Refrigerator Dispenser Menu Control With Dynamic Button Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator control units are cumbersome due to the complexity of menus and buttons, which makes it difficult for users to easily select and display various functions and settings, and the simultaneous display of upper and lower menus causes user inconvenience.
Innovation Solution
A control unit with an input means for receiving operation signals, a storage means for mode image data, and a display means that allows for sequential display of mode images and information, simplifying the input unit configuration and enabling more intuitive menu selection through a limited number of buttons, with the ability to display mode images, information images, and background images in an overlapping manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are provided for each menu and manipulation function, then all menu functions can be controlled, but the input unit becomes complicated
Solution Approach 1:
The patent applies multi-functionality by enabling buttons to perform different operations based on the current display state. The same button can serve as a selection button when menus are displayed and as a value adjustment button when menu details are displayed, eliminating the need for separate dedicated buttons for each function.
Solution Approach 2:
The patent implements dynamic button functionality where the operation of each button changes according to the current display mode. The control unit dynamically assigns different functions to buttons based on whether the display shows menu lists, menu details, or other information, allowing the interface to adapt to different user interaction contexts.
2Loss of information
If upper menus and lower menus are simultaneously displayed, then all menu information is visible, but user identification and selection becomes difficult
Solution Approach 1:
The patent segments menu display into hierarchical levels (upper menus and lower menus) that are displayed sequentially rather than simultaneously. The display unit shows one menu level at a time, allowing users to focus on the current selection context without being overwhelmed by multiple nested menu levels displayed at once.
Solution Approach 2:
The patent implements periodic display switching between different menu levels. When a user selects a menu item, the display periodically transitions from showing the parent menu to showing the child menu details, and can return to the parent menu level, creating a rhythmic interaction pattern that improves user orientation.
