Replaceable Lens Module With Movable Housing for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture devices face issues with lens misalignment and damage due to impacts, making it difficult to replace individual lenses and often requiring replacement of the entire device.
Innovation Solution
A replaceable lens module with a housing and biasing element that allows for easy lens replacement and alignment, and absorbs impact forces to protect internal lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the lens is connected within the image capture device to maintain alignment, then proper alignment is achieved, but the lens becomes vulnerable to misalignment and damage when the device is dropped or impacted
Solution Approach 1:
The lens assembly is divided into separate components: the lens barrel containing the lens and the housing. This segmentation allows the lens to be protected from impact forces by the movable housing while maintaining precise alignment through the bayonet coupling mechanism when properly assembled.
Solution Approach 2:
The housing is designed to be movable relative to the lens barrel, creating a cushioning effect that absorbs impact forces before they can reach the lens. This preliminary protection prevents misalignment and damage while maintaining alignment during normal operation through the biasing element.
2Manufacturing precision
If the lens is connected within the image capture device to maintain alignment, then proper alignment is achieved, but replacement of damaged lenses becomes difficult and may require replacement of the entire device
Solution Approach 1:
The lens assembly is segmented into the lens barrel (containing the lens) and the housing, which can be replaced independently. The bayonet coupling mechanism enables easy attachment and detachment of the lens module, allowing replacement of only the damaged lens component rather than the entire device.
Solution Approach 2:
The lens module is designed as a replaceable component that can be easily removed and replaced. When the lens is damaged, only the lens module needs to be discarded and replaced, while the housing and other components are recovered and reused, reducing waste and repair costs.
3Reliability
If the housing is made movable to absorb impact forces, then protection from damage is achieved, but the complexity of the device increases
Solution Approach 1:
The housing is designed with movable components that can shift position relative to the lens barrel when impact forces are applied. This dynamic design allows the housing to absorb impact forces while maintaining a simple and compact structure, avoiding excessive complexity through controlled movement rather than complex mechanisms.

AI summary
An image capture device includes a lens barrel disposed in a body of the image device, a bayonet, a replaceable lens module that is configured to releasably couple to the bayonet, and a biasing element coupled to the housing or coupled to the bayonet that is configured to bias the housing against the lens barrel. The replaceable lens module includes a housing and a lens positioned in a lens recess of the housing. Additionally, when an impact force that meets a predetermined threshold is applied to an exterior surface of the replaceable lens module, the housing is configured to compress the biasing element and disengage the lens barrel.
