Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple drive assemblies are used to control multiple optical elements, then image stabilization capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple drive assemblies into a shared structure where common components (immovable part, magnetic elements, coils) serve multiple optical elements simultaneously. The drive assemblies are integrated around a central optical axis, allowing coordinated control of multiple optical elements with reduced structural redundancy.
Solution Approach 2:
The immovable part and magnetic elements serve universal functions across multiple drive assemblies. The same type of coil and magnetic element configuration is reused for different optical elements (first, second, third optical elements), enabling multi-functionality while reducing the number of unique components needed.
2Stability of the object's composition
If drive assemblies are disposed on multiple sides of the polygonal structure, then balance and stability are improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs asymmetric placement of drive assemblies on the polygonal structure, with assemblies positioned on specific sides (first, second, and fourth sides) rather than uniform distribution. This asymmetric configuration achieves structural balance while simplifying manufacturing by reducing the number of identical assembly positions required.
Solution Approach 2:
The drive mechanism is segmented into modular drive assemblies that can be independently manufactured and then assembled onto the polygonal structure. Each drive assembly is a discrete unit that can be produced separately, allowing for simplified manufacturing processes and easier quality control.
3Measurement precision
If sensing assemblies are integrated into the drive assemblies, then movement control precision is improved, but device complexity increases
Solution Approach 1:
The sensing assemblies are merged with the drive assemblies, with sensing elements (such as Hall sensors or capacitive sensors) integrated directly into the coil structures or magnetic element arrangements. This combination allows precise measurement of optical element positions and movements without requiring separate sensing systems.
Solution Approach 2:
The same sensing assembly design is used across multiple drive assemblies, providing universal measurement capability for all optical elements. The sensing elements detect positional information for different optical elements using identical or similar configurations, reducing design complexity while maintaining precision.

Implementation Method 1
the first magnetic element corresponds to the first coil to generate a first driving force
Implementation Method 2
the guidance element guides the accommodation support to move along the first axis
Implementation Method 3
The first holder is driven to move relative to the immovable part around the optical axis, so that the first optical element is driven to move relative to the immovable part
Implementation Method 4
The first sensing element corresponds to the first reference element and disposed inside the first coil
