Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a diesel engine is used to power material processing apparatus, then sufficient mechanical power can be provided to processing units and mobility systems, but environmental emissions increase and environmental concerns worsen
Solution Approach 1:
The power system is segmented into multiple independent power sources (electrical system with battery and generator, hydraulic system with pump and motor, and diesel engine) that can operate independently or in combination. This allows the apparatus to provide sufficient mechanical power through coordinated operation of multiple systems while reducing reliance on the diesel engine, thereby lowering emissions.
2Object-generated harmful factors
If the diesel engine is replaced with electrical motors or a conventional diesel-electric hybrid system, then emissions can be reduced, but the cost becomes prohibitive
Solution Approach 1:
Instead of completely replacing the diesel engine with an expensive all-electric or hybrid system, the invention applies partial electrical power through a battery-powered electrical system that supplements the existing diesel engine. This partial electrification reduces emissions without incurring the prohibitive costs of a complete system replacement, making the solution economically viable.
3Power
If hydraulic systems are used to power components, then mechanical power can be delivered efficiently, but the risk of oil spillage increases
Solution Approach 1:
The power delivery system is segmented into multiple independent systems (electrical system with electric motors, hydraulic system with hydraulic motors, and direct mechanical coupling options). This segmentation allows critical components to be powered by non-hydraulic means, reducing the overall hydraulic system size and potential oil spillage risk while maintaining efficient mechanical power delivery through alternative pathways.
4Object-generated harmful factors
If a hybrid power system with multiple power sources is implemented, then emissions and oil spillage can be reduced, but the system complexity increases
Solution Approach 1:
The diesel engine is designed with multi-functionality to serve multiple roles: it can directly drive processing units through mechanical coupling, power the electrical system through the generator, or provide hydraulic power through the pump. This universal design allows a single engine to fulfill multiple power delivery functions, reducing the need for separate dedicated systems and thereby limiting the increase in overall system complexity despite the hybrid architecture.
