Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parking piles are deployed for each parking space, then parking management coverage is improved, but deployment cost increases
Solution Approach 1:
Multiple signal transmitting apparatuses are merged into a single parking area to provide collective coverage, replacing the traditional one-to-one mapping between parking piles and parking spaces. This allows a group of apparatuses to serve multiple vehicles simultaneously, reducing overall deployment cost while maintaining management coverage.
Solution Approach 2:
The signal transmitting apparatuses are designed to serve multiple functions: they not only transmit wireless signals for location determination but also collectively define the parking area boundary. This multi-functionality reduces the need for dedicated infrastructure at each parking space.
2Measurement precision
If GPS positioning is used to determine vehicle location, then location determination capability is improved, but accuracy in non-uniform deployments deteriorates
Solution Approach 1:
The patent introduces wireless signal intensity as an intermediary parameter to determine vehicle location. Instead of relying directly on GPS coordinates, the system uses the intensity of wireless signals received from multiple apparatuses as a mediator to infer position, which provides more reliable accuracy in non-uniform deployment scenarios.
Solution Approach 2:
The patent replaces the GPS satellite-based positioning system with a local wireless signal-based system. This substitution uses electromagnetic signal propagation characteristics in the local environment rather than satellite signals, making the system more adaptable to non-uniform ground deployments and providing better accuracy for parking area determination.
3Measurement precision
If signal intensity threshold is set high, then location determination accuracy is improved, but coverage area decreases
Solution Approach 1:
The patent transitions from using a single signal intensity threshold to a multi-dimensional approach by considering signal intensities from multiple apparatuses simultaneously. This dimensional expansion allows the system to maintain high accuracy requirements while covering a larger area, as the combined signal information provides more robust location determination.
Solution Approach 2:
The coverage area is segmented into multiple zones, each associated with different signal transmitting apparatuses. By dividing the overall coverage area into smaller segments and evaluating signal intensities from multiple segments, the system achieves both high accuracy (through selective threshold application) and extensive coverage (through cumulative zone coverage).
