Solution Overview
Problem
Traditional floor treatment machines with components on the driving shaft are maneuverable but cause significant operator fatigue due to the weight, limiting their flexibility and productivity in cleaning and drying performance.
Innovation Solution
Incorporation of elastic means, such as coil springs, to reduce the effort required to rotate the driving shaft by providing elastic resistance and thrust, allowing for adjustable pressure on components like brushes and wipers, and enhancing the machine's maneuverability and cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are arranged along the driving shaft to improve maneuverability, then the machine becomes more maneuverable in limited spaces, but the weight of the shaft increases causing operator fatigue
Solution Approach 1:
The patent introduces a rotational degree of freedom to the driving shaft, allowing it to rotate about its longitudinal axis. This dynamic capability enables the shaft to adapt its orientation during operation, improving maneuverability in tight spaces without requiring increased shaft weight or additional heavy components.
Solution Approach 2:
The driving shaft is divided into multiple sections that can rotate relative to each other. This segmentation allows different parts of the shaft to be positioned independently, enhancing maneuverability in confined spaces while distributing the weight burden across multiple lighter segments rather than a single heavy continuous shaft.
2Productivity
If the shaft weight is increased to apply more pressure on brushes and wipers, then cleaning and drying performance improves, but operator fatigue increases
Solution Approach 1:
The rotational capability of the driving shaft allows the operator to dynamically adjust the contact pressure between brushes/wipers and the treated surface by rotating the shaft to different angular positions. This enables optimal cleaning performance without requiring excessive shaft weight, as the pressure can be modulated through rotation rather than solely through weight.
Solution Approach 2:
The patent changes the operational parameters of the cleaning system by introducing rotational movement. Instead of relying on static weight for pressure, the system uses rotational position as a variable parameter to control contact force, allowing flexible adjustment of cleaning intensity without increasing shaft mass.
3Weight of moving object
If the shaft is made rigid and devoid of components to reduce weight, then operator fatigue decreases, but the machine becomes bulky and poorly maneuverable
Solution Approach 1:
Rather than making the shaft rigid and component-free, the patent introduces controlled rotational dynamics. The shaft remains relatively lightweight but gains maneuverability through its ability to rotate about its longitudinal axis, allowing it to navigate tight spaces and adjust to different operational requirements without becoming bulky.
Solution Approach 2:
The driving shaft is designed to perform multiple functions: it transmits power, supports components, and rotates to provide maneuverability. This multi-functionality eliminates the need for separate heavy structural elements, maintaining low weight while achieving excellent maneuverability through the rotational capability.

Function Achieved in This Case
The solution reduces operator fatigue, increases cleaning performance, and enhances the machine's flexibility and productivity by mitigating the weight-related issues of the driving shaft, enabling more efficient treatment of treadable surfaces.
Implementation Method 1
elastic contrast means, and the rotation of said driving element in a first rotation direction results in the engagement of said elastic means by said driving element and in an elastic resistance exerted by said elastic means against the rotation of said driving element in said first rotation direction, and where the rotation of said driving element in a second rotation direction opposite to said first rotation direction is promoted by the elastic thrust exerted by said elastic means against said driving element
