Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wringing devices for flat brooms require complex structures and precise user manipulation to stabilize and insert the mop head, making them difficult to use and manufacture.
Innovation Solution
A wringing device with a perforated wall and tabs extending along the longitudinal axis to guide and stabilize the mop head, allowing easy insertion and preventing rotation, featuring a simpler design that centers the mop head during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If guide rails and grooves are added to stabilize the mop head, then stability is improved, but device complexity increases
Solution Approach 1:
The stabilization function is segmented into two simple opposing tabs that only need to prevent rotation in one direction, rather than using complex guide rails and grooves. Each tab independently provides stabilization, simplifying the overall structure while maintaining effectiveness.
Solution Approach 2:
The invention extracts only the essential stabilization function from the complex guide rail and groove system. By removing unnecessary structural elements and keeping only the critical rotation-preventing tabs, the design achieves stability with minimal complexity.
2Measurement precision
If complex manipulation is required to align guide rails with grooves, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The tabs are positioned and oriented to automatically guide the mop head into the correct position during insertion. The structure itself performs the alignment function without requiring the user to manually manipulate or align components, making the operation intuitive and effortless.
Solution Approach 2:
The tabs are pre-positioned on the wringing basket to create an automatic guiding path. This preliminary structural arrangement ensures that as the user inserts the mop head, the alignment is achieved automatically through the physical constraints provided by the tabs, eliminating the need for complex user manipulation.
3Ease of manufacture
If symmetric tabs are used for guidance, then ease of manufacture is improved, but adaptability to different insertion angles deteriorates
Solution Approach 1:
The tabs are designed with asymmetric positioning and orientation relative to the wringing basket's rotation axis. This asymmetric configuration creates a specific geometric relationship that guides the mop head into the correct alignment during insertion, while still maintaining manufacturing simplicity through the basic tab structure.

AI summary
The invention relates to a wringing device (1) comprising: - a wringer basket, - a support for the basket, - a guide device for guiding the basket in rotation relative to the support about a longitudinal axis, the guide device being assembled to the support and to the basket, characterised in that it comprises two tabs (32, 34) opposite each other assembled to the wringer basket and extending along the longitudinal axis from the cavity of the basket to beyond the main opening outside the basket, the tabs being spaced apart from each other in such a way as to: - guide the insertion of two side plates of a mop head between the two tabs when these plates are parallel to the longitudinal axis, - prevent the plates from being rotated about the main axis in at least one direction of rotation relative to the basket when these plates are inserted into the cavity of the basket.
