Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electric telehandlers are used in restricted environments, then environmental compliance is improved, but battery autonomy becomes insufficient for long-distance movement
Solution Approach 1:
The telehandler is designed with a universal power supply system that can accept both battery power (for emission-restricted zones) and diesel fuel (for long-distance travel). The vehicle can switch between electric motor and diesel engine propulsion modes, making it suitable for both environmentally sensitive areas and situations requiring extended range.
Solution Approach 2:
The power supply configuration is made dynamic and adjustable. Users can switch between fully electric mode and diesel-assisted mode based on operational requirements. The system allows real-time adaptation between different power sources to optimize for either emission compliance or travel autonomy depending on the work context.
2Object-affected harmful factors
If dedicated electric telehandlers are purchased for restricted areas, then environmental compliance is improved, but user costs increase due to additional equipment
Solution Approach 1:
Instead of requiring separate electric and diesel telehandlers for different zones, this invention provides a single vehicle that performs both functions. The dual-power capability eliminates the need for companies to maintain multiple specialized vehicles, reducing capital expenditure and operational complexity.
Solution Approach 2:
The invention merges two previously separate solutions (electric telehandler for restricted zones and diesel telehandler for general use) into a single integrated vehicle. By combining both powertrain systems in one machine, it eliminates the need for multiple vehicles while maintaining compliance with environmental regulations.
3Duration of action of moving object
If battery capacity is increased to extend autonomy, then operational duration is improved, but vehicle weight and cost increase
Solution Approach 1:
The system provides dynamic power supply options where the diesel engine can supplement battery power during high-demand periods or extend operational duration without requiring excessively large battery packs. This allows the vehicle to maintain reasonable weight while achieving extended autonomy through intelligent power management.
Solution Approach 2:
The diesel fuel tank provides pre-stored energy that can be converted to electrical power when needed. This preliminary energy storage in chemical form (fuel) allows the system to extend operational duration without carrying proportionally large battery capacities, thereby avoiding excessive weight increase.
