Solution Overview

Problem

Existing dosing systems in bottles suffer from measurement inaccuracy, contamination, and difficulty in reading measuring scales, leading to potential waste and increased user expense.

Innovation Solution

A dosing bottle arrangement featuring a container with a protruding neck, a cap piece with a gusset and standpipe, and a rotatable closure member that allows for precise liquid dosing through adjustable return openings and visual markings, enabling accurate and contamination-free dosing without direct contact with the liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a measuring scale is marked on the inside of the dosing cap, then dosing measurement is enabled, but measurement inaccuracy and difficulty in reading the measuring scale occur

Engineering Contradiction:
Improvedosing measurement accuracyVSAvoiddifficulty in reading measuring scale
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent replaces the traditional measuring scale marked on the cap with a visual copying system. Visual indicators on the cap correspond to specific dosing volumes, allowing users to read the measurement externally rather than searching for markings inside the cap. This external visual copy of the dosing information eliminates reading difficulties while maintaining measurement accuracy.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces visual indicators as an intermediary between the liquid volume and the user. Instead of directly reading markings inside the cap, users observe the position of visual indicators that represent dosing volumes, making the measurement process clearer and more accurate without direct contact with the liquid.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the measuring chamber is reused, then the dosing device can be used multiple times, but contamination by product residue occurs

Engineering Contradiction:
Improvereusability of dosing deviceVSAvoidcontamination by product residue
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the measurement function from the liquid-contacting chamber. By using visual indicators that show dosing volumes without requiring the user to read markings inside the cap, the system eliminates the contamination risk associated with reusing the measuring chamber. The user can remove and clean the chamber while retaining the reusable cap with visual indicators.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the dosing device into separate functional components: the liquid-contacting chamber that can be removed and cleaned, and the cap with visual indicators that remains reusable. This segmentation allows the chamber to be sanitized without affecting the reusable dosing mechanism, eliminating contamination issues while maintaining versatility.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If product is wasted due to inaccurate dosing, then the dosing device loses precision, but user expense increases

Engineering Contradiction:
Improvedosing precisionVSAvoidproduct waste
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent uses visual indicators that accurately copy and represent specific dosing volumes. These visual markers allow users to precisely measure and transfer the intended amount of liquid, eliminating the guesswork and inaccuracy that lead to product waste. The visual copy system ensures consistent, precise dosing that prevents both under-dosing and over-dosing.

Inventive Principle:
Principle #26Copying

AI summary

A dosing bottle has a container; a riser; a cap piece; a standpipe connected to the riser and one or more return openings in a tubular wall of the standpipe; and a closure member. The closure member is rotatably attached to the cap piece and defines an interior dosing volume and a dispenser opening. The closure member is axially movable relative to the cap piece between a closed position and an open position. The open position allows a liquid in the interior volume of the container to flow through the riser and through the return opening and into the interior dosing volume.
