Toilet Cover Hinge Quick-Release Structure for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet cover hinges are cumbersome to assemble and disassemble, requiring users to hold components steady and bend down to align bolts and nuts, making the process time-consuming and laborious, especially during cleaning.
Innovation Solution
A quick-release structure featuring a fixing bolt with a bolt head, stopper, and neck, a locking base with a locking ring and arched notches, and a lid with a pivot and stopping block, allowing for easy alignment and secure engagement of the toilet cover, enabling quick assembly and disassembly without removing the fixing bolt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bolts and nuts are used to connect the toilet cover and hinge, then the connection is secure, but the assembly and disassembly process becomes time-consuming and laborious
Solution Approach 1:
The hinge is divided into separate components: a locking base that remains attached to the toilet cover, and a lid that can be quickly detached. The fixing bolt is segmented with a removable lid portion that allows tool-free assembly and disassembly while maintaining secure connection when engaged
Solution Approach 2:
The hinge transitions from a static bolt-nut connection to a dynamic quick-release mechanism where the lid can be easily moved between locked and unlocked positions. The sliding trough and stopper enable dynamic adjustment and quick release without tools
2Stability of the object's composition
If the toilet cover is securely fastened with bolts and nuts, then the connection is stable, but disassembly for cleaning becomes difficult and requires bending down
Solution Approach 1:
The lid portion of the fixing bolt is extracted as a separate removable component. Users can easily remove the lid to access and clean the hinge area without disassembling the entire connection or bending down to unscrew nuts
Solution Approach 2:
The stopping block acts as an intermediary that provides finger access to release the locking mechanism. This allows users to easily disengage the hinge components for cleaning while maintaining stable connection during normal use
3Ease of operation
If the engaging board and toilet cover are not fixedly connected, then alignment is difficult and blocks user sight, but fixed connection makes disassembly laborious
Solution Approach 1:
The locking base is pre-attached to the toilet cover with the fixing bolt body, so users only need to attach the lid component. This preliminary action eliminates the need to hold and align multiple components during assembly, simplifying the process while maintaining connection stability

AI summary
A quick-release structure of a toilet cover hinge includes a fixing bolt, a locking base, and a lid. To assemble, the present invention is coupled to a toilet cover. The fixing bolt is inserted into and engaged with a elongated engaging hole, and a stopping block is to press against the bolt head, which locks the toilet seat to the fixing bolt. To disassemble, the user places their fingers into arched notches of the locking base to pull the lid up and to disassemble the toilet cover for replacement or cleaning; the fixing bolt does not need to be unscrewed from the toilet bowl to remove the toilet seat. To reassemble, the locking base directly engages with the fixing bolt, which provides for a quick and convenient assembly and disassembly of the toilet seat.
