Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking assemblies for toilet covers, whether made of plastic or metal, face issues such as creep and loosening over time, difficulty in rapid installation or disassembly, and risk of damage from improper installation or violent disassembly.
Innovation Solution
A locking assembly comprising a retainer with sliding grooves, a hinge shaft, and fastening sheets hinged to the hinge shaft, which can move between disengagement and engagement states, and an actuating positioner with a bolt and threaded hole to facilitate rapid disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic or rubber expansion bolts are used, then installation is simple and rapid, but they creep and loosen after long-term use
Solution Approach 1:
The locking assembly uses a composite structure combining metal components (screw rod, locking piece) with plastic/rubber components (expansion bolt). The metal parts provide long-term stability and anti-creep properties, while the expansion bolt maintains installation simplicity. The locking piece with limiting structures works with the screw rod to prevent loosening, while the overall assembly remains easy to install using the expansion bolt mechanism.
2Reliability
If metal locking assemblies are used, then long-term stability is improved, but they cannot be rapidly installed or disassembled
Solution Approach 1:
The locking assembly is divided into separate functional segments: the expansion bolt for rapid installation, the screw rod for positioning, and the locking piece with limiting structures for stability. This segmentation allows each component to perform its specific function efficiently - the expansion bolt enables quick installation while the metal locking piece maintains long-term stability without requiring complex manual manipulation of the entire assembly.
3Strength
If metal locking assemblies are used, then strength is improved, but they are likely to be damaged when improperly installed or violently disassembled
Solution Approach 1:
The locking piece acts as an intermediary between the screw rod and the installation support, providing a buffering mechanism. The limiting structures on the locking piece allow controlled movement and positioning, preventing direct transmission of impact forces that could damage the metal components during improper installation or violent disassembly attempts.
4Productivity
If expansion bolts are made of plastic or rubber, then installation is rapid, but they are likely to be damaged when violently installed
Solution Approach 1:
The assembly combines plastic/rubber expansion bolt with metal locking components. The plastic expansion bolt maintains rapid installation capability while the metal locking piece and screw rod provide impact resistance and structural strength, protecting the softer plastic components from damage during violent installation or disassembly.
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 locking assembly allows for rapid and reusable installation and disassembly, reducing the risk of damage and maintaining stability over time, while also accommodating the specific requirements of toilet cover installation.
Implementation Method 1
the actuating positioner comprises a bolt and a threaded through hole radially formed in the hinge shaft, the bolt penetrating the retainer to be connected to the threaded through hole
Implementation Method 2
the first sliding groove being provided with a first inclined guide surface for engaging the first fastening sheet relative to the second fastening sheet, the second sliding groove being provided with a second inclined guide surface for engaging the second fastening sheet relative to the first fastening sheet
Implementation Method 3
parts, close to hinge ends, of the connecting plates of the first fastening sheet and the second fastening sheet being provided with cut grooves separately; and the limiting structure enabling an end part of the hinge end of the first hinge plate of the first fastening sheet to be in abutting fit with a bottom of the cut groove of the second fastening sheet, and an end part of the hinge end of the first hinge plate of the second fastening sheet to be in abutting fit with a bottom of the cut groove of the first fastening sheet
