Solution Overview

Problem

Existing methods for cleaning lap siding, such as power washing and using soft brushes, are ineffective in reaching and removing dirt and debris from the under surface of overlapping boards, leading to rapid regrowth of mildew, mold, and algae.

Innovation Solution

A scrubber with an elongated base and pivotally connected handle, equipped with a removable scrubbing cover or pad, designed to fit the profile of lap siding, allowing for effective cleaning of both the face and under surface by applying light to moderate pressure at an upward angle, ensuring full contact with the siding surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a soft brush on a pole is used to clean lap siding, then the face of the siding can be cleaned, but the under surface of the overlapping boards cannot be reached

Engineering Contradiction:
Improvecleaning capabilityVSAvoidcleaning effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The scrubber is divided into distinct functional segments: an elongated base for reaching under surfaces, a scrubbing cover with bristles for cleaning, and a handle for operation. This segmentation allows each part to perform its specific function effectively, with the base configuration enabling access to previously unreachable areas under overlapping boards

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a simple linear brush to a three-dimensional scrubber with an elongated base that extends beneath the overlapping boards. This dimensional change allows the scrubbing surface to contact both the face and the under surface of the siding simultaneously, overcoming the limitation of traditional two-dimensional brush contact

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If power washing is used to clean lap siding, then water can be forced onto the surface, but it may damage the siding and is not totally effective without mechanical agitation

Engineering Contradiction:
Improvecleaning speedVSAvoidsiding damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The scrubber merges the functions of water application and mechanical scrubbing into a single integrated tool. The scrubbing cover combines with the elongated base to provide both gentle water delivery and physical agitation through bristle contact, achieving effective cleaning without the high-impact water pressure that could damage siding

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention changes the pressure parameter from high-impact power washing to light to moderate manual pressure applied through the scrubber. This parameter change allows effective cleaning through mechanical agitation while avoiding the harmful effects of excessive water pressure on the siding material

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If lap siding is designed to shed water, then water drainage is improved, but water cannot be effectively shot up into the overlap seam for cleaning

Engineering Contradiction:
Improvewater shedding functionVSAvoidcleaning accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The elongated base is configured with a curved or contoured shape that complements the profile of the lap siding and overlap seams. This curvature allows the base to follow the contours of the siding and insert itself beneath the overlapping boards, providing access to areas that straight rigid tools cannot reach while maintaining the siding's water shedding geometry

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A scrubber for lap siding with a profile complementary to the profile of the boards in the lap siding such that when the scrubber is moved side to side in a washing action, an exposed side face and under surface of the siding boards are effectively scrubbed and dirt, dust, mildew, mold and algae are effectively removed.
