Solution Overview

Problem

Existing tools for adjusting filler strips to irregular walls and ceilings are laborious and can cause damage, failing to efficiently adapt prefabricated strips to surface imperfections.

Innovation Solution

A parallel rolling gauge with a continuously adjustable sliding carriage and a plastic-coated roller stylus, allowing for precise transfer of wall irregularities to a marking tool, enabling easy adaptation of filler strips without damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If existing tools are used to adjust filler strips to irregular walls, then the strips can be adapted to surface imperfections, but the process becomes laborious and time-consuming

Engineering Contradiction:

Improveadaptation precisionVSAvoidadjustment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The device creates a direct copy of the wall's irregular surface profile by using a follower roller that traces the wall contours and transfers them to the marking tool, eliminating the need for manual measurement and adjustment steps

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated mechanical tracing system where the follower roller automatically follows the wall profile and the parallel linkage system automatically transfers this profile to the marking point

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If existing marking tools are used on irregular walls, then the filler strips can be marked for adaptation, but the tools cause damage such as scratches on the walls

Engineering Contradiction:

Improvemarking accuracyVSAvoidwall damage

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The follower roller acts as an intermediary between the wall surface and the marking process, gently tracing the wall profile without direct contact from harsh marking tools, thus preventing wall damage while maintaining marking accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the contact parameter by using a roller instead of a point-contact marking tool, distributing the contact force over a larger surface area and reducing pressure intensity to prevent wall damage

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If manual adjustment methods are used for filler strips, then adaptation to wall irregularities is possible, but the process lacks precision and efficiency

Engineering Contradiction:

Improveadaptation flexibilityVSAvoidprofile transfer accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The device creates a precise geometric copy of the wall profile through parallel mechanical linkages that ensure the marking tool reproduces the exact contours traced by the follower roller, achieving high measurement precision while maintaining adaptability

Inventive Principle:

Principle #26Copying
