Cap Device Locking Mechanism for Container Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage containers lack a simple and detachable cap device with high assemblability and compatibility for quantitative discharge of contents, and there is a need to prevent unintentional separation of the cap device from the container to enhance safety and reliability.
Innovation Solution
A cap device with a screw thread coupling mechanism and a locking device using a loop-shaped band with a rotation-preventing protrusion, allowing for easy installation on conventional containers and preventing unintentional detachment, thereby enabling quantitative discharge and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable cap device is installed on a conventional container, then quantitative discharge function and versatility are improved, but the risk of unintentional separation increases
Solution Approach 1:
The locking device applies preliminary anti-action by using a band part that wraps around the container and applies frictional force in advance to prevent the cap device from detaching unintentionally. The locking device is positioned to counteract any forces that might cause separation before they occur.
Solution Approach 2:
The locking device is nested within the cap device structure, with the band part passing through the container and the locking mechanism integrated into the cap assembly. This nested configuration ensures the locking device moves with the cap device while maintaining continuous engagement with the container.
2Reliability
If a locking device with band part is used, then reliability is improved, but device complexity increases
Solution Approach 1:
The band part is implemented as a flexible thin film structure that wraps around the container. This flexible band can conform to the container shape and provides locking force through friction and geometric constraint, avoiding the need for rigid complex mechanical locking structures.
Solution Approach 2:
The band part acts as an intermediary element between the cap device and the container. Instead of directly coupling the cap to the container with complex mechanisms, the band part mediates the connection, providing a simple yet effective locking function through its wrapping and friction-based engagement.
3Productivity
If a pass-through device is added to the cap, then quantitative discharge capability is improved, but manufacturing cost increases
Solution Approach 1:
The cap device is segmented into functional modules: the cap body, the pass-through device, and the locking device. The pass-through device is designed as a separate functional component that can be manufactured independently and then assembled to the cap body, allowing for standardized production and reduced overall manufacturing complexity.
