Camera End Stop Bumper Cushioning Suspension Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small form factor cameras face challenges in cushioning movement to prevent collisions with lateral end stops, which can damage the camera and impact performance, and in managing electrostatic charge accumulation.
Innovation Solution
Incorporating end stop bumpers as part of a suspension spring structure that interfaces with a stationary structure to cushion the movement of the suspension platform before it reaches a lateral end stop, thereby preventing collisions and reducing electrostatic charge accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suspension platform moves freely to accommodate optical stabilization and autofocus mechanisms, then camera performance is improved, but the risk of collision with lateral end stops increases causing damage and electrostatic charge accumulation
Solution Approach 1:
The patent applies beforehand cushioning by positioning end stop bumpers between the suspension platform and lateral end stops before any collision can occur. These bumpers absorb movement and cushion the suspension platform's approach to the end stops, preventing direct impact and the associated damage and electrostatic charge accumulation while maintaining the platform's freedom of movement for optical stabilization and autofocus operations
2Reliability
If end stop bumpers are added to prevent collisions, then protection against damage is improved, but device complexity increases
Solution Approach 1:
The patent merges the end stop bumpers with the existing suspension spring structure, integrating the protective function into the already-present mechanical framework. This combining approach adds collision protection while minimizing the increase in device complexity by reusing existing structural elements rather than adding completely separate components

AI summary
Various embodiments include a camera having one or more end stop bumpers. In some embodiments, the end stop bumper(s) may be at least partially disposed between a suspension platform of a camera and a lateral end stop defined by a stationary structure of the camera. The end stop bumper(s) may be configured to cushion movement of the suspension platform as the suspension platform approaches the lateral end stop. In some embodiments, the end stop bumper(s) may be part of a suspension spring structure coupled to the suspension platform.
