Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera lens caps do not provide adequate security against unauthorized access, leading to theft of valuable camera lenses.
Innovation Solution
A locking cap system comprising a base cap, locking ring, spring ring, and top ring, with a locking mechanism that includes a pin and ramps, and an optional automated version with a circuit board and actuating device for controlled locking and unlocking, ensuring secure attachment to the camera lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional camera lens cap is used, then the lens is protected from dust, but the lens remains vulnerable to unauthorized access and theft
Solution Approach 1:
The locking cap is divided into multiple functional components: a base cap for mounting, a locking ring with locking mechanism, and a removable cap portion. This segmentation allows each component to perform its specific function while maintaining overall security without excessive complexity
Solution Approach 2:
The locking mechanism is pre-configured with springs and locking elements that are ready to engage immediately when the cap is attached to the lens, providing security before any unauthorized access attempt occurs
2Reliability
If a locking mechanism is added to the lens cap, then security against theft is improved, but the ease of operation is reduced
Solution Approach 1:
The locking mechanism incorporates springs that automatically engage locking elements when the cap is attached to the lens, and automatically disengage when the cap is removed, eliminating the need for manual locking or unlocking operations
Solution Approach 2:
The manual locking mechanism is replaced with an automated spring-based system that uses elastic potential energy storage and release to perform locking and unlocking functions automatically, reducing operational complexity
3Reliability
If an automated locking mechanism with circuit board is implemented, then security control is enhanced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The circuit board serves multiple functions: controlling the locking mechanism, providing power management, and enabling remote operation capabilities. This multi-functionality justifies the added complexity by consolidating control systems into a single integrated component
Solution Approach 2:
The circuit board acts as an intermediary between the user interface and the mechanical locking mechanism, translating user commands into appropriate mechanical actions while providing a layer of control and security management
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The locking cap effectively prevents unauthorized access to the camera lens by securely attaching to the rear mounting key, providing a high level of security against theft.
Implementation Method 1
a spring ring, and a top ring... the spring ring is positioned between the locking ring and the top ring

AI summary
A locking cap and automated locking cap for coupling to a rear mounting key of a camera lens are disclosed. The locking cap can include a base cap, locking ring, spring ring, shim ring, and top ring. The locking ring includes a locking mechanism and tab for activating the locking mechanism. The tab allows a user to rotatably slide the locking ring to activate or deactivate the locking mechanism. The automated locking cap can include a circuit board and actuating device in communication with the circuit board, which is programmed to receive signals from a user and to transmit the signals to the actuating device. The actuating device includes a retractable pin that inserts into and retracts from a through-hole the top ring, the spring ring, and the locking ring upon receiving the respective signal from the user, which allows the user to activate or deactivate the locking mechanism.
