Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corded wet surface cleaners are limited by cord length and require constant access to power sources, while existing cordless models often have inefficient tank designs that complicate maintenance and battery replacement.
Innovation Solution
A cordless wet surface cleaner design featuring removable supply and recovery tanks that form the outer perimeter, with a rechargeable battery positioned between the tanks, allowing easy access and maintenance, and a battery mount that directs fluid away from electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If corded wet surface cleaners are used, then continuous power supply is ensured, but cord length limits mobility and constant access to power sources is required
Solution Approach 1:
The power supply system is segmented into a removable battery unit that can be detached and replaced independently from the main cleaner body. This allows the battery to be recharged separately while maintaining continuous operation capability of the cleaner itself.
Solution Approach 2:
The battery is extracted as a separate, removable component from the cleaner assembly. This extraction enables independent battery maintenance and charging, eliminating the need for constant access to power sources during cleaner operation.
2Ease of operation
If existing cordless models are used, then mobility is improved, but tank designs complicate maintenance and battery replacement
Solution Approach 1:
The cleaner is divided into three independently removable segments: supply tank, recovery tank, and battery. Each component can be accessed and maintained separately without disassembling other parts, greatly simplifying maintenance procedures.
Solution Approach 2:
The tanks and battery are designed as extractable components that can be easily removed from the main body. The supply tank and recovery tank can be detached for cleaning and maintenance, while the battery can be independently removed for replacement or recharging.
3Quantity of substance
If tanks are positioned to maximize liquid capacity, then debris collection volume is increased, but access to battery and maintenance areas becomes difficult
Solution Approach 1:
The tank assembly is segmented into supply and recovery sections that can be independently removed. This segmentation allows maximum tank capacity while maintaining easy access to the battery and other components through separate removal paths.
Solution Approach 2:
The tanks are positioned asymmetrically around the column, with the supply tank on one side and recovery tank on the other. This asymmetric arrangement optimizes both capacity and accessibility, allowing components to be removed without interfering with each other.

AI summary
A surface cleaner (10) includes a main body (12), a base (14), and a column (18) extending from the base. A supply tank (42) extends around a first portion of the column. A first end of the supply tank is on a first side of the column. A second end of the supply tank is on a second side of the column. A recovery tank (46) extends around a second portion of the column. A first end of the recovery tank is on the first side of the column. A second end of the recovery tank is on the second side of the column. The first end of the supply tank is adjacent the first end of the recovery tank. The second end of the supply tank is spaced from the second end of the recovery tank. A battery (98) is coupled to the main body between the second ends of the supply and recovery tanks.
