Hand-Held Mop Grip Locking Structure Against Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held mops with soft mounting parts and hard grips tend to disconnect during cleaning operations due to the materials' differing rigidity, interfering with the cleaning process.
Innovation Solution
A hand-held mop design featuring a soft mounting part with a side projection that engages a spring region in the grip, preventing detachment by using a leaf spring member and specific geometric configurations to ensure secure connection between the soft and hard components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mounting part is made of soft material to enable bending during cleaning operation, then the ease of operation is improved, but the reliability of connection between mounting part and grip deteriorates
Solution Approach 1:
The grip is designed with localized elastic regions (spring regions) at specific positions where it contacts the mounting part, while other portions maintain high hardness for secure holding. This local differentiation allows the grip to provide both flexibility for reliable connection and hardness for secure user holding.
Solution Approach 2:
The grip incorporates elastic spring regions that can dynamically deform during insertion and operation, allowing the hard grip material to temporarily flex and then return to its original shape, thereby securing the mounting part through elastic retention force.
2Ease of operation
If the grip is made of hard material to be securely held by the user, then the ease of operation is improved, but the reliability of connection between grip and mounting part deteriorates
Solution Approach 1:
The grip is designed with localized elastic regions (spring regions) at specific positions where it contacts the mounting part, while other portions maintain high hardness for secure holding. This local differentiation allows the grip to provide both flexibility for reliable connection and hardness for secure user holding.
Solution Approach 2:
The grip is constructed as a composite structure combining hard synthetic resin material with localized elastic spring regions, integrating two contrasting material properties (hardness and elasticity) into a single component to simultaneously achieve secure user holding and reliable connection.
3Ease of operation
If the mounting part and grip are connected with different material hardness, then the ease of operation is improved, but the reliability of connection deteriorates due to easy disconnection
Solution Approach 1:
The grip is designed with localized elastic regions (spring regions) at specific positions where it contacts the mounting part, while other portions maintain high hardness for secure holding. This local differentiation allows the grip to provide both flexibility for reliable connection and hardness for secure user holding.
Solution Approach 2:
The grip incorporates elastic spring regions that can dynamically deform during insertion and operation, allowing the hard grip material to temporarily flex and then return to its original shape, thereby securing the mounting part through elastic retention force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents the grip from detaching from the mounting part during cleaning, ensuring a secure and stable operation even when applying force, thus maintaining the mop's functionality and ease of use.
Implementation Method 1
a spring region is formed in the holding side of the grip, and when the insert is inserted into the insert space, the spring region is pressed by the side projection of the insert and bent

AI summary
It is an object of the invention to provide a hand-held mop in which a grip connected to a mounting part for mounting and supporting a mop body is prevented from being detached from the mounting part during cleaning operation. A hand-held mop 1 includes a mop body 2, a mounting part 10, and a grip 20. The mop body 2 has a pair of mop body portions 2a, and the mounting part 10 has a pair of mounting pieces 11 which are inserted into mounting spaces of the mop body portions 2a, and an insert 15. The grip 20 has a holding side 22 which defines an insert space 22a into which the insert 15 of the mounting part 10 is inserted. Further, a side opening 23 is formed in the holding side 22 of the grip 20, and a side projection 19 is formed on the insert 15 of the mounting part 10 and engaged in the side opening 23. A spring region 24 is formed in the holding side 22 of the grip 20, and when the insert 15 is inserted into the insert space 22a, the spring region 24 is pressed by the side projection 19 of the insert 15 and bent.
