Solution Overview

Problem

The increasing number of functions in cooking devices complicates user operation, leading to a higher likelihood of errors for users who do not require all functions, especially those who cannot make sufficient use of the device's features.

Innovation Solution

A cooking device with a selection switch that allows users to choose between a full mode where all control modes are selectable and a simple mode where only necessary control modes are enabled, along with visual notifications to distinguish enabled from disabled switches, reducing operational complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of functions is increased to provide more features (timer function, automatic cooking function), then the functionality and versatility of the cooking device is improved, but the number of switches increases and the operation becomes complicated

Engineering Contradiction:
ImprovefunctionalityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cooking device dynamically changes its operational state based on the selected cooking type. When a cooking type is selected, the control unit enables only the switches relevant to that cooking type and disables others. This dynamic activation/deactivation of switches adapts the device's interface complexity to the current operational context, resolving the contradiction between providing multiple functions and maintaining simple operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If all control modes are always selectable to provide full functionality, then the versatility is improved, but the ease of operation deteriorates for users who only need basic functions

Engineering Contradiction:
Improvecontrol mode availabilityVSAvoidoperational simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the availability of control modes based on the selected cooking type. Only the control modes necessary for the currently selected cooking type are enabled, while others are disabled. This dynamic adaptation allows the device to provide full functionality when needed while maintaining operational simplicity for basic tasks, resolving the contradiction between versatility and ease of operation.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple switches are provided for different functions, then the functionality is improved, but the likelihood of user error increases

Engineering Contradiction:
Improvefunction availabilityVSAvoiduser operation accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The control unit dynamically enables or disables switches based on the selected cooking type, ensuring that only relevant switches are active. This prevents users from accidentally operating irrelevant switches, thereby reducing user errors while maintaining full functionality when needed. The dynamic state change resolves the contradiction between providing multiple functions and ensuring reliable operation.

Inventive Principle:
Principle #15Dynamics

AI summary

There is provided a cooking device including a plurality of switches that is easy to use for users requiring only part of the functions of the cooking device. A cooking device includes a control mode switch (6a, 6c, 6d, 6g) for selecting a control mode for controlling a heating operation; a setting switch (6b, 6e, 6f) for selecting a set value in each control mode; a heating control unit (10) for controlling a heating unit (3) based on the control mode and the set value inputted through the control mode switch and the setting switch; and a selection switch (8a) for selecting the operation mode; wherein the operation modes include a first operation mode in which all of the plurality of control modes are set to be selectable and a second operation mode in which only part of the control modes are set to be selectable; and the heating control unit sets only the control mode switch and the setting switch necessary for the control modes which are set to be selectable in the operation mode selected by the selection switch to be enabled.
