Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to perform power settings and time settings for oven and microwave functions in household appliances using conventional touch panel display devices, requiring a complex operation and multiple steps.
Innovation Solution
A touch-based operation device with a graphical user interface (GUI) on a full-dot liquid crystal display and capacitance type touch panel, allowing users to set power and time settings by dragging or touching an intersection point on an orthogonal coordinate system, reducing the number of operations needed.

Engineering Contradiction Analysis
1Ease of operation
If conventional touch panel display devices are used for power and time settings, then the device provides basic operation functionality, but the operation becomes complex and requires multiple steps
Solution Approach 1:
The patent combines power setting and time setting into a single integrated operation. By displaying power and time values on an orthogonal coordinate system and accepting simultaneous input through one touch operation, the device merges two separate setting operations into one unified action, directly reducing operation complexity
Solution Approach 2:
The patent introduces a spatial dimension to the setting operation by using an orthogonal coordinate system where power and time are represented as coordinates. This dimensional transformation allows users to set both parameters by positioning a single point in 2D space rather than performing sequential selections, simplifying the interaction model
2Productivity
If conventional sequential setting operations are used, then each parameter can be set individually, but the number of operations increases and user efficiency decreases
Solution Approach 1:
The patent merges power setting and time setting into a single simultaneous input operation. The touch panel accepts both parameters at once through one coordinate positioning action, eliminating the sequential steps required in conventional devices and directly improving setting efficiency
Solution Approach 2:
The system prepares the orthogonal coordinate system display in advance, showing both power and time values ready for simultaneous selection. This preliminary arrangement of the interface allows users to directly input both parameters in one operation without navigating through multiple screens or menus, reducing the time required for settings

AI summary
An operation device is provided with a GUI display unit (304) which displays a power setting value for defining an operation power of a household appliance, and a time setting value for defining an operation time of the household appliance on an orthogonal coordinate system; and a touch operation unit (301) which simultaneously accepts an input of the power setting value and an input of the time setting value to be displayed on the GUI display unit (304) by an operation of letting a predetermined object touch the GUI display unit (304).
