Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS signals are used for location determination, then location information can be obtained, but accuracy deteriorates in indoor environments where GPS signals are weak
Solution Approach 1:
The patent combines multiple location determination methods (wireless communications with nearby devices and image recognition) to create a hybrid system that leverages the strengths of each method while compensating for their individual weaknesses, thereby achieving high accuracy location determination indoors without relying solely on unreliable GPS signals
Solution Approach 2:
The patent introduces wireless communications signals and image recognition as intermediary methods between the user interaction device and the physical world, using these intermediaries to determine location when direct GPS signals are unavailable or inaccurate
2Measurement precision
If cell tower triangulation is used for location determination, then location information can be obtained in indoor environments, but accuracy is limited
Solution Approach 1:
The patent merges cell tower triangulation with wireless communications between devices and image recognition techniques, creating a multi-layered location determination system that achieves higher accuracy by combining the coverage of cell towers with the precision of device-to-device communications and visual recognition
Solution Approach 2:
The patent adds new dimensions to location determination by incorporating wireless communications signals and image recognition alongside traditional cell tower triangulation, transitioning from a single-method approach to a multi-dimensional approach that uses multiple types of signals and data sources simultaneously
3Measurement precision
If multiple location methods are combined to improve accuracy, then location precision increases, but system complexity increases
Solution Approach 1:
The patent segments the location determination process into distinct modules: wireless communications module for device-to-device positioning, image recognition module for visual-based location, and integration module for combining results. This segmentation allows each module to operate independently while contributing to the overall location accuracy, managing system complexity through modular design
