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

VSEngineering 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

Engineering Contradiction:
Improvecontainer storage volumeVSAvoidhandle stability
Core Design Contradiction:
Volume of moving objectVSReliability

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvehandle locking securityVSAvoidnumber of moving parts
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #13The other way round (Inversion)

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

Engineering Contradiction:
Improvehandle position securityVSAvoiddevice durability
Core Design Contradiction:
ReliabilityVSStrength

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveautomatic locking securityVSAvoiduser control simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #5Merging (Combining)

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.
