Solution Overview

Problem

Existing cooker racks require complex operations to stabilize large cookware, leading to potential soup spilling and safety hazards, especially with fully filled pots, due to fixed limiting structures that necessitate cookware inclination.

Innovation Solution

A movable limiting block system on the cooker rack, allowing cookware to be vertically placed without interference, utilizing a hinged and sliding mechanism with warping plates and reset members for automatic adjustment and stabilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed limiting structure is used to stabilize large cookware, then the cookware position can be stabilized, but the operation complexity increases and cooking efficiency decreases

Engineering Contradiction:
Improvecookware position stabilityVSAvoidcooking efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The limiting block is designed to be movable rather than fixed, allowing it to automatically adjust its position based on the cookware size. When cookware is placed, the limiting block moves to contact the cookware side wall and provides stabilization; when cookware is removed, the limiting block returns to its original position. This dynamic adjustment eliminates the need for manual repositioning operations while maintaining stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The limiting assembly utilizes the weight and position of the cookware itself to trigger the automatic movement of the limiting block. The cookware's placement automatically activates the limiting mechanism through the warping plate connection, eliminating the need for external intervention or complex manual adjustment operations.

Inventive Principle:
Principle #25Self-service

2Reliability

If a fixed limiting structure is used to stabilize large cookware, then the cookware position can be stabilized, but the operation difficulty increases

Engineering Contradiction:
Improvecookware position stabilityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The limiting block transitions from a static fixed structure to a dynamic movable component that automatically responds to cookware placement. The movable design allows the limiting block to freely adjust its position along the guide direction, enabling seamless adaptation to different cookware sizes without requiring users to perform complex inclination or adjustment operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses the cookware's own weight and placement action to automatically trigger the limiting mechanism. When cookware is placed on the rack, its weight causes the warping plate to deform, which automatically moves the limiting block into the stabilizing position, eliminating the need for manual intervention.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the cookware is placed vertically to avoid complex operations, then the operation convenience improves, but the cookware may be unstable without proper limiting

Engineering Contradiction:
Improveoperation convenienceVSAvoidcookware stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The limiting block is designed to move dynamically in response to cookware placement, allowing it to automatically engage with the cookware side wall when vertically placed. The movable mechanism ensures that the limiting block is positioned to provide stabilization exactly when needed, without requiring the cookware to be inclined or manually adjusted.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If a movable limiting block is used to simplify operations, then the operation convenience improves, but the structure complexity increases

Engineering Contradiction:
Improveoperation convenienceVSAvoidlimiting assembly structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The limiting assembly is divided into independent functional components: the limiting block, the warping plate, the installing case, and the reset member. Each component has a specific function and can move or adjust independently. This segmentation allows the complex function of automatic limiting to be achieved through simple, modular interactions between components rather than a single complex mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The warping plate serves as an intermediary element that connects the cookware weight to the limiting block movement. When the cookware is placed, its weight deforms the warping plate, which then translates this deformation into the movement of the limiting block. This intermediary mechanism simplifies the overall structure by using a simple deformable element to mediate between the load and the limiting action.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Disclosed is a cooker rack convenient for accommodating cookware and a cooker. When the cookware is not placed into a support limiting frame, a limiting block is positioned outside a peripheral outer side of the support limiting frame. When the cookware is placed into the support limiting frame, the limiting block moves relative to a cooker rack body until the limiting block is abutted against an outer wall of the cookware, thus ensuring no interference between the cookware and the limiting block when the cookware is vertically placed into the support limiting frame, a user can place the cookware into the support limiting frame more quickly, the operation complexity is reduced, the cooking efficiency and the operation convenience are improved, the food spilling risk is reduced, and meanwhile, the operation safety and convenience are improved.
