Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex surveying system is used to measure vehicle dimensions precisely, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses reference images of vehicles with known dimensions as copies to determine vehicle properties. Instead of directly measuring the vehicle with complex surveying equipment, the system captures an image of the vehicle and compares it against stored reference images and corresponding dimension data, thereby obtaining accurate vehicle dimensions without requiring complex measurement hardware
Solution Approach 2:
The patent introduces an intermediary approach by using image processing and database comparison as a mediator between the captured vehicle image and the desired dimension data. The system uses reference images and a database of vehicle properties as intermediaries to translate visual information into accurate dimensional measurements, avoiding the need for direct complex surveying
2Productivity
If a complex surveying system is used to determine optimal parking position, then parking space utilization is improved, but device complexity and cost increase
Solution Approach 1:
The system uses reference images and pre-stored vehicle dimension data as copies to determine optimal parking positions. By comparing the captured vehicle image against reference images and retrieving corresponding dimension information from the database, the system efficiently determines suitable parking spaces without requiring complex real-time surveying operations
Solution Approach 2:
The patent performs preliminary action by pre-storing reference images and vehicle dimension data in a database before the actual parking operation. This allows the system to quickly determine vehicle properties and optimal parking positions during operation by simply comparing the captured image against the pre-prepared reference data, significantly reducing the complexity of real-time processing
3Device complexity
If simple photograph is used to determine vehicle type, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The system uses reference images of vehicles with known properties as copies to maintain high measurement precision. By capturing a photograph of the vehicle and comparing it against the reference images in the database, the system can accurately determine vehicle type and properties using a simple camera rather than complex measurement equipment
Solution Approach 2:
The patent uses the database of reference images and vehicle properties as an intermediary that bridges the simple photograph capture and accurate vehicle property determination. The reference data serves as a mediator that translates simple visual information into precise vehicle characteristic identification, maintaining accuracy while using minimal hardware
