Pivotable Wheel Brush with Lug Nut Cavity Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel and lug nut cleaning tools are inadequate as they often require multiple devices, lack sufficient cleaning force, have underpowered motors, and can scratch vehicle surfaces due to exposed metal parts, and fail to clean hard-to-reach areas like inner wheel rims and rim cavities around lug nuts.
Innovation Solution
A single integrated wheel and lug nut cleaning device with a pivotable brush head and lug nut cavity-cleaning body featuring a resilient non-abrasive brush and flexible microfiber flanges, designed to clean both outer and inner wheel rims, lug nuts, and rim cavities without scratching, and includes a knuckle guard for user protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate cleaning devices are used for wheel and lug nut cleaning, then each device can be optimized for its specific function, but the overall cleaning process becomes complex and time-consuming
Solution Approach 1:
The patent combines wheel cleaning and lug nut cleaning functions into a single integrated device. The handle assembly includes both a wheel cleaning brush at one end and a lug nut cleaning brush at the other end, allowing users to perform both cleaning tasks with one tool rather than requiring separate devices, thereby improving productivity while reducing device complexity
Solution Approach 2:
The cleaning device is designed with multi-functionality to address various cleaning needs. The handle serves as a common structure supporting both wheel cleaning and lug nut cleaning brushes, while the adjustable brush positions and different brush types enable the single device to handle different cleaning scenarios effectively
2Ease of operation
If an elongated handle is used in cleaning tools, then the device can reach difficult areas, but insufficient force is transmitted for vigorous cleaning
Solution Approach 1:
The patent employs dynamic elements including spring-loaded brush holders that allow the brushes to flex and adapt to the cleaning surface. The springs enable the brushes to maintain contact pressure on irregular surfaces while allowing users to apply vigorous force without breaking the handle, thus resolving the contradiction between reach and cleaning force transmission
3Device complexity
If metal parts are exposed in the handle to hold bristles, then the structure is simple and durable, but the metal can scratch and damage the rim surface paint and clear coat
Solution Approach 1:
The patent uses flexible, non-metallic materials such as springs and plastic components in the brush holder assembly. These flexible elements replace exposed metal parts that could scratch the paint, while still providing the necessary structural support and bristle retention. The flexible materials conform to the rim surface without causing damage, thus eliminating the harmful scratching effect while maintaining structural integrity
4Power
If a motorized cleaner is used, then cleaning power is increased, but the device requires battery replacement or extension cord connection
Solution Approach 1:
The patent employs a manual cleaning device that derives its cleaning power from the user's hand movements rather than requiring an external power source. The spring-loaded mechanisms and lever actions convert user input directly into effective cleaning force, eliminating the need for batteries or extension cords. This self-service approach provides sufficient cleaning power through mechanical advantage while avoiding the complexity of power supply systems
5Loss of time
If a single integrated device is used for wheel and lug nut cleaning, then the cleaning process is simplified and time is saved, but the device must effectively clean both outer wheel rim and inner wheel rim behind spokes
Solution Approach 1:
The patent divides the cleaning device into distinct functional segments: a wheel cleaning brush for the outer rim, a lug nut cleaning brush for the lug nuts, and an adjustable positioning mechanism. This segmentation allows each component to be optimized for its specific cleaning task while being integrated into a single handle assembly, enabling the device to adapt to different wheel areas without requiring multiple separate tools
