Assembly-and-disassembly structure for toilet cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet cover assembly-and-disassembly structures require buttons for operation, which are prone to dirtiness and necessitate multiple steps, compromising ease and hygiene.
Innovation Solution
A novel assembly-and-disassembly structure for a toilet cover that uses a cover plate assembly connected to support bases via rotation shafts with locking rods and torsion springs, allowing for single-step operation without buttons, enhancing safety and stability by requiring simultaneous vertical pressing on both sides for disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are used for assembly-and-disassembly operation, then quick assembly-and-disassembly can be achieved, but the buttons are easily dirtied and require multiple steps
Solution Approach 1:
The patent removes the button component entirely from the system. Instead of using buttons that can be dirtied, the invention employs a buttonless locking mechanism where the cover plate is directly locked to the support base through a locking rod and locking groove structure, eliminating the source of dirtiness while maintaining quick operation
Solution Approach 2:
The locking rod automatically engages with the locking groove through elastic deformation and mechanical interaction. The system self-locks when the cover plate is installed and self-unlocks when vertical force is applied, eliminating the need for manual button operation and reducing steps required for assembly-and-disassembly
2Ease of operation
If buttons are arranged at the end of the cover plate for operation, then assembly-and-disassembly can be performed, but the button location is easily dirtied
Solution Approach 1:
The button component located at the end of the cover plate is completely removed. The locking function is integrated directly into the cover plate structure through the locking rod, eliminating the need for a separate button element that would be susceptible to dirt accumulation at the end position
3Ease of operation
If a button-based locking mechanism is used, then assembly-and-disassembly can be achieved, but it requires two steps to operate
Solution Approach 1:
The patent combines the locking and unlocking functions into a single integrated mechanism. The locking rod serves both functions: it automatically locks when the cover plate is installed and automatically unlocks when vertical force is applied to the cover plate, merging what would traditionally be separate locking and unlocking operations into one unified action
Solution Approach 2:
The system performs both locking and unlocking automatically based on mechanical input. Installation of the cover plate automatically triggers locking through the locking rod engaging the locking groove, and applying vertical force automatically triggers unlocking, eliminating the need for separate manual operations for each function
4Object-affected harmful factors
If locking rods are used without button operation, then button-related dirt issues are eliminated, but the structure becomes more complex
Solution Approach 1:
The locking mechanism is divided into distinct functional segments: the locking rod with its elastic portion, the locking groove with positioning protrusions, and the support abutting block. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity, avoiding the need for complex button mechanisms

AI summary
The present disclosure discloses an assembly-and-disassembly structure for a toilet cover, which comprises a cover plate assembly, two support bases, and two rotation shafts. A torsion spring is disposed between the first locking rod and the second locking rod. A first end of the torsion spring is movably connected to the first locking rod, and a second end of the torsion spring is connected to the second locking rod. The second locking rod comprises a torsion spring fixing portion. An outer end of the first locking rod comprises a first locking plate, and an inner end of the first locking rod comprises a sliding groove structure configured to receive the first end of the torsion spring to move.
