Solution Overview

Problem

Existing wiper plates require a large section of the mop cover to be wrapped around the edge to reach clamping areas, resulting in a significant portion of the mop cover being unused, and moving clamping areas closer to the edge is not feasible due to design constraints.

Innovation Solution

The peripheral edge of the wiper plate is formed perpendicular to the cleaning surface, allowing the clamping area with penetration to be directly adjacent to the edge, with angled clamping elements forming a receiving space that minimizes the mop cover section needed to be wrapped around the plate, and incorporating an elastic insert with slits to create flexible clamping elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If clamping areas are positioned far from the edge of the wiper plate, then the cleaning surface area is increased, but a large section of the mop cover remains unused

Engineering Contradiction:
Improvecleaning surface areaVSAvoidunused mop cover section
Core Design Contradiction:
Area of stationary objectVSLoss of substance

Solution Approach 1:

The clamping area is positioned in the peripheral edge region of the wiper plate, utilizing the vertical dimension and edge geometry rather than horizontal distance from the cleaning surface. This allows the clamping area to be adjacent to the edge while maintaining sufficient cleaning surface area, as the clamping structure uses the edge profile rather than horizontal space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of substance

If clamping areas are moved closer to the edge of the wiper plate, then the mop cover utilization is improved, but space for forming a suitable penetration surrounded by clamping elements is reduced

Engineering Contradiction:
Improveunused mop cover sectionVSAvoidspace for penetration and clamping elements
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The peripheral edge region of the wiper plate is given a different local quality with increased material thickness compared to the main body. This localized structural enhancement provides sufficient space for the penetration and clamping elements exactly where needed at the edge, without affecting the overall compactness or requiring additional horizontal space.

Inventive Principle:
Principle #3Local quality

3Loss of substance

If the peripheral edge is formed perpendicular to the cleaning surface, then the clamping area can be directly adjacent to the edge, but the structural integrity of the cleaning pad holder may be compromised

Engineering Contradiction:
Improveunused mop cover sectionVSAvoidcleaning pad holder structural integrity
Core Design Contradiction:
Loss of substanceVSStrength

Solution Approach 1:

The wiper plate is constructed as a composite structure with a peripheral edge region having different material properties (increased thickness) compared to the main body. This composite design allows the perpendicular edge formation for clamping while maintaining structural integrity through the reinforced edge zone that can support the cleaning pad holder.

Inventive Principle:
Principle #40Composite materials

AI summary

The wiper plate (1) has a peripheral edge portion (5), where a wiper plate bottom is provided for forming a clamping region (2), which is covered when used as directed by a mop. The clamping region forms an inner receiving space, where an inward-facing surface of a wiper base plate is placed at a specific angle.
