Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The contact between movable and fixed components in existing optical stabilization structures is unstable due to varying contact positions or areas, affecting the optical stabilization performance.
Innovation Solution
The optical stabilization structure features a fixing component with an accommodating space and a movable component that contacts the fixing component through point contact, with the abutting surface being slidable relative to the contact surface, enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If arc surfaces are used for contact between movable and fixed components, then the structure is simple and easy to manufacture, but the contact position and contact area become unstable during operation
Solution Approach 1:
The patent applies spheroidality by designing the contact surface of the movable component as a spherical surface that contacts the fixed component at a single point. This curved surface configuration ensures stable point contact during movement, resolving the instability issue of arc surface contact while maintaining manufacturing feasibility through standard spherical machining processes.
2Reliability
If point contact is implemented between movable and fixed components, then contact position and contact area are stabilized, but the structure becomes more complex
Solution Approach 1:
The patent applies local quality by implementing point contact only at the specific contact surface between the movable and fixed components, while other parts of the components maintain simpler structures. The spherical contact surface is localized to where stability is needed, avoiding unnecessary complexity in the overall device structure.

AI summary
An optical stabilization structure, which includes a fixing component and a movable component, is disclosed. The fixing component provides an accommodating space, and includes a bottom plate and a first annular sidewall. The bottom of the first annular sidewall is orthogonally connected to the bottom plate to constitute the accommodating space, and an inner sidewall of the first annular sidewall has a contact surface. The movable component includes a second annular sidewall disposed in the accommodating space, wherein an outer sidewall of the second annular sidewall has an abutting surface, the abutting surface matches the contact surface by point contact, and the abutting surface is configured to be slidable relative to the contact surface. Through the contact manner of the movable component and the fixing component, the contact position, area and force of the optical stabilization structure are more stable to achieve the purpose of enhancing product performance.
