Vessel Closure Link Guide for Secure Locking and Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for vessels, such as thermos flasks, require significant effort to remove the closure element for filling or cleaning, and often cannot be removed at all, making these processes difficult.
Innovation Solution
A closure device utilizing a link guide with link grooves and sliding blocks that allows the closure element to be easily moved relative to the receiving device, enabling simple removal and adjustment between open and closed positions, facilitated by prestressed sliding blocks that snap into place for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the closure element is securely locked in the receiving device, then the reliability of closure is improved, but the ease of operation for removal deteriorates
Solution Approach 1:
The closure element is designed with dynamic positioning capability, allowing it to be locked securely during use and easily removed when needed. The link guide mechanism enables the closure element to transition between a locked position (where it is securely held) and an unlocked position (where it can be easily removed), resolving the contradiction between secure closure and easy removal.
Solution Approach 2:
The link guide acts as an intermediary mechanism between the closure element and the receiving device. It provides a controlled path that allows the closure element to be securely retained during normal use while enabling easy removal through a specific unlocking motion, thus mediating between the conflicting requirements of security and ease of operation.
2Reliability
If the closure element is tightly fitted in the receiving device, then the reliability of sealing is improved, but the device complexity increases
Solution Approach 1:
The locking function is segmented into separate components: the link guide mechanism and the closure element with link grooves. This segmentation allows the sealing function to be independently optimized through a simple tight fit between the closure element and receiving device, while the locking function is handled by the separate link guide mechanism, reducing overall device complexity.
Solution Approach 2:
The sealing and locking functions are merged into a single integrated design where the closure element simultaneously provides both sealing (through tight fitting) and locking (through the link guide mechanism). This merging eliminates the need for separate complex locking mechanisms, maintaining simplicity while ensuring reliable sealing.

AI summary
The closure device (10) has an opening (15) with a holding element (14) for inserting the closure unit (12). The closure unit is pivotably moved via sliding guide (17) relative to the holding element. The sliding blocks (16) arranged in holding element, are biased in the direction of the slide grooves (22) provided in the closure unit so that the closure unit remains in operation position relative to the holding element while the closure unit is pressed by push back portion provided in sliding blocks. An independent claim is included for vessel.
