Solution Overview

Problem

Existing wiping devices face challenges in securely attaching wiping textiles of varying widths due to limited fastening clamp width and reliability issues, leading to restricted compatibility and potential detachment during use, especially with wet textiles.

Innovation Solution

The design incorporates pivotable fastening clamps on the transverse sides of the support body, allowing for wider fastening tabs and improved durability, with adjustable opening angles and latching stations for secure attachment and easy handling, accommodating a variety of textile widths and materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fastening clamp width is increased to accommodate wider wiping textiles, then the versatility and compatibility with different textile widths is improved, but the device complexity increases

Engineering Contradiction:
Improvecompatibility with different textile widthsVSAvoidfastening clamp structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening clamp is designed to be pivotable about a joint, allowing it to dynamically adjust its position and accommodate wiping textiles of varying widths. The clamp can pivot between an open position for insertion and a closed position for secure fastening, providing adaptability without requiring multiple fixed-width clamps.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The single pivotable fastening clamp serves multiple functions: it can fasten wiping textiles of different widths, provide secure retention during use, and allow easy release when needed. This multi-functional design replaces what would otherwise require multiple specialized clamps for different textile widths.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the fastening clamp is made wider to secure broader textiles, then the reliability of attachment is improved, but the ease of operation deteriorates due to reduced accessibility

Engineering Contradiction:
Improveattachment securityVSAvoidclamp accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pivotable design allows the clamp to open wide for easy insertion of the fastening tab, then close securely for reliable attachment. The dynamic movement provides both accessibility during operation and security during fastening, resolving the contradiction between clamp width and operability.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a simple wiping cloth is used without additional attachment devices, then the ease of manufacture is improved, but the reliability of attachment deteriorates

Engineering Contradiction:
Improvewiping cloth simplicityVSAvoidattachment durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

A fastening tab is introduced as an intermediary element between the wiping cloth and the fastening clamp. This simple attachment device provides a dedicated interface for secure fastening without complicating the main wiping cloth structure, maintaining ease of manufacture while improving attachment reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the wiping textile is guided around the front longitudinal side of the supporting body, then the ease of operation is improved, but the reliability of attachment deteriorates due to potential detachment

Engineering Contradiction:
Improvewiping maneuverabilityVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The fastening function is extracted from the main body of the supporting device and implemented as a separate, dedicated fastening clamp mechanism. This specialized component provides reliable attachment specifically for the wiping textile, while the main body remains simple and easy to operate.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The device has a rectangular-shaped support (1) having a longitudinal axis (71) and two longitudinal sides and a transverse axis (72) and two transverse sides (4,5) to which a wiper textile (6) is fixed. A pivotal mounting clamp (7,8) is mounted around a hinge (11,12) for securing a corresponding transverse sides. The fastening tab (13,14) is arranged in the wiper textile. The pivotal mounting clamp in a pivot plane (73,74) which is located perpendicular to the longitudinal axis of the rectangular-shaped support is movable.
