Solution Overview

Problem

Steam ovens require access to a water tank for filling, which is often located near the heating chamber, necessitating the control panel to be moved without interfering with the oven door, while maintaining continuous cooking functionality.

Innovation Solution

A hinge mechanism allowing the control panel to tilt down non-circularly within its own space, utilizing an oblong cam, pin, pivot pieces, and a latching system with a magnet, enabling the panel to rotate and maintain access to the water tank without interrupting cooking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the control panel is moved to allow access to the water tank, then access to the water tank is enabled, but the control panel may cause mechanical conflict with the oven door

Engineering Contradiction:
Improveaccess to water tankVSAvoidmechanical conflict with door
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control panel is transformed from a fixed component to a dynamic one that can tilt and rotate. The hinge system with oblong cam mechanism enables the control panel to change its position and orientation, allowing it to tilt downward for water tank access while returning to its original position to avoid conflict with the oven door during normal operation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the control panel tilts down for water tank access, then water refilling is enabled, but cooking operation may be interrupted

Engineering Contradiction:
Improvewater refillingVSAvoidcooking continuity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The hinge system is pre-configured with a latch mechanism that automatically secures the control panel in its tilted position. This preliminary action ensures that when the control panel is tilted for water refilling, the cooking operation can continue uninterrupted because the panel remains stable in the tilted position and can be easily returned to its original position afterward.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a simple hinge mechanism is used for the control panel, then the mechanism is robust and reliable, but the control panel may not achieve precise non-circular movement

Engineering Contradiction:
Improvehinge mechanism reliabilityVSAvoidnon-circular movement precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The oblong cam mechanism incorporates curved surfaces and non-circular geometry to achieve the desired non-circular movement of the control panel. The cam's shape is specifically designed to guide the control panel through the precise arc-shaped trajectory needed for tilting down and returning to the original position, combining simplicity with precision.

Inventive Principle:
Principle #14Spheroidality (Curvature)
