Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a built-in battery is equipped in the electric bicycle, then the electric bicycle can supply electric power for driving the motor, but it adds battery cost and vehicle loading
Solution Approach 1:
The patent extracts the battery from the electric bicycle vehicle body, transforming it from a built-in component to an externally carried power source. The battery is now held by the user rather than being fixed in the vehicle, which eliminates the weight burden from the vehicle structure while maintaining the electric power supply function for the motor.
Solution Approach 2:
The patent introduces a power supply interface and control system as intermediaries between the user-carried battery and the motor. The battery connects to the motor through a standardized interface that includes power transmission and authentication components, enabling flexible power supply without direct battery installation in the vehicle.
2Use of energy by moving object
If a built-in battery is equipped in the electric bicycle, then the electric bicycle can supply electric power for driving the motor, but it increases battery cost
Solution Approach 1:
The patent creates a universal battery interface that can serve multiple functions: power supply for the motor, authentication for vehicle access, and potential sharing economy applications. This multi-functional interface reduces the need for dedicated expensive battery systems by making the power supply component versatile and shareable across different users and vehicles.
Solution Approach 2:
The user carries and manages their own battery, performing self-service for power supply rather than relying on the vehicle owner's built-in battery. This shifts the battery investment to the user level, enabling battery sharing and reducing overall system costs through resource optimization.
3Duration of action of moving object
If the battery is fully charged for 70 kilometers riding range, then the electric bicycle can provide sufficient power, but more than 85% of users ride for shorter than 15 kilometers causing long idling and energy wastage
Solution Approach 1:
The patent transforms the static battery system into a dynamic one where the battery can be easily removed, carried, and replaced by the user. This dynamic configuration allows users to adapt the power supply to their actual needs - carrying the battery only when needed and removing it during idling periods, thereby eliminating energy wastage from stationary charged batteries.
Solution Approach 2:
The user charges and prepares the battery in advance before needing to use the electric bicycle. The battery authentication system performs preliminary verification when the user approaches the vehicle, enabling quick connection and immediate use without unnecessary idling of charged batteries in the vehicle.
4Ease of operation
If remote pairing activation is implemented, then the electric bicycle can be unlocked and activated remotely, but it requires authentication systems and control mechanisms
Solution Approach 1:
The patent merges the battery authentication function with the vehicle access control system. The same interface that connects the battery for power supply also performs authentication for vehicle unlocking and activation. This combination eliminates the need for separate authentication mechanisms, reducing overall system complexity while maintaining remote activation capability.
