Buffing Pad Washer With Manual Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffing pad cleaning devices suffer from decreased cleaning solution effectiveness as it becomes dirtier and degrades due to recirculation, leading to reduced pad cleaning performance.
Innovation Solution
A manually operated positive displacement pump system that delivers cleaning solution to the buffing pad through a foraminous wash plate, allowing for fresh solution application and improved dirt removal, supported by a base plate and catch basin for efficient solution return and filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning solution is recirculated and reused in the reservoir, then the system maintains continuous operation, but the cleaning solution becomes dirtier and degrades, reducing pad cleaning performance
Solution Approach 1:
The patent extracts the dirty cleaning solution from the reservoir and removes it from the recirculation loop. A drain at the bottom of the reservoir allows the dirty solution to be emptied, and fresh solution can be replenished. This prevents the degradation that occurs with continuous recirculation while maintaining operational continuity.
Solution Approach 2:
The system discards the degraded cleaning solution by draining it from the reservoir and recovers fresh solution by allowing replenishment. The catch basin captures and holds the discarded dirty solution separately, enabling the operator to empty and refill the reservoir with clean solution to restore cleaning effectiveness.
2Reliability
If a manually operated positive displacement pump is used to deliver cleaning solution, then solution freshness is maintained, but the device complexity increases compared to recirculation systems
Solution Approach 1:
The manual positive displacement pump is operated by the operator's hand movements, eliminating the need for an electric motor or complex automated pumping system. The operator simply moves the pump handle to deliver fresh solution from the reservoir to the wash plate, maintaining solution effectiveness while keeping the system simple and easy to operate.
3Productivity
If the wash plate is designed to be contacted by the buffing pad during rotation, then cleaning action is effective, but the apparatus must be compatible with multiple machine types
Solution Approach 1:
The wash plate is designed with a universal interface that can accommodate pads from different buffing machine types including rotary, dual action, and random orbital machines. The wash plate's flat surface and positioning system allow it to work effectively with various pad orientations and rotation patterns, making the apparatus versatile across multiple machine types while maintaining effective cleaning action.

Function Achieved in This Case
Enhances cleaning performance by maintaining solution freshness and effectiveness, improving dirt removal from buffing pads, and allowing for easy cleaning of pads on various machine types without the need for continuous recirculation.
Implementation Method 1
A positive displacement pump in the reservoir is operated in response to the operator applying vertical reciprocating movement to the pad contact face
Implementation Method 2
The biasing arrangement comprises a plurality of compression springs that are captured between the lower wash plate surface and the base plate support surface
Implementation Method 3
A positive displacement pump is mounted in the reservoir and includes a cleaning solution inlet on a lower end and a housing that includes a cleaning solution outlet on an upper end in liquid communication with the wash plate

AI summary
A cleaning apparatus for a power driven buffing pad includes a wash plate mounted in a cleaning solution reservoir that provides agitating and cleaning contact with the pad mounted on an operating driver. The wash plate can be reciprocated vertically by the operator against a biasing arrangement to operate a pump to deliver cleaning solution from the reservoir to the face of the pad in contact with the wash plate.
