Solution Overview

Problem

The existing heating cooking apparatus requires time and effort to adjust the arrangement of the pull-out body to prevent electric wave leakage, as the housing needs to be removed and the pull-out body is adjusted in a specific state.

Innovation Solution

A heating cooking apparatus with a pivotally supported angle adjustment member and fastening mechanism that allows for easy adjustment of the pull-out body's angle relative to the heating cooking chamber, ensuring effective sealing without the need to remove the housing, using a shaft member and elongate regulating holes for precise alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the arrangement of the pull-out body is adjusted in a state where the housing is removed and the pull-out body is pulled out, then the pull-out body can be adjusted to prevent leakage of electric waves, but it takes time and effort to adjust the arrangement

Engineering Contradiction:
Improvesealing performanceVSAvoidadjustment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention introduces a pivotally supported angle adjustment member that enables dynamic adjustment of the pull-out body's angle relative to the heating cooking chamber. This allows the sealing surface to be adjusted to the appropriate angle without removing the housing, resolving the contradiction between achieving proper sealing and minimizing adjustment time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the adjustable parameter from positional adjustment (requiring housing removal) to angular adjustment (achievable with housing in place). The angle adjustment member allows modification of the pull-out body's angular parameter while maintaining its installed position, thereby reducing adjustment time while ensuring proper sealing.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If the pull-out body is adjusted with the housing in place, then adjustment time is reduced, but the sealing precision may be insufficient

Engineering Contradiction:
Improveadjustment timeVSAvoidsealing precision
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The pivotally supported angle adjustment member provides dynamic angular adjustment capability, allowing precise control of the pull-out body's angle relative to the heating cooking chamber. This enables accurate sealing adjustment while the housing remains in place, simultaneously achieving time efficiency and sealing precision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention segments the adjustment function into independent angular adjustment components (angle adjustment member with pivot support) that can be adjusted separately from the housing installation. This segmentation allows precise angular positioning to be achieved without compromising overall sealing precision.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a fixed arrangement of the pull-out body is used, then the structure is simple, but it cannot adapt to dimensional variations to prevent electric wave leakage

Engineering Contradiction:
Improvestructural complexityVSAvoidadjustability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The invention replaces fixed arrangement with a dynamically adjustable angle adjustment member that is pivotally supported. This allows the pull-out body to adapt to dimensional variations and achieve proper sealing, while the regulatory hole and fastening member maintain relatively simple structural implementation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The angle adjustment member serves multiple functions: it provides angular adjustment capability, enables adaptation to dimensional variations, ensures proper sealing, and maintains structural simplicity through the regulatory hole and fastening member mechanism. This multi-functionality resolves the contradiction between simplicity and adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
