Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional internal combustion engines are used to drive hydraulic pumps and distributors for stabilisers, then the telehandler can achieve sufficient power and stability, but energy consumption increases and environmental sustainability deteriorates
Solution Approach 1:
The patent replaces the traditional hydraulic actuation system with an electric actuation system for the stabilisers. Electric motors directly drive the stabiliser arms through electric actuators, eliminating the need for hydraulic pumps, distributors, and fluid transmission. This substitution of mechanical/hydraulic systems with electric systems reduces energy consumption and improves environmental sustainability while maintaining the stabilisation function.
Solution Approach 2:
The invention extracts and removes the hydraulic components (pumps, distributors, hydraulic fluid systems) from the stabiliser actuation mechanism. By taking out the hydraulic subsystem and replacing it with direct electric actuation, the system achieves lower energy consumption and reduced environmental impact while preserving the essential stabilisation capability.
2Object-affected harmful factors
If hydraulic systems are used for stabiliser actuation, then sufficient force and control are achieved, but noise and pollution levels increase
Solution Approach 1:
The patent substitutes hydraulic power transmission with electric power transmission for stabiliser actuation. Electric motors provide direct mechanical force through electric actuators, eliminating noise-generating hydraulic components and polluting hydraulic fluids. This substitution maintains sufficient actuation force while dramatically reducing noise and pollution harmful factors.
3Loss of energy
If electric actuators are used to replace hydraulic components in stabilisers, then energy efficiency and environmental sustainability improve, but the complexity of the actuation system increases
Solution Approach 1:
The invention extracts and eliminates complex hydraulic components (pumps, distributors, valves, fluid reservoirs, hoses) from the stabiliser actuation system. By removing these interconnected hydraulic elements and replacing them with simpler electric actuators and control electronics, the system actually reduces overall complexity while improving energy efficiency.
Solution Approach 2:
The substitution of hydraulic mechanics with electric actuation simplifies the system architecture. Electric motors and actuators integrate control and power delivery in compact units, whereas hydraulic systems require multiple separate components and fluid management infrastructure. This substitution reduces energy losses and simplifies the actuation system.
4Productivity
If hybrid electro-hydraulic systems are implemented, then some improvement in efficiency is achieved, but the limitations of traditional telehandlers are only partially addressed
Solution Approach 1:
The patent extracts the hydraulic subsystem from the electro-hydraulic hybrid system, removing pumps, distributors, and hydraulic fluid infrastructure. This extraction creates a fully electric system that achieves higher operational efficiency by eliminating energy losses in hydraulic transmission, while also reducing overall system complexity compared to maintaining hybrid electro-hydraulic architecture.
Solution Approach 2:
The complete substitution of hydraulic components with electric actuators achieves full electro-actuation of stabilisers. This eliminates the inefficiencies and complexities of hybrid systems, delivering superior operational efficiency through direct electric drive while simplifying the actuation architecture.
