Janitorial Cart Ramp Coupling for Lift-Free Mop Bucket Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Janitors face the challenge of having to separately roll heavy mop buckets and trash can dollies or janitorial carts to cleaning locations, as existing mechanisms require lifting the mop bucket to connect them, causing strain and inefficiency.
Innovation Solution
A mechanism with a downwardly extending ramp section and return springs allows the trash can dolly or janitorial cart to be easily attached to the mop bucket without lifting, using a foot-activated button to lower the ramp section and secure it underneath, enabling simultaneous rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mop bucket is lifted to be inserted over the interconnecting member, then the trash can dolly and mop bucket can be connected, but the janitor experiences stress and strain due to the heavy weight of the filled mop bucket
Solution Approach 1:
Instead of lifting the mop bucket onto a stationary interconnecting member, the interconnecting member is inverted to move upward with a ramp section that receives the mop bucket as it rolls forward. This reverses the traditional connection approach, allowing the lighter dolly to actively engage the heavier bucket without requiring the operator to lift the bucket.
Solution Approach 2:
The interconnecting member transitions from a static structure to a dynamic one with a movable ramp section that can be lowered and raised. The ramp section moves downward to receive the mop bucket and then returns to its initial position, creating a dynamic connection mechanism that adapts to the weight and motion of the mop bucket.
2Strength
If the interconnecting member is made heavy-duty to support the filled mop bucket, then the connection strength is improved, but the activation force required to operate the mechanism increases
Solution Approach 1:
Return springs are incorporated into the interconnecting member to provide a counterbalancing force that offsets the weight of the heavy-duty ramp section. These springs store mechanical energy when the ramp is lowered and release it to automatically return the ramp to its initial position, reducing the activation force needed to operate the mechanism while maintaining the structural strength required to support filled mop buckets.
3Ease of operation
If a simple rolling motion is used to connect the dolly and mop bucket, then the ease of operation is improved, but the connection reliability may be compromised
Solution Approach 1:
The mop bucket is designed to nest within the frame structure of the trash can dolly when connected. The bucket's base wall receives onto the ramp section, and the bucket's sidewalls engage with the dolly's frame members, creating a nested configuration where the lighter dolly frame supports and stabilizes the heavier bucket, ensuring reliable connection through the rolling motion.

AI summary
A unique attachment mechanism whereby a base platform of a janitorial cart can be affixed to the underside of a mop bucket by an interconnection mechanism by a simple rolling motion so that it is not necessary to lift a heavy mop bucket filled with water to interconnect the mop bucket and the base platform of a janitorial cart.
