Solution Overview
Problem
Conventional sprayer dispensers are limited in their ability to adjust dispensing characteristics, require excessive force for actuation, and are not optimized for various compositions, leading to inefficiencies and environmental waste due to mixed materials.
Innovation Solution
A powered refillable sprayer dispenser with a 360° rotational pump assembly, variable pressure diaphragm or gear pump, and a motor-actuated nozzle that maintains fluid communication throughout rotation, allowing for adjustable particle size distribution and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sprayer dispensers are designed generically to dispense a myriad of fluids, then mass production and wide range of dispensing purposes are achieved, but the ability to adjust dispensing characteristics is very limited
Solution Approach 1:
The patent implements a rotatable pump assembly that can be positioned at different angles (0°, 45°, 90°, 135°) relative to the container wall, allowing dynamic adjustment of spray direction and characteristics. This mechanical dynamic configuration enables a single device to adapt to multiple dispensing scenarios without requiring multiple specialized devices.
2Strength
If conventional sprayers require greater force to actuate the trigger, then structural strength is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the conventional manual trigger mechanism with a motor-driven actuator system. The motor (126) mechanically engages with the pump assembly (120) to drive fluid dispensing, eliminating the need for high manual force on the trigger. The user simply activates a low-force trigger (104) that signals the motor to perform the work, significantly reducing actuation force requirements.
3Ease of operation
If conventional powered spray dispensers rely on traditional dip tubes to feed fluid to the pump, then simple fluid delivery is achieved, but the directional range consumers can dispense the product effectively and evenly is restricted
Solution Approach 1:
The pump assembly (120) is designed to rotate relative to the container wall, allowing it to be positioned at multiple angles (0°, 45°, 90°, 135°). This dynamic positioning capability enables the pump to draw fluid from different locations along the container wall and dispense product in various directions, greatly expanding the effective directional range compared to fixed dip tube configurations.
4Ease of operation
If conventional sprayers require coupling between human hand mechanical engagement and actuation, then mechanical control is achieved, but muscle tiring and limitations of human mechanics compromise the adjustments
Solution Approach 1:
The patent automates the fluid dispensing mechanism by replacing manual pump operation with an electric motor (126). The motor is mechanically coupled to the pump assembly (120) and can be activated by a simple trigger press or wave motion detection, eliminating the need for continuous manual pumping or triggering. This automation reduces muscle tiring and overcomes human mechanical limitations while maintaining precise control over dispensing.

AI summary
A spray dispenser container includes a housing having a first end portion, a second end portion, a sidewall extending between the first end portion and the second end portion, and a cavity at least partially surrounded by the sidewall; a pump assembly in fluid communication with a replaceable composition container including a composition, the pump assembly being disposed within the cavity; an actuator in operative communication with the pump assembly; a nozzle in fluid communication with the pump assembly; and a motor in operative communication with the actuator. Furthermore, when the spray dispenser container is rotated 360° along the vertical plane, the pump assembly maintains fluid communication with the replaceable composition container such that the composition can be dispensed throughout the 360° rotation.
