Solution Overview
Problem
Current home energy management systems lack effective user interfaces and automated control mechanisms to efficiently monitor and reduce energy consumption, particularly in residential settings, and do not facilitate comparison with neighbor's energy usage for competitive savings.
Innovation Solution
A consumer electronics device with a processor and video display that presents a user interface showing energy usage by room, allows users to define energy-saving rules, and compares energy consumption with neighbors, enabling automated control of appliances and tailored energy-efficient appliance advertisements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of energy-using devices is used, then users can directly control individual devices, but users must repeatedly operate devices manually which is inconvenient
Solution Approach 1:
The system performs preliminary actions by automatically controlling energy-using devices based on pre-set conditions and user preferences. The microprocessor monitors sensor data and automatically adjusts devices without requiring manual user intervention, thus resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The energy management system provides self-service functionality where the microprocessor and sensors automatically monitor conditions and control devices based on programmed rules. The system serves itself by making autonomous decisions about device operation, eliminating the need for repeated manual user operations.
2Ease of operation
If automated local control is implemented, then repeating manual operation is avoided, but the system requires complex automation mechanisms
Solution Approach 1:
The automated control system is segmented into independent functional modules: sensors for monitoring environmental conditions, a microprocessor for logical decision-making, and actuators for device control. Each module performs a specific function, which simplifies the overall system design and maintenance while providing comprehensive automation capability.
Solution Approach 2:
The microprocessor-based control system serves multiple functions: it monitors sensor data, processes logical conditions, controls various energy-using devices, and provides user interface operations. This multi-functional approach consolidates what could be multiple separate systems into a single versatile controller, reducing overall system complexity.
3Ease of operation
If remote control via service provider is used, then devices can be controlled remotely, but customer privacy and control autonomy are reduced
Solution Approach 1:
The system provides dynamic control where the level of automation and remote intervention can be adjusted based on customer preferences. Users can program different levels of autonomy for different devices or time periods, allowing the system to adapt between fully automatic operation and manual control modes, thus maintaining customer autonomy while providing remote control capability when desired.
4Loss of information
If detailed energy monitoring is implemented, then users can see energy consumption data, but the user interface becomes complex and difficult to navigate
Solution Approach 1:
The user interface segments energy consumption information by functional categories such as rooms, device types, or time periods. This organization allows users to access detailed energy data in a structured, easy-to-navigate format rather than presenting all data at once, thus maintaining information availability while improving interface simplicity.
Solution Approach 2:
The system presents energy consumption data across multiple dimensions including temporal (historical vs. current), spatial (different rooms or devices), and categorical (different device types) perspectives. This multi-dimensional presentation allows users to understand energy consumption patterns without overwhelming the interface with raw data.

AI summary
A CE device employs user interfaces to allow a user to define energy management rules within the user's premises, visualize energy use in the home and in neighbor's homes for comparison and competition in saving energy, and receive tailored advertisements for appliances that are more energy efficient than what the user currently owns.
