Cleaning Energy Storage Buffer for Peak Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices consume high maximum electrical power, leading to increased installation and contractual costs, as well as environmental concerns, despite some energy-saving concepts, which still result in significant power consumption when all loads are activated simultaneously.
Innovation Solution
A cleaning device with an energy store that temporarily stores electrical energy received via an electrical connection and supplies it to electrical loads, allowing for selective switching between energy store and direct electrical connection supply, optimizing power usage by varying the energy ratio based on operating states and reducing peak power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all electrical loads are activated simultaneously to meet cleaning requirements, then cleaning performance is improved, but maximum electrical power consumption increases
Solution Approach 1:
The energy store is charged in advance during periods of low power demand (standby mode, night hours, or when cleaning chamber is empty) so that electrical energy is available when all loads need to operate simultaneously during cleaning operations, eliminating the need to increase maximum power consumption from the electrical connection
Solution Approach 2:
The energy store acts as an intermediary between the electrical connection and the electrical loads, decoupling the instantaneous power demand from the maximum power supply requirement. It absorbs excess energy when demand is low and releases it when demand peaks, allowing full load operation without increasing maximum electrical power consumption
2Power
If maximum electrical power is increased to supply all loads simultaneously, then power availability to loads is improved, but installation costs and contractual costs increase
Solution Approach 1:
By charging the energy store in advance during low-demand periods, the system ensures sufficient power is stored to meet peak demands without requiring expensive upgrades to electrical infrastructure or increased contractual power agreements
Solution Approach 2:
The energy store serves as a buffer that allows the cleaning device to operate with a lower-rated electrical connection than would otherwise be required, directly reducing installation costs for electrical infrastructure and contractual costs for power supply agreements
3Power
If energy is stored temporarily to reduce peak power consumption, then maximum electrical power consumption is reduced, but device complexity increases
Solution Approach 1:
The energy store is integrated into the existing electrical system architecture as a straightforward energy buffer component, connected between the electrical connection and the loads. This modular integration adds minimal complexity while achieving significant peak power reduction
Solution Approach 2:
The controller automatically manages the charging and discharging of the energy store based on operational state, power availability, and load requirements, eliminating the need for complex external control systems or user intervention
