromagnetic interference and from each other. This inert electromagnetic environment allows sensors to operate accurately in close proximity without mutual interference, optimizing vehicle space while maintaining signal integrity.

AI summary
A vehicle: finds a common central point at which a difference between a distance from a current position of a first tire and a distance from a target position of the first tire is within a predetermined range and a difference between a distance from a current position of a second tire and a distance from a target position of the second tire is within a predetermined range; and sets a steering angle of each of a plurality of tires so that the tire will be oriented in a direction of a tangent to a clearance circle whose center is the common central point or oriented in a direction whose angle difference from the direction of the tangent is within a predetermined range.
