Solution Overview

Problem

Existing slides have high frictional resistance, limiting sliding speed and reducing entertainment value, while also being safety-constrained by small height or closed designs.

Innovation Solution

A composite coating method using a water-based two-component polyurethane topcoat and a nano-silicon varnish is applied to the slide, with specific steps including uniform stirring, rolling patterns with a sponge embossing roller, and multiple coats of varnish to reduce friction and enhance adhesion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the slide surface is made smooth to reduce friction, then sliding speed increases, but adhesion between coating layers deteriorates

Engineering Contradiction:

Improvesliding speedVSAvoidcoating adhesion

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent applies different surface treatments to different layers: the bottom coat maintains a rough surface for adhesion, while the top coat provides a smooth surface for low friction. This local differentiation resolves the contradiction between adhesion and sliding speed.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses a composite coating structure with two distinct layers having different properties. The bottom layer provides adhesion with a rough surface, while the top layer provides low friction with a smooth surface, resolving the contradiction through material composition.

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If the slide height is increased to improve entertainment value, then excitement increases, but safety risks increase

Engineering Contradiction:

Improveentertainment valueVSAvoidsafety risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies a flexible composite coating film on the slide surface that reduces friction to enhance sliding speed and entertainment value without requiring increases in slide height, thereby maintaining safety.

Inventive Principle:

3Reliability

If a rough surface is used to enhance coating adhesion, then coating firmness improves, but frictional resistance increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent divides the coating into two separate layers with distinct functions: the bottom layer has a rough surface for adhesion, while the top layer has a smooth surface for low friction. This segmentation resolves the contradiction between firmness and sliding speed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different surface characteristics are applied to different layers: the bottom coat surface is rough for adhesion, while the top coat surface is smooth for low friction, allowing both adhesion and speed requirements to be met simultaneously.

Inventive Principle:

Principle #3Local quality

AI summary

A composite coating includes a water-based two-component polyurethane topcoat and a nano-silicon varnish. The coating method of the composite coating on the slide includes uniformly stirring the water-based two-component polyurethane topcoat, then coating the surface of the slide with the water-based two-component polyurethane topcoat; rolling patterns on the surface of the water-based two-component polyurethane topcoat by using a sponge embossing roller before the surface of the water-based two-component polyurethane topcoat dries; and after rolling is completed, place to dry, and then coat the nano-silicon varnish to form a smooth surface after confirming the surface of the water-based two-component polyurethane topcoat has dried. The sponge embossing roller is used for rolling the patterns before the water-based two-component polyurethane topcoat has not dried, so that the contact area with the nano-silicon varnish is increased, indirectly promoting the adhesion ability of the nano-silicon varnish and ensuring the firmness of the composite coating.
