Solution Overview

Problem

Existing cleaning device frames are not adaptable to mops of different shapes and sizes, requiring separate frames for each type, which increases production costs and complexity.

Innovation Solution

A modular frame system comprising five components: three carrier plates of different lengths and one width, and two clamping elements, allowing for the production of four different frames that can accommodate mops of varying shapes and sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate frames are produced for each mop type, then each frame is optimized for its specific mop, but production costs and complexity increase

Engineering Contradiction:
Improveframe adaptability to different mop typesVSAvoidframe system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame is designed with a universal structure that can accommodate multiple mop types through adjustable components. The carrier plate and clamping mechanism can be configured to fit different mop dimensions and shapes, allowing a single frame design to serve multiple functions rather than requiring separate dedicated frames for each mop type.

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

Solution Approach 2:

The frame is divided into modular components including the carrier plate, clamping elements, and adjustable segments. This segmentation allows individual components to be adjusted or reconfigured to accommodate different mop types, reducing the need for completely different frame designs while maintaining optimal fit for each application.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If separate frames are produced for each mop type, then each frame fits its specific mop perfectly, but production costs increase

Engineering Contradiction:
Improveframe adaptability to different mop sizesVSAvoidframe production cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By designing a universal frame with adjustable features, the same base components can be used across multiple mop types, significantly reducing production costs through economies of scale in manufacturing common parts while still achieving proper fit for different mop sizes through adjustment mechanisms.

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

Solution Approach 2:

The frame incorporates adjustable parameters such as variable clamping positions, adjustable carrier plate configurations, and modifiable segment lengths. These parameter changes allow a single frame design to adapt to different mop dimensions without requiring multiple production variants, thereby reducing manufacturing costs while maintaining versatility.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If multiple frame types are maintained, then each frame is optimized for its specific use, but assembly errors increase

Engineering Contradiction:
Improveframe-mop fit accuracyVSAvoidframe assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The modular segmented design with standardized connection interfaces and clear assembly features guides users through a systematic assembly process. Each segment has defined mounting positions and connection mechanisms that reduce assembly errors, while the segmentation allows for optimized fit accuracy for different mop types through selective configuration of the modular components.

Inventive Principle:
Principle #1Segmentation

AI summary

A frame system for a modular construction of flat mop cleaning device frames including a first carrier plate having a first length in a longitudinal direction and a first width in a transverse direction, and a second carrier plate having a second length in the longitudinal direction different from the first length and a second width in the transverse direction corresponding to the first width. The frame system includes a third carrier plate having a third length in the longitudinal direction different from the first and second length, and a third width in the transverse direction corresponding to the first and second width. The frame system further includes a first clamp forming longitudinal delimitations of the first, second and third carrier plates and a second clamp forming longitudinal delimitations of the third carrier plate. The second clamp has a greater length than the first clamp.
