Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual camera device is used to photograph different portions, then the capability to capture images is improved, but magnetic field interference between camera devices increases
Solution Approach 1:
A non-magnetic spacer component is introduced between the first and second camera devices to physically separate them and minimize magnetic field interference while maintaining their functional capabilities
Solution Approach 2:
The magnetic interference problem is addressed by extracting and isolating the magnetic components within each camera device using shielding structures, separating the harmful magnetic fields from the operational space
2Adaptability or versatility
If a triple camera device configuration is added to capture more images, then the image capture versatility is improved, but the device complexity and magnetic field interference increase
Solution Approach 1:
The triple camera device is divided into three independent camera modules (first, second, and third camera devices), each capable of independent operation, allowing versatile image capture while maintaining modular simplicity
Solution Approach 2:
Each camera device in the triple configuration is designed to perform multiple functions (photographing different portions, depths, or types of images), reducing the need for additional specialized components and simplifying the overall system
