Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines lack an efficient mechanism for automatically adjusting contact pressure on different floor types, leading to suboptimal cleaning results when transitioning between carpets and smooth floors.
Innovation Solution
A floor cleaning machine design featuring a lever system with pivot bearings that automatically adjusts the contact pressure of the sweeping roller based on the floor type, using a traction mechanism with a load section and deflection element to respond to torque changes, allowing for optimized cleaning across various surfaces without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of contact pressure is used, then operator control is maintained, but cleaning efficiency decreases due to continuous intervention
Solution Approach 1:
The system automatically adjusts contact pressure through the lever mechanism that responds to torque changes from the motor device, eliminating the need for continuous manual adjustment and enabling self-regulating operation across different floor types
Solution Approach 2:
The lever mechanism provides automatic feedback control by detecting torque changes in the traction element and adjusting the contact pressure accordingly, creating a closed-loop system that maintains optimal cleaning performance without operator intervention
2Adaptability or versatility
If fixed contact pressure is used, then device structure is simple, but cleaning performance deteriorates on different floor types
Solution Approach 1:
The contact pressure is made dynamically adjustable through the lever mechanism that automatically changes position in response to motor torque, allowing the system to adapt to different floor types without complex manual adjustment systems
Solution Approach 2:
The lever acts as an intermediary mechanism between the motor device and the sweeping roller, translating torque changes into contact pressure adjustments and enabling automatic adaptation without direct operator control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures effective cleaning by automatically adjusting contact pressure and position of the sweeping roller, maintaining optimal cleaning performance across different floor types, including carpets and smooth floors, without operator intervention.
Implementation Method 1
a lever (96) which is pivotably arranged at the base (12) on a second pivot bearing (98) about a second pivot axis (100)
Implementation Method 2
The motor unit (72) exerts a corresponding tensile force via the load section (88) to drive the rotation of the sweeping roller (64). The action of the sweeping roller (64) on the floor to be cleaned generates a counter-torque
Implementation Method 3
a traction device with a traction element for transmitting torque from the motor device to the sweeping roller
