Standby Power Supply Using Internal Battery for Appliance Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern appliances, such as kitchen appliances with electronic features, continue to consume excessive external power during standby mode, exceeding industry and government-set power consumption limits, despite efforts to reduce energy usage.
Innovation Solution
A system that utilizes an internal power source, like a battery, to supplement power to electronic components during standby mode, ensuring external power consumption remains within predetermined limits by determining when the appliance is in standby, providing power from the internal source when needed, and replenishing it without exceeding the limits, and disabling features if necessary to maintain compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an appliance operates electronic features during standby mode, then the appliance maintains functionality and user convenience, but the external power consumption exceeds the maximum power consumption limitation
Solution Approach 1:
The power supply system is segmented into multiple sources: an external power source for recharging and an internal power source (battery) for standby operation. This segmentation allows the appliance to draw power from different sources depending on the operational mode, enabling standby functionality while limiting external power consumption to compliant levels.
Solution Approach 2:
An internal power source acts as an intermediary between the external power source and the electronic features. During standby mode, the internal power source mediates by providing power locally, preventing direct power draw from the external source that would exceed consumption limits. The intermediary enables continued functionality while complying with power restrictions.
2Use of energy by moving object
If an internal power source is used to supplement power during standby mode, then external power consumption is limited to compliance levels, but the appliance requires additional components and system complexity
Solution Approach 1:
The internal power source serves multiple functions: it provides power during standby mode to maintain compliance, stores energy for later use, and can operate independently when external power is unavailable. This multi-functionality justifies the added complexity by providing versatile power management capabilities that address both compliance and reliability concerns.
Solution Approach 2:
The system dynamically changes power supply parameters by switching between external and internal power sources based on operational mode. During standby, the system transitions to using the internal power source, changing the power supply configuration to meet consumption limits. This parameter change enables compliance without permanent structural complexity.
3Reliability
If the internal power source is continuously replenished, then the appliance maintains full functionality, but the external power consumption may exceed the predetermined limit
Solution Approach 1:
The replenishment of the internal power source occurs periodically during active operation modes rather than continuously during standby. The system charges the battery when the appliance is in use and external power consumption limits are not applicable, then uses the stored energy during standby periods. This periodic action maintains reliability while avoiding continuous power draw that would exceed limits.
Solution Approach 2:
The internal power source is replenished in advance during active operation modes before standby mode begins. By performing the charging action preliminarily when power limits do not apply, the system ensures the internal source is available for standby without drawing excessive power during the standby period itself, thus maintaining reliability while complying with consumption limits.

Data Source
AI summary
A system is provided for supplementing the power usage of an appliance with an internal power source, such as e.g., a battery, in order to limit the overall power consumption of the appliance while in standby mode. The system can allow for replenishing the internal power source when the appliance is not in standby mode or even when in standby mode if such will not exceed the external power source consumption limit. In the event the internal power source is not available or is reaching depletion, the system can provide for disabling electronic features of the appliance in order to maintain the external power source consumption below the desired limit.
