Solution Overview
Problem
Existing vehicles for maintaining green spaces, such as lawns and meadows, have complex steering systems with many mechanical components that are prone to wear and tear, requiring time-consuming and costly maintenance.
Innovation Solution
A simplified steering method using wired or wireless transmission means directly connects a steering sensor to an electronic processing unit, which controls the vehicle wheels, eliminating complex intermediate circuits and reducing mechanical components, allowing for maintenance-free and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a steering linkage consisting of several steering rods and joints is used to transmit steering movements mechanically, then the steering function is achieved, but the device complexity increases and reliability decreases due to wear and tear of multiple components
Solution Approach 1:
The patent replaces the mechanical steering linkage system (steering rods, joints, and their physical connections) with an electronic control system. Steering sensors detect the steering wheel position and transmit electrical signals through wiring to electronic control units, which then control hydraulic or electric actuators to position the wheels. This substitution eliminates the complex mechanical transmission components that are prone to wear and failure, thereby improving reliability while reducing device complexity.
Solution Approach 2:
The patent introduces electronic intermediaries (steering sensors, electronic control units, and wiring) between the steering wheel and the wheel positioning mechanism. These intermediaries replace the direct mechanical linkage, allowing for more reliable signal transmission and control while reducing the number of mechanical components that can fail.
2Ease of operation
If a mechanical steering linkage with multiple components is used, then steering control is achieved, but maintenance time and costs increase
Solution Approach 1:
By replacing the mechanical steering linkage with an electronic control system, the patent eliminates components that require regular mechanical maintenance such as lubrication, adjustment, and replacement of worn parts. The electronic sensors, wiring, and control units have significantly lower maintenance requirements, reducing both maintenance time and costs while maintaining effective steering control.
3Device complexity
If wired or wireless steering transmission means are used to connect steering sensor to electronic processing unit, then device complexity is reduced, but new components are introduced that require different types of maintenance
Solution Approach 1:
The patent simplifies the overall device structure by replacing complex mechanical linkages with electronic transmission means. While this introduces electronic components, the net effect is reduced complexity because electronic components have fewer moving parts and simpler assembly requirements. The wiring harness or wireless communication systems are more compact and require less precise mechanical alignment than traditional steering linkages.
