Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If magnetic elements and coils are used in the driving assembly, then the optical element can be driven to move for focusing adjustment, but operational errors caused by magnetic interference increase
Solution Approach 1:
The patent introduces a non-magnetic driving mechanism (such as electromagnetic or acoustic wave driving) as an intermediary to replace direct magnetic element interaction. This mediator drives the optical element without causing magnetic interference, thus maintaining focusing adjustment capability while eliminating operational errors caused by magnetic interference
2Stability of the object's composition
If the internal structure is stabilized, then optical quality becomes more stable, but the flexibility to adjust for different photography needs decreases
Solution Approach 1:
The patent divides the internal structure into fixed portions (for stability) and movable portions (for adjustability). The fixed part maintains structural stability and optical quality, while the movable part enables focusing adjustment for different photography needs, resolving the contradiction between stability and flexibility
3Measurement precision
If the driving assembly with multiple magnetic elements is implemented, then precise control of optical element position is achieved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical magnetic element arrangements with a simpler electromagnetic or acoustic wave driving system. This substitution maintains precise position control capability while significantly reducing structural complexity and the number of components required
