Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal feed paint rollers require manual effort to move paint from the reservoir to the applicator head, which can be labor-intensive and inefficient.
Innovation Solution
A battery-powered paint applicator with an electric drive mechanism that includes a motor, pinion gear, and engagement mechanism to automate the movement of a piston within the reservoir, allowing for easy delivery of paint to the applicator head, with the option to manually operate in case of battery failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to move the piston in the reservoir, then the device complexity is reduced, but the ease of operation deteriorates due to labor-intensive effort
Solution Approach 1:
The patent replaces the manual mechanical operation of moving the piston with an electric motor-driven system. The motor converts electrical energy to mechanical motion, automatically actuating the piston to deliver paint from the reservoir to the applicator head, thereby reducing labor-intensive manual effort while managing the added complexity through integrated electrical components.
2Productivity
If an electric drive mechanism is added to automate piston movement, then the productivity is improved, but the device complexity increases due to additional motor and gear components
Solution Approach 1:
The manual mechanical system is replaced with an electric drive system comprising a motor and gear mechanism. This substitution automates the piston movement, significantly improving productivity by enabling continuous and consistent paint delivery without manual intervention, while the complexity is managed through compact integration of electrical components within the existing device structure.
3Reliability
If a gear engagement mechanism is implemented to control motor-piston interaction, then the reliability is improved by allowing manual operation fallback, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic engagement mechanism using gears that can selectively connect or disconnect the motor from the piston. This allows the system to switch between automated motor-driven operation and manual operation modes, enhancing reliability by providing a fallback option when batteries are unavailable or the motor fails, while managing complexity through a mechanically simple engagement interface.

AI summary
A hand-held, battery powered liquid applicator having an on-board reservoir. An electric motor drives a piston in the reservoir via a pinion gear member and rack gear. A gear shifter may disengage the pinion gear member from the rack gear. A battery compartment may have a door has recess to enable a user to grasp a dry cell located farthest from the door. The rack gear may have modified profile teeth at the end of travel to allow the pinion gear member to slip when the piston is urged past the end of travel. The piston may have a length substantially equal to a characteristic length of the reservoir. Liquid may be drawn into the reservoir by powered or manual retraction of the piston and liquid may be delivered from the reservoir to an applicator head by powered or manual motion of the piston into the reservoir.
