Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image capturing devices are equipped in the mobile unit to provide different functionalities (color camera, monochrome camera), then the functionality versatility is improved, but the overall size and manufacturing cost increase
Solution Approach 1:
The patent applies universality by designing a single image capturing device that can perform multiple functionalities (color imaging and monochrome imaging) through dynamic filter configuration. The filter is divided into multiple portions with different optical properties, allowing the same hardware to adapt to different functional requirements without needing separate dedicated devices for each function.
Solution Approach 2:
The filter is segmented into multiple portions (e.g., first portion for color imaging, second portion for monochrome imaging), each optimized for specific functional requirements. This segmentation allows the system to switch between different functionalities by selecting which filter portion to use, thereby achieving versatility without requiring multiple complete image capturing devices.
2Device complexity
If a single image capturing device is used to perform multiple functionalities, then the size and cost are reduced, but the device cannot be dynamically tuned for different modes of operation
Solution Approach 1:
The patent implements dynamics by making the filter configuration changeable during operation. The system can dynamically switch between different filter portions based on the required mode of operation (color or monochrome), enabling a single device to adapt to different functional requirements in real-time without being fixed to a single configuration.
Solution Approach 2:
The patent changes the optical parameters of the image capturing device by switching between different filter portions with different properties. By altering which filter portion is active, the system modifies the device's operational characteristics to match the required functionality, achieving dynamic tuning capability within a single device structure.
