Solution Overview

Problem

Existing cooking appliances face challenges in accurately and easily aligning the water tank with the opening hole, leading to misalignment and compromised appearance quality due to manual alignment difficulties and exposure of fastening elements.

Innovation Solution

A cooking appliance design featuring a guide member with a first guide coupled to the water supply device and a second guide coupled to a protrusion on the front panel, along with a fixer that aligns and fixes the guide member to the cavity, ensuring precise alignment and easy operation without exposed fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual alignment method is used to align water tank with opening hole, then alignment can be performed, but alignment accuracy is low and time-consuming

Engineering Contradiction:
Improvealignment accuracyVSAvoidalignment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The guide member is pre-installed on the front panel with the guide hole positioned at the correct location. This preliminary positioning action eliminates the need for manual alignment during water tank installation, as the guide member automatically directs the water tank to the correct position through its guide hole, thereby improving alignment accuracy and reducing alignment time.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If fastening elements are exposed to secure water supply device, then structural stability is improved, but appearance quality deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidappearance quality
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The fastening elements are extracted from the visible front area and relocated to the rear side of the front panel. The guide member is secured to the rear surface of the front panel using fastening elements, which are thus hidden from external view. This maintains structural stability while preserving appearance quality by removing the visual distraction of exposed fasteners.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If water tank is made movable for easy withdrawal, then ease of operation is improved, but alignment maintenance becomes difficult

Engineering Contradiction:
Improvewithdrawal easeVSAvoidalignment maintenance
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The guide member with its precisely positioned guide hole is installed beforehand on the front panel. This preliminary action creates a reusable alignment reference that automatically guides the water tank to the correct position every time it is inserted or withdrawn. The guide hole serves as a consistent reference point that maintains alignment accuracy across multiple operations without requiring re-alignment.

Inventive Principle:
Principle #10Preliminary action
