Solution Overview

Problem

Large-scale kitchen cooking containers face challenges with lids that are difficult to manage due to their size and weight, requiring manual placement and often needing to be tracked for specific opening states during different cooking processes.

Innovation Solution

A cooking apparatus with a pivotally connected lid device, a hinge device for easy opening and closing, and a detection device within the hinge housing to monitor the lid's opening state, ensuring reliable and low-maintenance operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lid device is manually placed on the pot device, then the opening state can be controlled, but the operation becomes difficult and time-consuming due to the size and weight of the lid

Engineering Contradiction:
Improveease of lid placementVSAvoidtime for lid placement
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The lid device is converted from a static manually-placed component to a dynamically movable one through the hinge device. The hinge enables the lid to be quickly opened and closed by simple pivoting motion, transforming the operation from manual placement to dynamic control, thereby improving ease of operation and reducing time loss.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the detection device is placed outside the hinge housing, then it can easily detect the lid opening state, but it becomes vulnerable to external influences and requires more maintenance

Engineering Contradiction:
Improvereliability of detectionVSAvoidmaintenance requirement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The detection device is nested inside the hinge housing, placing it within the protected internal space of the hinge mechanism. This nesting protects the detection device from external influences such as moisture, heat, and physical damage, thereby improving reliability while reducing maintenance requirements as the protected environment prevents degradation.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If multiple cooking containers are used in parallel, then productivity increases, but tracking the opening states of multiple lids becomes complex and error-prone

Engineering Contradiction:
Improvecooking capacityVSAvoidtracking of lid states
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The detection device provides automatic feedback about the lid opening state to the control device. This feedback mechanism eliminates the need for manual tracking by operators, allowing multiple cooking containers to be monitored simultaneously without increasing complexity or error rates, thereby supporting increased productivity while maintaining accurate information about each lid's state.

Inventive Principle:
Principle #23Feedback
