Floor processing device with a battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floor processing devices, such as cleaning robots, often require recharging during operations due to insufficient battery energy, which delays task completion and reduces battery lifespan, as they must stop to recharge and may need frequent recharging.
Innovation Solution
The control device calculates the anticipated energy required for a task and adjusts operating parameters, like motor speed or cleaning mode, to reduce energy consumption, allowing tasks to be completed with available battery charge without immediate recharging, and can interrupt tasks to charge during resting phases if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is recharged immediately when energy is insufficient, then the battery charge level is maintained, but the operating activity must be interrupted and time is lost
Solution Approach 1:
The control device dynamically adjusts operating parameters (speed, power consumption) in real-time based on battery charge level and task progress, enabling continuous operation without interruption by adapting the system behavior to current energy availability
Solution Approach 2:
The system changes operational parameters such as motor speed and power consumption levels to match available battery energy, allowing the operating activity to continue uninterrupted by operating within energy constraints rather than stopping to recharge
2Reliability
If the battery is recharged frequently to maintain sufficient energy, then the battery charge level is maintained, but the service life of the battery is reduced
Solution Approach 1:
The control device modifies operating parameters to reduce power consumption and extend battery usage duration, allowing complete task execution on a single charge cycle and thereby reducing the frequency of recharging and extending battery service life
Solution Approach 2:
The control device calculates anticipated energy requirements before executing the operating activity and adjusts parameters in advance to ensure sufficient energy for complete task completion, preventing the need for frequent recharging cycles that would reduce battery lifespan
3Use of energy by moving object
If the operating parameters are adjusted to reduce energy consumption, then the energy required is reduced, but the performance of the operating activity may be compromised
Solution Approach 1:
The system dynamically adapts operating parameters based on real-time conditions and battery status, optimizing the balance between energy consumption and task performance by adjusting speed and power levels according to current energy availability and task requirements
Solution Approach 2:
The control device modifies operational parameters within an optimized range that maintains acceptable task performance while reducing energy consumption to match available battery capacity, achieving a balanced solution rather than extreme parameter reduction

AI summary
A floor processing device has at least one electrical consumer, a battery for supplying power to the electrical consumer, and a control device for controlling the floor processing device. In order to avoid recharging the battery during an operating activity, the control device determines the anticipated energy required by one or more consumers to perform and fully complete a predefined operating activity, compares the anticipated energy required with an amount of energy stored in the battery, and if the stored amount of energy is less than the energy required, reduces the energy required by adjusting one or several operating parameters for the operating activity, in order to successfully execute the operating activity.
