Solution Overview

Problem

Existing caulking tools require separate devices for reshaping caulk after application, which can be inconvenient and inefficient, especially when aiming for a precise or aesthetically pleasing caulk profile.

Innovation Solution

A caulk reshaping tool adapted for use with a caulk gun, featuring a base plate and elongated portion that encircles the nozzle, allowing for integrated scraping and reshaping of the caulk bead without the need for additional tools, with optional replacement tips and adjustable configurations for various applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a separate caulk working tool is used for reshaping after caulk application, then the caulk can be smoothed to achieve desired profile, but the process requires multiple tools and steps increasing device complexity and operation time

Engineering Contradiction:
Improvecaulk profile precisionVSAvoidnumber of tools required
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the caulk application function and the reshaping function into a single integrated tool. The caulk gun assembly includes both the cartridge holder for dispensing caulk and an attached working tool with a blade for reshaping, eliminating the need for separate tools and reducing operational complexity while maintaining precise caulk profile control

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If a separate caulk working tool is used for reshaping after caulk application, then the caulk can be smoothed to achieve desired profile, but the process requires additional time and steps

Engineering Contradiction:
Improvecaulk profile precisionVSAvoidcaulk working time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges the caulk dispensing and reshaping operations into a single continuous action. The integrated tool allows the user to apply caulk and immediately reshape it in one motion, eliminating the time required to switch between tools and perform separate reshaping steps, thereby reducing overall operation time while achieving precise caulk profiles

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If the elongated portion has a larger width at the first end, then it provides structural strength and stability, but it increases the overall size of the device

Engineering Contradiction:
Improveelongated portion strengthVSAvoiddevice size
Core Design Contradiction:
StrengthVSLength of moving object

Solution Approach 1:

The elongated portion is designed with an asymmetric cross-section where the first end (proximal to the base plate) has a larger width than the second end (distal end). This asymmetric geometry provides enhanced structural strength and stability at the base while tapering to a narrower profile at the working end, optimizing both strength and compactness without requiring the entire device to be oversized

Inventive Principle:
Principle #4Asymmetry

AI summary

A device for scraping caulk is adapted to be used with a caulk gun. The device includes a base plate having a central void and an elongated portion extending from the base plate along an axis perpendicular to the base plate. The device can be fitted between a caulk tube and a caulk gun to allow the application of caulk and the scraping/reshaping of the caulk in a single run. The device can include different replacement tips useful for different applications and different desired results.
