Removable Vessel Grip Latch With Guided One-Motion Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting parts for boiling or frying vessels require a two-part operating motion for removing the grip part, making it difficult for users to intuitively understand the function, especially when the actuation element is withdrawn along the longitudinal axis, as the grip part can only be detached by tilting the support part upward.
Innovation Solution
A fitting part design that includes a support part and a grip part with a latching device, featuring a latching nib and a motion guide element with an obliquely inclined motion guide surface, allowing the grip part to be tilted back and removed after unlatching, coupling the unlatching motion with the back-tilting motion through a cinematic coupling, ensuring intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grip part is fixed by a downward tilting motion with a latching device, then the reliability of attachment is improved, but the ease of operation deteriorates due to the two-part operating motion required for removal
Solution Approach 1:
The patent combines the unlatching action and the upward tilting motion into a single integrated operation. The actuation element is designed so that pulling it automatically initiates the upward tilting of the grip part while simultaneously releasing the latching device, merging two previously separate actions into one intuitive motion.
Solution Approach 2:
The latching device is designed to automatically begin the unlatching process as soon as the actuation element is pulled, preparing the system for removal before the user completes the upward tilting motion. This preliminary action reduces the effort and cognitive load required from the user.
2Device complexity
If the actuation element is withdrawn along the longitudinal axis, then the device complexity is reduced, but the ease of operation worsens because users intuitively expect the grip part to be removable in the same direction
Solution Approach 1:
The patent utilizes the upward tilting dimension to achieve grip part removal. When the actuation element is pulled along the longitudinal axis, it triggers a mechanism that allows the grip part to tilt upward, creating a new dimension of motion that resolves the conflict between simple actuation and intuitive operation.
Solution Approach 2:
The latching device acts as an intermediary mechanism between the actuation element and the grip part. It translates the linear pulling motion of the actuation element into the upward tilting motion of the grip part, mediating between the simple actuation and the intuitive removal expectation.
3Reliability
If a latching device with actuation element is used, then the reliability of preventing unwanted detachment is improved, but the device complexity increases
Solution Approach 1:
The latching device is designed to automatically latch when the grip part is tilted downward into position, without requiring separate user action. The system serves itself by using the natural tilting motion to engage the latching mechanism, reducing complexity while maintaining reliable detachment prevention.

AI summary
A fitting part includes a support part fastenable to the vessel wall of a boiling or frying vessel and comprises a grip part fastenable to the support part and fixed with a latching device, and a manual actuation element provided on the latching device for unlatching the latching device from a latched position, wherein a latching nib is provided on the support part and is gripped from behind by a complementarily formed latching projection of the grip part during downwardly direction tilting motion and fixes the grip part in position on the support part, wherein a motion guide element with a motion guide surface is provided on the actuation element, and the motion guide surface inclines at an acute angle obliquely against a linear travel path and glides on the contact area when the actuation element is displaced along the travel path.
