Modular Lens Cap-Case with Plate Coupling for Dual Protection and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to provide a single device that effectively protects and stores optical camera accessories like filters and lenses both when they are coupled with a camera and when they are uncoupled, as they either serve as protective cases or lens caps but not both simultaneously.
Innovation Solution
A modular lens cap-case design featuring a plate with coupling means that allows it to function as both a protective lens cap and a storage case, with a cavity housed within a base and sidewalls that can be configured to house and secure optical elements, enabling easy installation and removal, and providing protection when coupled with a camera.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate protective case and lens cap are used, then protection and storage functions are provided, but device complexity increases and portability decreases
Solution Approach 1:
The patent combines a protective case and lens cap into a single integrated device. The case includes a cavity that can hold a lens cap, and the lens cap can be positioned in two states: covering the cavity opening when stored, or positioned within the cavity when in use. This merging eliminates the need for separate protective case and lens cap components.
Solution Approach 2:
The integrated device performs multiple functions: it serves as both a protective case for storing the lens cap and as a lens cap itself when the cap is positioned to cover the cavity opening. The case structure universally accommodates both storage and protective functions through its dual-position design.
2Ease of operation
If a modular design with plate coupling means is used, then ease of operation improves, but device complexity increases
Solution Approach 1:
The device is divided into modular components: a case, a lens cap, and a plate with coupling means. The plate can be coupled to the case through plate coupling means, allowing easy assembly and disassembly. This segmentation enables independent replacement and easy operation while maintaining a relatively simple overall structure.
3Device complexity
If a single device performs both protective case and lens cap functions, then device complexity decreases, but adaptability to different usage scenarios is limited
Solution Approach 1:
The lens cap is designed with dynamic positioning capability, allowing it to be positioned in two distinct states: covering the cavity opening when the device is stored, or positioned within the cavity when in use. This dynamic adaptability enables the single device to respond to different usage scenarios without increasing component count.
