Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electric telehandlers are used in emission-restricted zones, then environmental compliance is improved, but battery autonomy becomes insufficient for long-distance travel
Solution Approach 1:
The telehandler is designed with a universal power system that can operate in multiple modes: electric mode for emission-restricted zones and hybrid mode for long-distance travel. The vehicle can switch between battery-only operation and generator-assisted operation, making it suitable for both environmental compliance and extended autonomy requirements.
Solution Approach 2:
The power supply system is made dynamic through the ability to switch between different configurations. The telehandler can transition from a purely electric configuration to a hybrid configuration with a diesel generator, allowing the operator to adapt the power system to the specific operational requirements of each task or location.
2Object-affected harmful factors
If battery recharging procedures are implemented, then environmental compliance is maintained, but operational time is lost
Solution Approach 1:
The telehandler is equipped with a diesel generator that can be activated in advance to recharge the battery before it is fully depleted. This preliminary action ensures that the vehicle maintains operational continuity and avoids interruptions for external recharging, as the generator can top up the battery during operational pauses or low-demand periods.
Solution Approach 2:
The hybrid power system enables continuous operational capability by allowing the diesel generator to recharge the battery while the vehicle is still in use. This eliminates downtime associated with external recharging, as the battery can be recharged during operational cycles, maintaining continuous useful action without interruption.
3Object-affected harmful factors
If multiple electric telehandlers are purchased for different zones, then environmental compliance is ensured, but acquisition cost increases
Solution Approach 1:
The telehandler is designed as a universal vehicle that can operate in both emission-restricted zones and areas without restrictions. By incorporating a switchable hybrid power system, a single vehicle replaces the need for multiple specialized vehicles, reducing the total number of units required in the fleet.
Solution Approach 2:
The dynamic power configuration allows one telehandler to adapt to different operational environments. The vehicle can switch between electric-only mode for restricted zones and hybrid mode for unrestricted areas, eliminating the need to maintain separate fleets for different zones and reducing overall acquisition costs.
