Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens module is made movable to enable zoom and focus functions, then the functionality and versatility of the device is improved, but the device becomes more susceptible to shaking and produces blurry images
Solution Approach 1:
The patent introduces an optical member (such as a compensating lens or mirror) as an intermediary element that can independently move to counteract the effects of device shaking. This intermediary component compensates for the instability caused by making the lens module movable, thereby maintaining image quality while preserving zoom and focus functionality.
Solution Approach 2:
The patent implements a dynamic stabilization mechanism where the optical member can move in real-time to counteract shaking. By making part of the system dynamically adjustable rather than fixed, the device can adapt to shaking conditions and maintain stable images even when the overall lens module is movable for zoom and focus operations.
2Reliability
If a shockproof mechanism is added to stabilize the lens module, then image quality is improved, but the device complexity increases
Solution Approach 1:
The patent divides the lens module into separate functional segments: a fixed portion containing the main lens structure and a movable portion containing the optical member for stabilization. This segmentation allows the shockproof mechanism to be localized to specific components rather than requiring stabilization of the entire lens assembly, thereby reducing overall structural complexity.
Solution Approach 2:
The patent employs a nested structure where the movable optical member is positioned within or alongside the fixed lens module. The optical member can be nested within the optical path of the main lens, allowing the stabilization mechanism to be integrated into the existing lens structure rather than adding external components, thus minimizing increases in device complexity.
3Reliability
If the circuit assembly uses a rigid structure to maintain electrical connections, then connection reliability is improved, but the device cannot accommodate the movable optical member
Solution Approach 1:
The patent replaces rigid circuit board structures with flexible circuit assemblies that can bend and deform as the optical member moves. These flexible circuits maintain reliable electrical connections through their inherent flexibility, allowing the circuit assembly to accommodate the movable optical member without compromising connection stability.
Solution Approach 2:
The patent transitions from a static, rigid circuit structure to a dynamic flexible circuit assembly that can adapt its shape during operation. The flexible circuit maintains electrical connectivity while dynamically adjusting to the movement of the optical member, enabling both connection reliability and movement capability.
