Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closestool cover plate quick installation and disassembly mechanisms are complex and laborious, with single-button control systems requiring high force to operate due to multiple springs, and are unreliable when one of the button mechanisms malfunctions.
Innovation Solution
A quick installation hinge seat with two hinge shafts, support seats, and a button switch featuring a lock control rod with locking and unlocking plates, a resilient trigger device, and a spring for self-locking functionality, allowing easy assembly and disassembly with reduced operational force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-button control connecting structure with multiple springs is used, then the button can be operated conveniently, but it requires high force to press the button due to the elasticity of multiple springs
Solution Approach 1:
The invention divides the button control system into two independent button mechanisms instead of using a single button. Each button mechanism has its own spring, so when one button is pressed, only one spring's elastic force needs to be overcome, reducing the required pressing force while maintaining operational convenience
Solution Approach 2:
The invention uses two buttons instead of one, where each button performs the same function partially. This redundancy allows the system to maintain functionality even if one button mechanism malfunctions, while each individual button requires less force to operate since it only needs to overcome one spring's elasticity
2Ease of operation
If a single-button control system with multiple springs is used, then the button can be operated conveniently, but the system complexity increases due to multiple springs and components
Solution Approach 1:
The invention segments the control system into two independent, identical button mechanisms. Each mechanism is simpler with only one spring, making them easier to manufacture and maintain. The overall system complexity is managed through modular repetition rather than complex integration of multiple springs in a single mechanism
Solution Approach 2:
The invention changes the structural parameter from a single complex button mechanism with multiple springs to two simpler button mechanisms with single springs each. This parameter change simplifies the individual components while achieving the same functional outcome through redundancy
3Device complexity
If a single-button control system is used, then the structure can be compact, but the reliability decreases when one of the button mechanisms malfunctions
Solution Approach 1:
The invention applies local quality by creating two identical button mechanisms with the same functional properties. Each mechanism is designed to be independently reliable, and the redundancy ensures that the overall system reliability is maintained even if one local mechanism fails
Solution Approach 2:
The invention provides beforehand cushioning by having a redundant button mechanism ready in advance. If one button mechanism malfunctions, the other is already in place to take over the function, ensuring continuous operational reliability without requiring any corrective action
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 solution simplifies the assembly and disassembly process, reduces the force required to operate the button, and enhances reliability by using a single spring for return and self-locking mechanisms, ensuring the cover plate can be quickly mounted and dismounted with ease.
Implementation Method 1

AI summary
A quick installation hinge seat of a closestool cover plate includes two hinge shafts and two support seats. Each hinge shaft has a pin hole for connection of a pin provided on each support seat. A button switch is mounted between the two hinge shafts to control the pin in the pin hole. The button switch includes a hinge pipe, a button seat, a lock control rod slidable in the radial direction of the hinge pipe, a spring, and a button to press the lock control rod. Two ends of the lock control rod are axially inserted in the two hinge shafts respectively and slideable radially. Each of the two ends of the lock control rod has a locking plate and an unlocking plate. The locking plate and the unlocking plate are arranged in a stagger manner. Each pin has a locking groove and an unlocking groove thereon.
