Pressure-Sensitive Button Lock for Child-Resistant Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers often lack effective and unobtrusive locking mechanisms that can securely prevent access by children, especially in containers with preexisting dimensions or geometric features that are not conducive to traditional internal locking mechanisms.
Innovation Solution
A pressure-sensitive locking mechanism comprising a first tine, a second tine with a configurable locked and unlocked state, and a joining segment, where the second tine includes a tab that converts between locked and unlocked states upon pressure application and release, integrated into a container tray with a sleeve for secure and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are integrated into container internals, then security against children is improved, but storage space is reduced and adaptability to preexisting containers is worsened
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking element with tines that can be inserted into a receiving structure, and a actuator mechanism. This segmentation allows the lock to be designed as a modular assembly that can be fitted within existing container spaces without requiring a complete redesign of the container interior.
Solution Approach 2:
The locking mechanism utilizes the vertical dimension by having the locking element extend upward from the container bottom surface, with tines reaching into a receiving structure at the top. This vertical arrangement maximizes the use of available height while minimizing horizontal space occupation, thereby preserving storage volume.
2Reliability
If traditional locking mechanisms are integrated into container internals, then security against children is improved, but ease of fitting to preexisting containers is worsened
Solution Approach 1:
The locking mechanism is designed with universal adaptability through a standardized receiving structure that can accommodate various container configurations. The actuator mechanism can be integrated with different container types (storage bins, organization containers, etc.) by adjusting the positioning of the locking element relative to the container walls, making it suitable for preexisting containers with different dimensions and geometries.
3Reliability
If an external lock is used on the container, then security against children is improved, but device complexity increases and usable storage space decreases
Solution Approach 1:
The locking mechanism is merged with the container structure itself rather than being a separate external component. The locking element integrates with the container bottom and walls, and the actuator mechanism is combined with existing container features such as handles or side panels. This integration reduces overall device complexity by eliminating the need for separate external locks and mounting hardware.
Solution Approach 2:
The locking mechanism is designed to be self-contained with the locking element, actuator, and receiving structure all forming an integrated assembly that requires no additional external components. The mechanism serves its own locking function through this integrated design, reducing complexity compared to external locks that require separate mounting brackets, screws, and fasteners.
4Reliability
If the locking mechanism is made secure and child-resistant, then security is improved, but ease of operation by users is worsened
Solution Approach 1:
The locking mechanism incorporates a spring-loaded actuator that provides dynamic response to user input. When the user applies force to the actuator, a cam mechanism converts this motion into the appropriate force to disengage the locking element. The spring provides automatic return to the locked state, creating a dynamic system that is both secure (requiring deliberate action to unlock) and easy to operate (with smooth, responsive actuation).

AI summary
The invention of the present disclosure may be a pressure sensitive locking mechanism comprising a first tine, a second tine, and a third tine. The locking mechanism may further comprise a tab disposed on the second tine, where the tab may be orthogonal to the second tine. In an embodiment, the second tine is configurable in a locked state and an unlocked state, where the second tine comprises a second tine bell disposed on the lower portion of the second tine, and where the second tine bell is tapered from the tab to an upper portion of the second tine. The tab may be configured to receive a pressure, application of the pressure may be configured to convert the second tine from the locked state to the unlocked state, and withdrawal of the pressure may be configured to convert the second tine from the unlocked state to the locked state.
