Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional angle adjustment mechanisms are used for camera accessories, then the structure becomes complex and heavy, but the angle adjustment flexibility and precision are insufficient
Solution Approach 1:
The adjustment assembly is divided into multiple independent components: first adjustment shaft, second adjustment shaft, regulating part with first and second adjusting portions. Each component performs a specific function, allowing independent adjustment of different parameters, thereby achieving flexible angle adjustment without requiring a complex integrated mechanism
Solution Approach 2:
The first and second connectors are designed with universal mounting interfaces that can accommodate various camera accessories such as matte box kits. The adjustment assembly provides multi-directional angle adjustment capabilities, making the device adaptable to different shooting requirements and accessory types
2Measurement precision
If traditional angle adjustment mechanisms are used for camera accessories, then the weight increases, but the angle adjustment precision is insufficient
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with a more efficient mechanism using adjustment shafts with regulating parts. The shafts rotate within connectors to change spacing, providing precise angle control through simpler rotational motion rather than complex mechanical linkages, thereby reducing weight while improving precision
Solution Approach 2:
The adjustment mechanism changes the spacing parameter between the first and second connectors by rotating the adjustment shafts. This parameter change directly controls the angle of the mounted accessory, providing precise adjustment capability. The system allows continuous variation of the spacing parameter to achieve different angle positions
3Measurement precision
If complex adjustment mechanisms are used, then angle adjustment precision improves, but the ease of operation and component replacement deteriorates
Solution Approach 1:
The adjustment assembly is segmented into independent, modular components that can be easily assembled and disassembled. The first and second connectors can be separated for component replacement, while the adjustment shafts remain positioned within their respective connectors, facilitating maintenance and accessory changes without requiring complete disassembly of the adjustment mechanism
Solution Approach 2:
The adjustment shafts are pre-positioned within the connectors during assembly, with their rotation axes aligned to the connector centers. This preliminary positioning ensures that when components need to be replaced or adjusted, the shafts are already in their correct locations, simplifying the operation of component replacement while maintaining precise angle adjustment capability
