Camera Protection Device with Integrated Light Shielding Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phone camera lenses are prone to damage, and lens protection films interfere with the flash lamp, causing image quality issues, especially in night scenes.
Innovation Solution
A camera protection device with a light shielding structure integrated into a sheet body that fits around the camera and flash lamp, preventing light from entering the lens protection film and protecting the camera from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lens protection film is attached to protect the camera lens, then the camera is protected from damage, but the flash lamp light interferes with the lens protection film causing image quality degradation
Solution Approach 1:
The protection device is segmented into multiple functional layers: a transparent protective sheet for physical protection, and a separate light shielding layer with specific aperture patterns to control light interference. This segmentation allows each layer to independently perform its function without compromising the other.
Solution Approach 2:
The light shielding layer implements local quality by having different optical properties in different regions - opaque shielding material in areas where light must be blocked, and transparent or aperture regions where light must pass through to the lens. This localized differentiation resolves the contradiction between protection and image quality.
2Manufacturing precision
If a light shielding structure is added to prevent flash interference, then image quality is improved, but the device structure becomes more complex
Solution Approach 1:
The light shielding layer is merged with the protective sheet to form an integrated camera protection device. The light shielding layer can be coated directly on the protective sheet or embedded within it, combining the protective and light-controlling functions into a single unified structure that reduces overall system complexity.
Solution Approach 2:
The protective sheet serves multiple functions: it provides physical protection for the lens while also serving as the substrate for the light shielding layer. The light shielding layer itself performs both light blocking and light guiding functions through its aperture pattern design, achieving multi-functionality with minimal additional components.
