Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple short range wireless communication modules are used to improve interaction capabilities, then the ability to determine terminal location and orientation is improved, but the device complexity increases
Solution Approach 1:
The display apparatus is divided into multiple communication modules positioned at different locations, with each module independently identifying terminal positions. This segmentation allows precise location determination through modular detection while maintaining manageable system complexity through standardized module design.
Solution Approach 2:
Each communication module is designed to perform multiple functions: wireless communication, location detection, and orientation determination. This multi-functionality reduces the need for separate dedicated components, thereby improving measurement capabilities without proportionally increasing overall device complexity.
2Measurement precision
If geomagnetic sensors are integrated into both display apparatus and mobile terminal for orientation detection, then the relative direction determination accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent combines geomagnetic sensors in both the display apparatus and mobile terminal to create a collaborative orientation detection system. By merging detection capabilities from both devices and comparing their respective geomagnetic data, the system achieves accurate relative direction determination while distributing the sensing burden across multiple components.
Solution Approach 2:
The system uses feedback from geomagnetic sensor readings in both devices to continuously adjust and refine orientation determination. The mobile terminal and display apparatus exchange orientation data, allowing each device to compensate for its own sensing errors by referencing the other's measurements, thereby improving overall precision.
