Solution Overview

Problem

Existing methods for constructing paver installations struggle to ensure uniformity and controlled depth of both base and top layers, making it difficult to achieve a high-quality finished installation.

Innovation Solution

A bed-depth gauge comprising a guide member and a screed member with adjustable assembly means, allowing for precise control of layer depth and uniformity, featuring a guide member with lateral arms and a screed member with parallel slots and studs for easy adjustment and alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional methods are used for distributing base and top layer materials, then the construction process is simple, but the uniformity and depth control of layers cannot be ensured

Engineering Contradiction:

Improvelayer depth uniformityVSAvoidtool structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the guide member and screed member into a single integrated bed-depth gauge tool. The guide member with its panel and arms are assembled to the screed member through slots and studs, creating one unified tool that simultaneously provides depth control and material distribution functions, thereby achieving layer uniformity without requiring multiple separate tools

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bed-depth gauge is designed as a multi-functional tool that can control the depth of both base layer and top layer materials. The adjustable assembly mechanism allows the same tool to accommodate different depth requirements for different layers, making it a universal solution for various paver installation scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If fixed-depth tools are used, then the tool structure is simple, but the adaptability to different paver heights is limited

Engineering Contradiction:

Improveadjustability to paver heightVSAvoidadjustment convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a dynamic adjustment mechanism where the screed member can move vertically relative to the guide member along slots. The studs engage with the slots to allow smooth adjustment of the distance between the guide panel bottom edge and screed member bottom edge, enabling the tool to adapt to different paver heights while maintaining ease of operation through simple manual adjustment

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The tool is divided into separable components (guide member with arms and screed member) that can be independently adjusted and repositioned. The slots and studs system allows each component to be positioned at the required depth setting and then locked in place, providing both adaptability and operational simplicity

Inventive Principle:

Principle #1Segmentation

AI summary

A bed-depth gauge consists of a guide member, a screed member, and means for assembling them for relative movement, for effective depth adjustment, in a vertical direction that is generally perpendicular to a bottom edge of the screed member. The guide member has a pair of arms that extend laterally, at different heights, which are used to engage and follow a fixed reference surface to thereby enable the bottom edge of the screed member to level and control the depth of both a base layer and also an overlying upper layer, comprising a bed prepared for installation of paving blocks and the like.
