Pivoting Cooking Vessel Handle With Integrated Base Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen containers with pivoting handles are unstable and dangerous in the gripping position, and complex locking systems increase manufacturing costs and fragility while providing imperfect security.
Innovation Solution
A kitchen container with a pivoting gripping means featuring a base fixed to the container wall, a pivoting handle, a locking mechanism integrated into the base, and a control member operable by the user, which ensures stable and safe automatic locking and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a pivoting handle is mounted on a kitchen container to reduce storage space, then the container size is reduced and storage is facilitated, but the handle becomes unstable and dangerous in the gripping position
Solution Approach 1:
The patent applies preliminary action by providing a locking means that automatically locks the handle in the gripping position before use. The locking means includes a control element that, when actuated, engages a locking mechanism to secure the handle radially outward, preventing accidental movement before the user begins handling the container.
Solution Approach 2:
The patent implements self-service through an automatic locking mechanism that self-secures the handle in the gripping position. The control element is integrated into the handle structure, allowing the handle itself to engage the locking means on the container wall, creating a self-locking system that maintains stability without external intervention.
2Reliability
If a complex control system with multiple moving parts is added to lock the handle in the gripping position, then the handle stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies segmentation by dividing the locking system into two functional components: a control element integrated into the handle and a locking means mounted on the container wall. This segmentation allows each component to have a simple, dedicated function - the control element provides actuation while the locking means provides secure engagement - reducing overall complexity compared to integrated complex mechanisms.
Solution Approach 2:
The patent uses inversion by reversing the traditional approach: instead of having the handle actively engage a complex locking mechanism, the locking means is mounted on the container wall and passively receives the handle. The control element simply actuates the locking means, which then secures the handle in position, inverting the active-passive relationship to simplify the system.
3Reliability
If a locking means with multiple moving parts is implemented to secure the handle, then the handle stability is improved, but the device becomes more fragile and prone to breakage
Solution Approach 1:
The patent applies extraction by removing the locking mechanism from the handle structure and mounting it separately on the container wall. This extraction eliminates the need for complex internal moving parts within the handle itself, reducing fragility. The locking means on the wall is a separate, robust structure that can be made from durable materials without compromising handle integrity.
4Reliability
If the locking means is mounted on the base and controlled by a control member, then the handle stability and safety are improved, but the ease of operation is reduced
Solution Approach 1:
The patent applies merging by combining the control element with the handle structure itself. The control element is integrated into the handle, allowing the user to actuate the locking mechanism through a single, unified action on the handle. This merging eliminates separate controls and simplifies operation while maintaining the security benefits of the locking means mounted on the base.

AI summary
The container (1) has a pivoting gripping unit (2) pivoting from a radial gripping position relative to a wall (3) of the container to a non-radial rest position and vice-versa. The pivoting gripping unit includes a base fixed on the wall of the container. A gripping handle (6) is mounted on the base to pivot between the gripping and the rest positions. A support plate is mounted on the base in a displaceable manner, where the support plate is controlled by a control unit (8) that is mounted on the base. The support plate locks the handle in the gripping position.
