Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-lens system (three-lens or four-lens) is used to achieve high-magnification effects, then the optical functionality is improved, but the device complexity and unit price increase significantly
Solution Approach 1:
The patent divides the lens system into a fixed main lens and a separable external lens that can be attached or detached. This segmentation allows the device to function as a single-lens camera in normal mode while enabling multi-lens functionality when the external lens is attached, thus reducing overall device complexity while maintaining optical versatility.
Solution Approach 2:
The patent implements a dynamic lens system where the external lens can be attached or detached based on usage needs. The magnetic adsorption mechanism allows for easy attachment and detachment without professional alignment tools, enabling the system to adapt between single-lens and multi-lens configurations dynamically.
2Adaptability or versatility
If a plug-in external lens is used to achieve high-magnification effects, then the optical functionality is improved, but the size and weight of the lens increase, making it cumbersome to carry and store
Solution Approach 1:
The patent uses magnetic adsorption force to counteract the weight of the external lens during attachment. The magnetic force between the positioning magnets and magnet sealing iron shell holds the external lens in place without requiring mechanical fasteners or increasing the lens structure's weight, thus reducing the overall burden on the user.
3Ease of operation
If positioning magnets are used for lens attachment, then the ease of operation is improved, but magnetic field interference with the electronic device may occur
Solution Approach 1:
The patent extracts the magnetic field from the internal structure of the lens by using a magnet sealing iron shell and magnet sealing iron plate. These components contain and guide the magnetic field lines, confining them to specific pathways that pass through the positioning magnets and sealing structures, thereby preventing magnetic field leakage and interference with the electronic device while maintaining easy lens attachment through magnetic adsorption.
4Manufacturing precision
If professional optical axis alignment adjustment is required for lens installation, then the manufacturing precision is improved, but the ease of operation deteriorates, requiring continuous adjustment without professional background
Solution Approach 1:
The patent implements a self-aligning lens attachment mechanism where the positioning magnets and positioning concave holes automatically align the external lens with the main lens when the lens is attached. The magnetic adsorption force guides the lens into the correct position, and the positioning structure maintains optical axis alignment without requiring user adjustment or professional knowledge, thus enabling ordinary users to install lenses easily while maintaining manufacturing precision.
