Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user selects a menu from the main screen and then selects a specific button on the detailed menu, then the user can access specific functions, but the operation becomes complex and inconvenient requiring multiple selections
Solution Approach 1:
The system performs preliminary action by automatically displaying the function management screen corresponding to the opened door compartment before the user needs to access it. When the door opening/closing detection unit detects that a door is opened, the control unit proactively displays the relevant function management screen on the display unit, eliminating the need for users to navigate through multiple menu selections to reach the desired function screen.
2Productivity
If the system displays the main screen with various menu options, then users have access to all functions, but users must sequentially select multiple options to reach the desired screen
Solution Approach 1:
The control unit performs preliminary action by automatically displaying the appropriate function management screen based on which door compartment is opened, rather than requiring users to navigate through the main screen and multiple sub-menus. This preliminary display action significantly reduces the time users spend navigating menus to access frequently used functions related to the opened compartment.
3Adaptability or versatility
If the system requires users to select menus from the main screen, then all functions are accessible, but the operation process becomes lengthy and inconvenient
Solution Approach 1:
The control unit automatically adapts the display content based on which door compartment is opened, performing preliminary action to show the most relevant function management screen. This maintains the versatility of having all functions accessible while dramatically improving ease of operation by eliminating the need for users to manually navigate through the main screen and multiple selection layers to reach commonly used functions.

AI summary
A home appliance includes a main body having a storage compartment, a door that opens or closes the storage compartment, a detection unit to detect an opening or closing of the door, a display unit disposed on the main body or the door to display information, and a control unit to control the display unit on the basis of the detection by the detection unit. The control unit changes a display on the display unit from a main screen to a function management screen in response to a command inputted on the main screen when the main screen is displayed on the display unit, and the control unit changes a display on the display unit from the main screen to the function management screen in response to the opening or closing of the door detected by the detection unit when the main screen is displayed on the display unit.
