Elevator track cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for elevator tracks are inefficient and costly, requiring expensive steel alloy brushes and being labor-intensive, with prior solutions failing to effectively maintain a bright metal shine through frequent, light cleaning.
Innovation Solution
A rectangular scrub brush configuration with a platform, raised handle, stiff flexible bristles, and small hooks to secure a flexible scrub pad, allowing for easy attachment and effective cleaning of elevator tracks with reduced effort and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive tiger claw steel alloy brushes are used to clean elevator tracks, then cleaning effectiveness is improved, but device cost increases
Solution Approach 1:
The patent replaces expensive, durable tiger claw steel alloy brushes with inexpensive disposable scrub pads made from materials like Scotch-Brite® or other abrasive pads. These pads are attached to a simple platform and can be easily replaced when worn, eliminating the need for costly specialized steel brushes while maintaining cleaning effectiveness.
Solution Approach 2:
The invention changes the material parameters from expensive metal alloy (tiger claw steel) to affordable abrasive materials. The scrub pads use abrasive compounds embedded in a flexible substrate, transforming the cleaning mechanism from mechanical steel-to-steel abrasion to a more cost-effective abrasive pad system that achieves the same cleaning results at lower cost.
2Reliability
If traditional elevator track cleaning devices are used, then cleaning capability is maintained, but labor intensity increases
Solution Approach 1:
The cleaning device is segmented into a simple platform base with interchangeable scrub pads, allowing workers to quickly swap pads between different elevator tracks without retooling. This modular design reduces the physical effort and time required for cleaning multiple tracks compared to traditional fixed-design brushes.
Solution Approach 2:
The scrub pads are designed with flexible, dynamic properties that adapt to the contour of the elevator track groove. The flexible pad material conforms to the track geometry, maintaining consistent contact and cleaning pressure without requiring the worker to apply excessive force, thereby reducing labor intensity.
3Duration of action of stationary object
If infrequent heavy cleaning is performed on elevator tracks, then maintenance frequency is reduced, but cleaning effectiveness decreases
Solution Approach 1:
The disposable scrub pads enable a periodic maintenance schedule where light cleaning can be performed frequently with minimal effort. The pads are designed for single-use or limited-use applications, encouraging regular replacement and frequent light cleaning rather than infrequent heavy cleaning, thereby maintaining bright metal shine through consistent maintenance.
Solution Approach 2:
The scrub pads are designed to be self-contained and disposable, requiring no complex maintenance or refurbishment. Workers can simply attach a new pad to the platform and begin cleaning immediately, enabling frequent light cleaning operations without requiring specialized equipment maintenance or extensive worker training.
Applied Scientific Principles

AI summary
The invention is directed to an elevator track cleaner. The track cleaner is provided in a rectangular scrub brush configuration, providing a platform with a raised handle affixed to the top surface. The bottom surface provides a longitudinal band of stiff, flexible bristles along the centerline, and two longitudinal bands of small hooks on either side of the bristles for the purpose of securing a flexible white scrub pad. The pad is used to scrub the elevator track, with the bristles urging the pad into the groove where the track is located.
