Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press water drop head devices in drainage equipment generate noise during use and are difficult to clean, requiring replacement of the entire unit when the bounce switch component fails, leading to increased maintenance costs and user inconvenience.
Innovation Solution
A press water drop head device with a simple and compact structure featuring a bounce component with a fixing casing, sliding block, pressing spring, and sliding guide rod, allowing for quick removal and replacement of the bounce component without affecting other parts, reducing noise and maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bounce switch component is fixed by thread glue, then the component is securely fixed, but the entire drain rod must be replaced when the bounce switch fails, increasing maintenance costs
Solution Approach 1:
The drain rod is divided into modular components: the bounce switch component, the rod body, and the water drop head. Each component can be independently removed and replaced. The bounce switch component is fixed to the rod body through a snap-fit structure with positioning protrusions and grooves, allowing quick replacement without replacing the entire drain rod.
Solution Approach 2:
The bounce switch component is designed as a replaceable module that can be discarded when failed and recovered for replacement. The snap-fit connection allows the old bounce switch to be quickly removed and a new one installed, recovering the functional capability without waste of the entire drain rod assembly.
2Device complexity
If the bounce switch component is fixed by thread glue, then the component structure is simple, but the entire drain rod needs to be removed for cleaning when the water drop head is blocked
Solution Approach 1:
The drain rod is segmented into independently removable components. The water drop head can be separated from the rod body through the modular connection structure, allowing users to access and clean the interior passage without removing the entire drain rod assembly.
Solution Approach 2:
The modular connection structure is pre-designed with positioning protrusions and grooves that guide the assembly and disassembly process. Users can quickly detach the water drop head for cleaning by simply aligning and separating the components, without needing to perform complex disassembly actions.
3Reliability
If the bounce switch component uses thread fixation, then the component is securely attached, but noise is generated during pressing operations
Solution Approach 1:
The thread fixation method is extracted and replaced with a snap-fit connection structure. The bounce switch component is attached to the rod body through elastic deformation of the rod material, which provides secure attachment without the noise-generating thread engagement during pressing operations.
Solution Approach 2:
The snap-fit connection uses a simple elastic deformation mechanism rather than permanent thread fixation. The positioning protrusions and grooves provide reliable attachment that can be quickly released and reattached, reducing noise during operation while maintaining component security.
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 device reduces noise during operation, prevents water leakage, saves time during cleaning, and lowers maintenance costs by allowing for selective replacement of the bounce component, enhancing user safety, energy efficiency, and environmental protection.
Implementation Method 1
a pressing spring vertically disposed, one end of the pressing spring being fixedly connected to the bottom end of the sliding block, and the other end being disposed in the fixing casing
Implementation Method 2
a sliding block vertically slidably sleeved in the fixing casing
