Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional image stabilizing devices use guiding shafts to support the correction lens holding frame, then the device can maintain image stabilizing performance, but the device dimensions increase and miniaturization becomes difficult
Solution Approach 1:
The patent removes the guiding shafts from the image stabilizing device configuration. Instead of using separate guiding shafts to support the correction lens holding frame, the invention integrates the support function directly into the holding frame structure itself, thereby eliminating unnecessary components and reducing device dimensions while maintaining image stabilizing performance
Solution Approach 2:
The correction lens holding frame is designed to perform multiple functions simultaneously: it holds the correction lens, provides structural support, and enables both rectilinear movement and rotation without requiring separate guiding shafts. This multi-functional design reduces the overall device complexity and size
2Ease of manufacture
If conventional image stabilizing devices apply driving forces to separate components, then the driving mechanism can be simple, but the device requires more space and has increased dimensionality
Solution Approach 1:
The patent combines the rectilinear movement and rotation driving functions into a single integrated driving mechanism that directly acts on the correction lens holding frame. By merging these functions and applying driving forces directly to the holding frame, the invention reduces the space required for the driving mechanism while maintaining manufacturing simplicity
3Ease of manufacture
If conventional image stabilizing devices use adhesion processes for assembly, then components can be joined, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The patent eliminates adhesion processes from the manufacturing procedure. Instead of using adhesives to join components, the invention employs mechanical fitting and precise geometric interlocking between parts, which simplifies the manufacturing process and reduces production complexity while maintaining assembly capability
Solution Approach 2:
The invention replaces chemical bonding (adhesion) with mechanical bonding methods. The components are designed with complementary geometric features that provide secure mechanical attachment without requiring adhesive materials or complex bonding processes
