Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet brushes are difficult to thoroughly clean, prone to damage, and have compatibility issues with different head and handle brands, leading to loose clamping, water ingress, and blockages, causing inconvenience and hygiene problems.
Innovation Solution
A toilet cleaner design featuring a handle with a housing, clamping jaw, and spring mechanism that securely clamps heads of varying thicknesses and brands, with a seal groove and surfactant-impregnated brush sheets for improved stability and cleaning efficiency, preventing water ingress and facilitating easy head replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible jaw is limited by an opening corresponding to housing members and an angle between two clamping jaws is forced to be reduced, then the clamping ability is improved, but the housing members are apt to be broken due to high requirements for shapes of the clamped part
Solution Approach 1:
The clamping jaw is designed to be rotatable relative to the housing members, transforming a static rigid structure into a dynamic adjustable one. This allows the clamping angle to be adjusted according to the thickness and shape of the head, reducing stress concentration on the housing members and preventing breakage while maintaining effective clamping ability.
2Manufacturing precision
If the part to be clamped needs to match with the handle in thickness, then the clamping precision is improved, but the compatibility between head and handle of different brands is reduced
Solution Approach 1:
The handle is designed with a universal clamping mechanism that can accommodate heads of different thicknesses and shapes through adjustable clamping jaws. The rotatable clamping jaw and adjustable opening allow the same handle to work with heads from different brands, achieving both precision clamping and broad compatibility.
3Productivity
If the head is soaked in water, then the cleaning ability is improved, but the head becomes loose and is easily detached from the handle
Solution Approach 1:
The clamping jaw is designed to be rotatable and adjustable, allowing the user to tighten the clamping force after the head is soaked. The dynamic adjustment capability compensates for the loosening effect of water soaking, maintaining secure attachment even when the head is wet and flexible.
4Ease of operation
If the handle is tilted or inverted, then the usability is improved, but dirty water will infuse, seep and flow into the hand-held part of the handle
Solution Approach 1:
A waterproof seal structure is designed at the interface between the clamping jaw and the housing members to prevent dirty water from entering the handle interior. This preliminary protective measure counteracts the harmful effect of water ingress when the handle is tilted or inverted, keeping the hand-held part clean and dry.

AI summary
A toilet cleaner, including a head and a handle for clamping the head. The handle includes a housing, a manipulation component, and a clamping jaw. A clamping end of the housing is provided with a first clamping head and is hinged to a middle portion of the clamping jaw. The manipulation component is fitted in the housing and includes a handling portion at a grip end of the housing. An outer end of the clamping jaw has a second clamping head corresponding to the first clamping head, and the manipulation component is connected to an inner end of the clamping jaw, so that the first clamping head and the second clamping head are matched with each other. The present invention is more firm and reliable with better compatibility, so that the handle can conveniently and reliably clamp the heads in different thicknesses, or of various brands, forms or specifications.
