Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic sensors are installed above each parking space in indoor parking garages, then the detection accuracy of parking space status is improved, but the construction cost increases
Solution Approach 1:
The patent repurposes existing ceiling-mounted illumination devices to perform both lighting and parking space status detection functions. The illumination device includes a controller that processes ultrasonic signals to detect whether parking spaces are occupied, eliminating the need for separate ultrasonic sensor installations and reducing construction costs while maintaining detection accuracy
Solution Approach 2:
The patent combines the illumination function and detection function into a single integrated device. The ceiling-mounted device includes both light-emitting components for illumination and ultrasonic transmission/reception components for detection, merging multiple functions into one structure to reduce overall system cost and complexity
2Measurement precision
If ultrasonic sensors are installed in outdoor parking lots, then the parking space status can be detected, but the installation difficulty increases due to lack of ceiling structure
Solution Approach 1:
The patent adapts the ceiling-mounted illumination and detection device for use in outdoor parking lots by mounting it on vertical structures such as poles or building facades. The device maintains its dual function of illumination and ultrasonic detection, providing parking space status monitoring in environments without traditional ceiling structures
Solution Approach 2:
The patent transitions the mounting configuration from horizontal ceiling installation to vertical structure mounting. By changing the installation dimension from overhead horizontal surfaces to vertical poles or walls, the device becomes suitable for outdoor parking lots while maintaining its detection and illumination capabilities
3Area of stationary object
If multiple ultrasonic sensors are installed throughout the parking lot, then the coverage of parking space detection is improved, but the device complexity increases
Solution Approach 1:
The patent divides the parking lot into multiple detection zones, each covered by a single multi-functional ceiling-mounted device. Each device independently monitors its assigned parking spaces and communicates status information to a central control system, reducing the total number of devices needed while maintaining comprehensive coverage
Solution Approach 2:
The patent implements a feedback mechanism where each ceiling-mounted device continuously monitors parking space status and communicates this information to a central controller. The central controller processes the data and provides real-time updates to drivers, creating an efficient feedback loop that reduces system complexity while maintaining wide coverage
