Solution Overview
Problem
Conventional cleaning tools struggle to effectively clean hard-to-reach and inaccessible areas, such as stainless steel and glass surfaces, and are not durable enough to withstand harsh chemicals.
Innovation Solution
A cleaning applicator with an elliptical bulb, a polypropylene handle, and embedded abrasive materials, including grit particles and studs, designed to scrub and scour these surfaces, with a polypropylene handle for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cleaning tools are used, then they can clean accessible surfaces, but they cannot effectively clean hard-to-reach and inaccessible areas
Solution Approach 1:
The cleaning tool is segmented into distinct functional components: a bulb-shaped applicator head with multiple cleaning surfaces (abrasive skin, padding, and grit-embedded tip), allowing each segment to address different cleaning needs in hard-to-reach areas. The modular design enables the tool to navigate complex geometries while maintaining cleaning effectiveness.
Solution Approach 2:
Different portions of the cleaning applicator have specialized local properties: the tip embeds abrasive grit for scrubbing, the skin provides scouring action, and the padding offers gentle cleaning. This local differentiation allows the single tool to effectively clean various surfaces in hard-to-reach areas with different contamination levels and surface types.
2Reliability
If conventional cleaning tools are used, then they can perform basic cleaning, but they are not durable enough to withstand harsh chemicals
Solution Approach 1:
The cleaning applicator employs composite material construction: the bulb and handle are made from chemically resistant polypropylene, while the cleaning surfaces utilize abrasive materials (grit, skin with abrasive particles) that are both durable and chemically inert. This composite approach ensures the tool withstands harsh chemicals while maintaining cleaning effectiveness.
3Ease of operation
If a bulb shape is used for the cleaning applicator, then it can reach into crevices, but it reduces the structural strength
Solution Approach 1:
The cleaning applicator features a bulb-shaped head with smooth curved surfaces that naturally fit into crevices and contours. The curved geometry provides mechanical strength by distributing stress evenly, while the elongated bulb shape maintains adequate structural integrity despite the rounded form factor.
Solution Approach 2:
The polypropylene material provides both the necessary structural strength and chemical resistance, while the bulb shape optimizes access to crevices. The composite construction of the bulb (combining polypropylene with embedded abrasive elements) maintains strength despite the curved, cavity-accessing geometry.

AI summary
A cleaning applicator has a bulb in the shape of an oval and a stem at one end and a handle end configured to receive the bulb stem and a skin made to fit the bulb and embedded with a cleaning abrasive. A padding fits the bulb underneath the skin to help in cleaning and scouring with the tip of the cleaning applicator. The bulb oval shape is elliptical and it can be egg-like with the stem at the larger end of the egg-like oval. The stem is threaded and the handle has a complementary thread to receive the stem. The handle comprises polypropylene and the bulb can include polypropylene.
