Solution Overview

Problem

Microwave oven user interfaces are often difficult to use and confusing, and existing roller support mechanisms for glass platters can be problematic, especially when foods need to be covered and vented during cooking.

Innovation Solution

A microwave oven with an improved user interface featuring first and second input selector elements, a display element, and a processor module that allows for toggle between operating modes, including shortcut selectors for predefined cooking profiles, and a soft close apparatus for the door mechanism to prevent interference with stacking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional user interfaces with multiple dials and buttons are used, then comprehensive cooking control is achieved, but the interface becomes difficult to use and confusing

Engineering Contradiction:
Improveuser interface ease of useVSAvoiduser interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The user interface is segmented into multiple operating modes (first operating mode for basic cooking, second operating mode for simplified cooking). Each mode presents a simplified subset of controls and functions, allowing users to choose the appropriate level of complexity for their needs. The processor module toggles between these modes based on user selection, effectively dividing the complex interface into manageable segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The user interface dynamically changes its configuration based on the selected operating mode. In the first operating mode, the interface displays detailed controls for power and time settings. In the second operating mode, the interface simplifies to show only essential cooking parameters. This dynamic reconfiguration allows the same physical interface to serve multiple complexity levels without requiring additional hardware.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If shortcut selectors for predetermined cooking profiles are added, then cooking simplicity is improved, but the selectors are hidden behind the door and less accessible

Engineering Contradiction:
Improvecooking profile selection easeVSAvoidselector accessibility
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The shortcut selectors are positioned on the door surface, utilizing the vertical dimension of the door as a control surface. This allows the selectors to be integrated into the door structure itself, making them accessible during door operation while maintaining a compact overall design. The selectors are arranged vertically on the door, allowing users to access them naturally when opening or closing the door.

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

3Adaptability or versatility

If real-time adjustment of power and time settings is enabled, then cooking flexibility is improved, but the interface becomes more complex to operate

Engineering Contradiction:
Improvecooking parameter adjustabilityVSAvoidinterface operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The interface dynamically adapts its functionality based on the selected operating mode. In the first operating mode, real-time adjustment of power and time settings is fully enabled, providing maximum flexibility for experienced users. In the second operating mode, the interface locks certain parameters and provides predefined cooking options, simplifying operation for users who prefer automatic control. This dynamic behavior allows the system to cater to different user skill levels and preferences.

Inventive Principle:
Principle #15Dynamics

AI summary

A user interface for a microwave oven. The user interface including: a power input element for receiving user input to adjust a cooking power setting; a time input element for receiving user input to adjust a cooking time setting; a display element for displaying the cooking power setting and the cooking time setting; and a processor module that receives a first signal from the power input element that is indicative of an adjustment to a cooking power setting and a second signal from the time input element that is indicative of an adjustment to a cooking time setting; the processor being coupled to the display element to cause the display to present the user selected cooking power setting and the user selected cooking time setting; wherein: upon commencing a cooking cycle, user input applied to the power input module caused the user selected cooking power setting to be adjusted. The user interface can further include: a plurality of shortcut selection elements, each shortcut selection element is associated with a predetermined cooking profile having predetermined cooking settings. T he user interface can further include: an "a bit more" selection element that causes calculation of a supplemental cooking setting.
