Lever-Action Dispensing Device with Adjustable Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operated dispensing assistance devices for aerosol and spray containers are limited in their ability to accommodate a wide variety of container sizes, shapes, and dispensing mechanisms, often requiring specific linear motion actions that restrict their usability with different types of containers.
Innovation Solution
A lever-action device with an adjustable receiver and linkage system that translates pivotable lever action into an arcuate motion, allowing the same device to effectively operate both aerosol and hand pump dispensing heads, with adjustable features for different container sizes and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated dispensing assistance device is designed for one specific type of container (e.g., aerosol or hand pump), then it can provide reliable and effective operation for that specific type, but it cannot accommodate a wide variety of different container sizes, shapes, and dispensing mechanisms
Solution Approach 1:
The device incorporates a universal mounting mechanism with adjustable clamps that can secure various container types and sizes. The linkage system is designed with adjustable arm lengths and pivot points, allowing the same device to adapt to different dispensing head positions and motion requirements, enabling one device to serve multiple container types effectively
Solution Approach 2:
The device uses adjustable and reconfigurable components including variable linkage lengths, adjustable pivot points, and flexible mounting positions. These dynamic adjustments allow the device to change its geometry and motion characteristics to match different container configurations while maintaining reliable operation
2Ease of operation
If a linear motion actuating mechanism is used for the spray nozzle, then the device can provide simple and direct force application, but it limits the device's ability to work with containers that require transverse or horizontal motion for dispensing
Solution Approach 1:
The device employs an arcuate motion path for the spray nozzle instead of linear motion. The linkage mechanism converts simple lever movement into curved trajectories that can accommodate both vertical push-down motions for aerosol cans and transverse/horizontal motions for pump spray bottles, providing versatility while maintaining ease of operation
Solution Approach 2:
The device adds a rotational dimension to the actuation mechanism, allowing the spray nozzle to move along an arc rather than only in a straight line. This dimensional change enables the same simple lever action to produce different motion directions (vertical, horizontal, or transverse) depending on the container type
3Ease of manufacture
If the device uses a fixed geometry design, then it can be manufactured simply and cost-effectively, but it cannot be adjusted to accommodate different container sizes, shapes, and dispensing head positions
Solution Approach 1:
The device is divided into modular segments including separate mounting components, adjustable linkage arms, and independent pivot points. Each segment can be manufactured using simple, cost-effective methods, while the modular assembly provides adjustability through standardized interfaces and configurable configurations

AI summary
An apparatus, method, and system that uses a lever action hand grip that can include an adjustable receiver for a variety of diameters, form factors, and other variables for different containers of liquids or aerosols that are desired to be dispensed. A linkage connects the lever action hand-grip to a working end. The working end moves in arcuate fashion in response to pivoting of the lever. The proportional working end motion path can serve to both push down an aerosol spray head to dispense, or laterally push or pump other types of dispensing heads. Optionally, the linkage can have at least one, and sometimes two or three, different adjustments for such things as size and location of a dispensing head for a variety of dispensing containers and types, range of motion, type of interface at the working end, and specifically what type of working end relative to a dispensing head of a container or bottle.
