Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a high-capacity battery is built in for one-piece AR glasses, then the duration is improved, but the size and weight increase, making it bulky and uncomfortable for long-term wear
Solution Approach 1:
The system is divided into two operational modes: standalone mode with integrated battery for portability, and tethered mode for extended duration. This segmentation allows the product to offer both lightweight design and long duration without compromising either.
Solution Approach 2:
The AR glasses are designed with multi-functionality to operate in two distinct modes: standalone operation with integrated battery and tethered operation connected to host device. This universality enables the product to serve different user needs without requiring separate designs.
2Weight of moving object
If the AR glasses are designed as tethered products without battery, then the weight and size are reduced, but the portability and user experience are degraded due to wired connection requirement
Solution Approach 1:
The system dynamically adapts between two operational states: tethered mode for lightweight design and standalone mode for portability. The glasses can switch between these states based on user needs, making the design both lightweight and versatile.
Solution Approach 2:
The AR glasses are designed with multi-functionality to operate in two distinct modes: standalone operation with integrated battery and tethered operation connected to host device. This universality enables the product to serve different user needs without requiring separate designs.
3Reliability
If a complete computing processing unit is included in one-piece AR glasses, then the functional requirements are met, but the device complexity and size increase
Solution Approach 1:
The computing functionality is segmented between the glasses (basic processing) and host device (advanced processing). This segmentation allows the glasses to meet functional requirements while maintaining simplicity by offloading complex computing tasks to the host.

AI summary
The AR glasses include a power supply unit, a computing processing unit, a communication unit and a wired connector. The wired connector is connected to a host: when the host is not connected, the power supply unit supplies power to the AR glasses, the computing processing unit may receive and process AR glasses data, and the communication unit is configured to perform data communication with an external device; when the host is connected, a host power supply supplies power to the AR glasses and charges the power supply unit, and the computing processing unit is configured to receive AR glasses data, send the data to a processor of the host through the wired connector for processing, and receive the processed AR glasses data through the wired connector.
