Scrubber Machine Controls for Faster Hands-Free Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scrubber machines require significant operator effort and time to adjust features such as side skirts, brush tension, and direction control, which hampers ergonomics and performance.
Innovation Solution
The development of improved mechanisms for scrubber machines, including a skirt mechanism with a latch system for easy adjustment of side skirts, a self-contained drive mechanism, and a forward/reverse throttle pedal that allows for single-motion control of direction, reducing operator effort and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional side skirt adjustment mechanisms are used, then the side skirts can be adjusted, but significant operator effort and time are required
Solution Approach 1:
The side skirt mechanism uses a dynamic latch system that can be quickly engaged and disengaged, allowing the side skirt to be rapidly adjusted between different positions without requiring significant operator effort or time
Solution Approach 2:
The side skirt mechanism is designed to be self-adjusting through the latch system, which automatically secures the side skirt in place once positioned, reducing the need for continuous operator intervention and minimizing adjustment time
2Ease of operation
If traditional brush tension adjustment mechanisms are used, then brush tension can be changed, but operator effort and time are required
Solution Approach 1:
The brush tension mechanism employs a dynamic adjustment system that allows rapid change of tension settings through a latch-based mechanism, enabling operators to quickly adapt brush tension to different cleaning requirements without time-consuming manual adjustments
3Ease of operation
If traditional direction control mechanisms are used, then forward and reverse directions can be switched, but operator effort and time are required
Solution Approach 1:
The direction control mechanism uses a dynamic latch system that enables rapid switching between forward and reverse directions with minimal operator effort, allowing the scrubber to quickly adapt to changing operational requirements
4Ease of operation
If traditional rear squeegee assembly installation mechanisms are used, then the squeegee can be installed, but operator effort and time are required
Solution Approach 1:
The rear squeegee assembly uses a dynamic latch-based mounting system that allows rapid installation and removal, enabling operators to quickly attach or detach the squeegee without requiring significant effort or time
Solution Approach 2:
The squeegee assembly is designed with self-aligning features that guide the component into proper position during installation, reducing operator effort and minimizing installation time
5Ease of operation
If traditional disc-type and roller-type brush installation mechanisms are used, then brushes can be installed, but operator effort and time are required
Solution Approach 1:
The brush installation mechanism employs a dynamic latch system that enables rapid attachment and removal of disc-type and roller-type brushes, allowing operators to quickly change brushes without requiring significant effort or time
Solution Approach 2:
The brush mounting system includes self-aligning features that guide brushes into proper position during installation, reducing operator effort and minimizing installation time
