Solution Overview

Problem

Existing cooking appliance control panels often have tightly packed control elements that are difficult to operate due to their small size and proximity, leading to a cluttered and confusing interface, which can hinder user experience and increase the risk of accidental activation of controls.

Innovation Solution

The design features a control panel with control elements arranged closely together, with a maximum distance of less than 5 cm between adjacent elements, and a user interface that includes a display above the control panel to support operation without obstructing the display, along with signaling means integrated into the control elements for clear acknowledgment of actuations, enhancing clarity and simplicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If control elements are arranged closely together to reduce overall device size, then device compactness is improved, but ease of operation deteriorates due to small size and proximity of control elements

Engineering Contradiction:
Improveoverall device sizeVSAvoidease of operation
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The control panel utilizes a horizontal arrangement of control elements along the width of the door rather than stacking them vertically, effectively using the lateral dimension to accommodate multiple controls without increasing vertical space requirements. This allows control elements to be spaced adequately for easy operation while maintaining a compact overall device footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If control elements are made large for easy operation, then ease of operation is improved, but device complexity increases due to more components and installation space requirements

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple control elements are integrated into a single control panel assembly that is mounted as one unit on the door. The control elements share common mounting structures, wiring harnesses, and housing, reducing overall device complexity despite having multiple individual controls. The integrated design minimizes the number of separate components and simplifies installation.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If control elements are placed close together to save space, then installation space is reduced, but clarity of interface deteriorates leading to confusing operation

Engineering Contradiction:
Improveinstallation spaceVSAvoidinterface clarity
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

Different regions of the control panel are designed with different characteristics - the control elements are positioned in areas with adequate spacing for clarity, while the overall panel utilizes the available horizontal space efficiently. The control elements themselves have localized features such as symbols and labeling that provide clear identification without requiring increased distance between controls.

Inventive Principle:
Principle #3Local quality
