Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a virtual reality helmet uses a mobile phone screen instead of an in-built screen, then the device complexity is reduced and ease of manufacture is improved, but the adaptability to different phone models and screen sizes deteriorates, causing image completeness issues
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the imaging area parameters (position and size) based on the detected phone model and screen characteristics. The system stores multiple sets of imaging parameters corresponding to different phone models and automatically selects the appropriate parameters to ensure complete image display across various devices.
Solution Approach 2:
The patent implements dynamics by making the imaging area configurable and adjustable rather than fixed. The system can dynamically modify the imaging area parameters during operation based on the detected phone model, allowing the same helmet to adapt to different devices without physical modifications.
2Adaptability or versatility
If the imaging area is enlarged to accommodate larger phone screens, then the adaptability to different phone sizes is improved, but the manufacturing precision and optical quality deteriorate due to lens limitations
Solution Approach 1:
The patent resolves this contradiction by changing the imaging area parameters (position and size) to match the specific phone model being used. Rather than enlarging the imaging area universally, the system selects from pre-stored parameters optimized for different screen sizes, maintaining optical quality while achieving adaptability.
Solution Approach 2:
The patent applies local quality by optimizing the imaging area parameters specifically for each phone model's screen characteristics. Each phone model has its own set of optimized parameters that ensure the imaging area is precisely matched to that device's screen size and position, rather than using a one-size-fits-all approach.
3Adaptability or versatility
If different imaging parameters are used for different virtual reality helmet models, then the adaptability to various helmet structures is improved, but the device complexity increases due to multiple parameter sets
Solution Approach 1:
The patent applies universality by creating a unified parameter management system that handles multiple helmet models through a single interface. The system stores multiple sets of imaging parameters but provides a universal adaptation mechanism that automatically selects the appropriate parameters based on the detected helmet model, making the system work with various helmets without requiring separate configuration for each.
Solution Approach 2:
The patent implements self-service by enabling the system to automatically detect the helmet model and select the corresponding imaging parameters without user intervention. The system self-configures by matching the detected helmet model with the appropriate pre-stored parameter set, eliminating the need for manual configuration and reducing operational complexity.
