Solution Overview

Problem

Conventional fluid dispensing devices typically discharge fluid in a single direction, requiring user contortion and rotation to cover large areas, such as a toilet bowl, as they lack the ability to simultaneously direct fluid in multiple directions.

Innovation Solution

A fluid dispensing device with a closure body and a deflector surface that generates a spray pattern extending at a deflection angle, allowing fluid to be directed in multiple directions simultaneously by using a rotatable deflector disc or multiple orifices with deflector surfaces, enabling efficient coverage without user contortion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a single discharge outlet is used to avoid spraying product onto the user, then user safety is improved, but the ability to cover large areas efficiently deteriorates

Engineering Contradiction:
Improvespray onto userVSAvoidcoverage efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The single discharge outlet is segmented into multiple discharge outlets (first, second, third outlets) arranged in different directions. This allows the fluid to be discharged simultaneously in multiple directions, covering large areas efficiently while preventing spray from reaching the user's hand and arm.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The discharge outlets are arranged in three-dimensional space at different angles and orientations. The first outlet discharges along the cap axis, the second outlet discharges at an angle, and the third outlet provides additional directional coverage, creating a multi-dimensional spray distribution pattern.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If multiple discharge outlets are provided, then coverage area is improved, but device complexity increases

Engineering Contradiction:
Improvecoverage areaVSAvoidoutlet structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The cap assembly serves multiple functions: it acts as a closure, a dispensing mechanism, and a directional control device. The same cap structure that closes the container also houses multiple discharge outlets and controls fluid flow through its positioning relative to the container opening.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple discharge outlets are integrated into a single cap assembly rather than being separate components. The cap combines multiple outlet functions, control mechanisms, and structural support into one unified component that attaches to the container.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a single direction discharge is used, then device simplicity is maintained, but user ergonomics deteriorate

Engineering Contradiction:
Improvedispenser structureVSAvoiduser positioning
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The single discharge direction is segmented into multiple discharge directions (first, second, third outlets at different angles). This eliminates the need for users to rotate their hand and arm to cover different areas, as the multi-directional outlets provide comprehensive coverage from a single stationary position.

Inventive Principle:
Principle #1Segmentation

4Speed

If the cap is always open for dispensing, then dispensing speed is improved, but fluid loss increases

Engineering Contradiction:
Improvedispensing speedVSAvoidfluid loss
Core Design Contradiction:
SpeedVSLoss of substance

Solution Approach 1:

The cap is designed to be periodically opened and closed based on dispensing needs. The cap can be rotated to an open position for rapid dispensing when coverage is needed, then closed to prevent evaporation and fluid loss when dispensing is complete, creating a periodic open-closed cycle.

Inventive Principle:
Principle #19Periodic action

AI summary

A fluid dispensing device is provided that is capable of discharging fluid in multiple different directions simultaneously. The device may include a deflector which redirects an initial stream of fluid from the container into multiple sub-streams that are oriented in different directions. The device may create a spray pattern that substantially covers an entire 360 degree area surrounding the device, which may be advantageous for certain applications such as toilet bowl cleaner dispensers. A control valve or flow restrictor may be provided for preventing unintended discharge of fluid when the container is inverted.
