Liquid Pump Dispenser With Adjustable Stop For Measured Liquor Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquor pourers lack the ability to provide a consistent and precise measurement of liquor, leading to inconsistencies in cocktail preparation, which can result in customer dissatisfaction and reduced profit margins due to over- or under-dispensing.
Innovation Solution
A liquid dispensing apparatus with a pumping mechanism, including a central body, liquid reservoir, draw tube, and adjustable pump shaft, designed to dispense a measured amount of liquor, specifically 0.5 to 2.0 US fluid ounces per operation, with interchangeable components for compatibility with various bottle sizes and customizable dispensing amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional liquor pourers or shot glasses are used for dispensing, then the device complexity is low and ease of operation is high, but the measurement precision and consistency of liquor dispensing deteriorate
Solution Approach 1:
The pump assembly is divided into separate interchangeable components including the pump body, pump shaft, seal assembly, and bottle cap assembly. This segmentation allows for modular manufacturing and assembly while maintaining precise dispensing measurements through standardized internal pump chamber dimensions.
Solution Approach 2:
The pump shaft incorporates an adjustable stop mechanism that can be positioned at different heights to control the dispensing volume. By changing the stop position parameter, the same pump body can dispense different precise volumes (e.g., 1 oz, 1.5 oz, 2 oz), maintaining measurement precision while adapting to various cocktail recipes.
2Measurement precision
If adjustable pump shaft with stop mechanism is used to control dispensing amount, then the measurement precision improves, but the ease of operation deteriorates
Solution Approach 1:
The pump shaft stop is pre-adjusted to the required height before use, and the pump assembly is pre-filled with liquor. The bartender simply needs to press the pump button a predetermined number of times to dispense the exact required amount, eliminating the need for manual measurement during operation.
Solution Approach 2:
The pump mechanism automatically dispenses the precise amount of liquor determined by the stop position without requiring the operator to measure or calculate. The mechanical stop self-regulates the dispensing volume, making the system self-correcting and easy to use.
3Adaptability or versatility
If generic one-size-fits-all liquor pourers are used, then the adaptability to different bottle types improves, but the measurement precision deteriorates
Solution Approach 1:
The pump assembly is designed with a universal bottle cap assembly that can accommodate different bottle sizes and shapes through adjustable sealing mechanisms. The same pump body can be used with various bottles while maintaining precise dispensing measurements through its controlled internal pump chamber and valve system.
Solution Approach 2:
The pump assembly acts as an intermediary device between the liquor bottle and the dispensing point. It decouples the bottle characteristics from the dispensing precision by using a standardized pump chamber that measures and dispenses accurate volumes regardless of the source bottle's variations.
4Ease of operation
If manual eyeballing or improper shot glass filling is used, then the ease of operation is high, but the loss of substance through spillage and inconsistency increases
Solution Approach 1:
The pump mechanism automatically controls the liquor flow and dispensing amount through its internal valve and stop mechanism. The system self-regulates to prevent overfilling and spillage, eliminating the need for the operator to judge when to stop pouring, thus preventing liquor loss while maintaining ease of operation.
