Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If electric vehicles use battery power alone, then they achieve emission-free driving, but they suffer from charging inconvenience and limited driving range
Solution Approach 1:
The patent introduces a contact network device as an intermediary between the vehicle and the power source. This device includes a telescopic rod with contact shoes that physically connect to overhead contact lines, serving as a mediator to transfer electrical energy from the infrastructure to the vehicle, thereby extending driving range without compromising emission-free operation
Solution Approach 2:
The contact network device employs a telescopic rod that can dynamically extend and retract based on driving conditions. During high-power consumption scenarios or when contact network infrastructure is available, the rod extends to draw power from overhead lines. During low-power scenarios or when infrastructure is absent, it retracts and relies on battery power, creating a dynamic hybrid power system
2Duration of action of moving object
If electric vehicles are equipped with larger batteries to extend range, then driving range increases, but vehicle weight and cost increase
Solution Approach 1:
The contact network device serves as an external power intermediary, allowing the vehicle to draw power from infrastructure rather than carrying all necessary energy onboard. This eliminates the need for oversized batteries, maintaining lighter vehicle weight while achieving extended operational range through the external power connection
Solution Approach 2:
The contact network device provides multiple functions: it serves as both a power source during high-demand periods and as a tracking/navigation reference for the vehicle. This multi-functionality reduces the need for separate heavy battery systems, as the same infrastructure connection provides both energy and guidance
3Power
If contact network device extends telescopic rod to connect with contact network, then power supply capability improves, but device complexity and potential safety risks increase
Solution Approach 1:
The telescopic rod is designed with dynamic extension and retraction capabilities controlled by an extension control unit. The rod only extends when power is needed and when the vehicle is in proximity to contact network infrastructure, reducing the time the complex mechanism is exposed and minimizing potential safety risks while maintaining power supply capability
4Productivity
If intelligent network system is built along roads for power supply and information transmission, then vehicle operation efficiency improves, but infrastructure construction cost increases
Solution Approach 1:
The contact network infrastructure serves dual purposes: it provides electrical power to vehicles through the contact lines while simultaneously serving as a physical reference framework for vehicle tracking and navigation. This multi-functionality allows a single infrastructure system to replace what would otherwise require separate power supply and navigation systems, reducing overall construction costs
Solution Approach 2:
The patent merges the power transmission function and the navigation/reference function into a single integrated contact network system. The same overhead lines that deliver electricity also serve as spatial references for vehicle positioning and route following, combining multiple infrastructure functions into one system to reduce construction complexity and cost
