Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary product handles require screw connections, which are difficult to install and disassemble, especially in confined spaces, and are prone to rust and corrosion, making maintenance and replacement inconvenient.
Innovation Solution
A handle connecting structure that uses a connecting shaft sleeve and sliding clamping plate with an elastic member, allowing for screwless assembly and disassembly through a clamping groove mechanism, facilitated by a guiding protrusion and elastic member interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connection is used to fix the handle, then the connection strength is improved, but the ease of operation deteriorates due to difficulty in installation and disassembly in confined spaces
Solution Approach 1:
The connection structure is divided into separate components: a handle body with connecting shaft sleeve and a base with connecting sleeve. The sliding clamping plate can move independently within the connecting sleeve, allowing the connection to be segmented into assembly and disassembly phases without requiring tool intervention.
Solution Approach 2:
The sliding clamping plate is designed to be movable within the connecting sleeve rather than fixed. This dynamic element can slide radially to transition between clamped and released states, enabling quick assembly by simple insertion and easy disassembly by pushing the clamping plate, eliminating the need for screwdrivers in confined spaces.
2Reliability
If screw connection is used to fix the handle, then the connection reliability is improved, but the ease of repair deteriorates due to rust and corrosion in humid environments
Solution Approach 1:
The screw connection is completely extracted from the design. Instead of using threaded fasteners that are prone to rust and corrosion, the patent employs a purely mechanical interference fit with a sliding clamping plate that can be released by simple radial movement, eliminating the repair difficulties associated with corroded screws in humid sanitary environments.
Solution Approach 2:
The elastic member provides self-contained clamping force without requiring external fasteners. The system is designed to maintain its own connection through the elastic deformation of the clamping plate, which can be easily released by applying force to move the clamping plate radially, allowing quick replacement without complex disassembly procedures.
3Ease of operation
If sliding clamping plate with elastic member is used instead of screw connection, then the ease of operation is improved for quick assembly and disassembly, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into the sliding clamping plate: it serves as both the clamping element and the disassembly mechanism. The same component that provides the connection force through elastic deformation also serves as the release mechanism when pushed radially, eliminating the need for separate fasteners and tools, thereby reducing overall device complexity despite the added elastic member.

AI summary
The present application discloses a handle connecting structure. The handle connecting structure comprises a handle body having a connecting shaft sleeve, a connecting base having a connecting sleeve, and a sliding clamping plate assembled in the connecting sleeve and capable of sliding along a radial direction of the connecting sleeve. The connecting shaft sleeve can be pluggably inserted into the connecting sleeve. A clamping groove can be provided on a circumferential surface of the connecting sleeve. The sliding clamping plate may comprise a clamping main plate with a clamping plate through hole, a guiding protrusion, and an elastic member connected to opposite sides of the clamping main plate. The connecting shaft sleeve can be inserted into the connecting sleeve and passes through the clamping plate through hole. The clamping main plate can be clamped in the clamping groove.
