Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety features are implemented for human operators, then operator safety is improved, but AI-operated vehicle functionality is restricted
Solution Approach 1:
A solid-state relay system acts as an intermediary between the safety lever switch and the hydraulic control system. The relay receives signals from the safety lever and conditionally routes them to bypass the safety feature when AI operation is detected, allowing the system to maintain safety functionality for human operators while enabling unrestricted operation for AI-controlled vehicles.
Solution Approach 2:
The patent replaces traditional mechanical relay systems with solid-state relay devices. This substitution eliminates mechanical moving parts, improving reliability and reducing maintenance requirements. The solid-state relays use electronic switching components to achieve the same signal routing function, enabling more precise control over the bypass condition for AI operation.
2Ease of manufacture
If mechanical relay systems are used to bypass safety features, then installation is simplified, but reliability decreases due to moving parts
Solution Approach 1:
The patent explicitly replaces mechanical relay systems with solid-state relay devices. The solid-state relays use electronic switching components (such as transistors or solid-state switches) instead of mechanical moving parts. This substitution maintains the ease of installation while dramatically improving reliability by eliminating wear, friction, and mechanical failure modes associated with traditional relay systems.
3Ease of manufacture
If traditional relay systems are used, then installation is easier, but electromagnetic protection is insufficient
Solution Approach 1:
The solid-state relay system provides superior electromagnetic protection compared to traditional mechanical relays. The solid-state components are inherently more resistant to electromagnetic interference and signal spikes. The system includes electromagnetic protection circuits that shield the engine control unit from noise and interference, ensuring reliable operation in the harsh electromagnetic environment of construction equipment.
4Reliability
If solid-state relay system is implemented, then reliability and electromagnetic protection are improved, but system complexity increases
Solution Approach 1:
The solid-state relay system is designed to perform multiple functions within a single integrated circuit board. The relay system handles signal routing, electromagnetic protection, and AI operation detection simultaneously. By consolidating these functions into one multi-functional device, the patent reduces overall system complexity despite the advanced capabilities provided by solid-state technology.
