Operation Status Display for Air Conditioners Using Past-Present-Future LEDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners fail to notify users promptly of the need for setting changes in heat pump type air-conditioning and hot water supply systems, leading to inefficiencies in energy saving and comfort management due to complex operational procedures and unfamiliarity with setting methods.
Innovation Solution
An operation state display device that acquires and displays past, present, and future operation states using lighted LEDs and a touch display, allowing users to easily identify necessary setting changes through intuitive screen transitions and historical data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional air conditioners display only present operation state or abnormal state, then the display function is simple, but users cannot notice the situation requiring setting change at early stage
Solution Approach 1:
The display system is segmented into three distinct LED indicators representing past, present, and future operation states. Each LED can be independently controlled to show different colors corresponding to different operation modes, allowing users to view temporal operation information without complicating the overall display structure
Solution Approach 2:
The patent adds a temporal dimension to the display by showing past, present, and future operation states simultaneously through separate LEDs. This transforms the conventional single-state display into a multi-temporal display system, enabling users to notice setting change needs at early stage by comparing future planned operations with current settings
2Ease of operation
If conventional air conditioners require confirming information through multiple screens of past operation history and future operation plan, then comprehensive information is provided, but too many operational procedures prevent quick setting change
Solution Approach 1:
The patent extracts the essential future operation plan information and presents it directly through the future operation state LED indicator, eliminating the need for users to navigate through multiple screens of detailed operation history and plans. This extraction of key information allows quick setting change while still providing comprehensive temporal context
Solution Approach 2:
The system performs preliminary display of future operation states through dedicated LEDs before users need to make setting changes. By showing the future operation plan in advance through simplified visual indicators, users can proactively adjust settings without undergoing complex multi-screen confirmation procedures

AI summary
In an operation state display device 10, a past operation state display portion 11 is lighted in a lighting color indicating a past operation state in an air conditioning and hot water supply system, a present operation state display portion 12 is lighted in the lighting color indicating a present operation state, and a future operation state display portion 13 is lighted in the lighting color indicating a future operation state. A screen display portion 17 displays an operation history display screen in pressing of a past input operation portion 14, a present setting content display screen in pressing of a present input operation portion 15, and an operation plan display screen in pressing of a future input operation portion 16.
