Solution Overview

Problem

Conventional container cleaning devices struggle to achieve uniform cleaning due to non-uniform distances between the suctioning and supplying nozzles and the cuvette walls, leading to inefficiencies in cleaning liquid usage and potential carryover of sample residues.

Innovation Solution

A container cleaning device with a discharge section that conforms to the spherical inner bottom of the container, featuring a bottom portion with an aperture and channels that guide cleaning liquid to the aperture, and an elevator mechanism to ensure thorough cleaning with reduced liquid volume immersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If tubular suctioning nozzle and tubular supplying nozzle are inserted into squared tubular cuvette, then the sum of the volume of the submerged part of the supplying nozzle and the volume of the submerged part of the suctioning nozzle can be greater than the volume of the liquid within the cuvette, but the distance between the inner wall surface of the cuvette and the outer surface of the suctioning nozzle is not uniform in the cross section, preventing uniform cleaning

Engineering Contradiction:
Improveamount of cleaning liquidVSAvoiduniformity of cleaning
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The discharge section is designed with a spherical bottom surface that conforms to the spherical inner bottom of the container, replacing the tubular nozzle configuration. This curved geometry ensures uniform distance distribution between the discharge section outer surface and the container inner wall surface, enabling uniform cleaning while reducing the volume of cleaning liquid required.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Object-affected harmful factors

If cleaning is performed until the part at which the cleaning force is weakest is sufficiently clean, then carry over is reduced, but the total amount of cleaning liquid used cannot be reduced

Engineering Contradiction:
Improvecarry overVSAvoidtotal amount of cleaning liquid
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

By configuring the discharge section with a spherical bottom that matches the container's spherical inner bottom, the invention eliminates the greatest distance gap between the discharge section and container wall. This geometric conformity ensures that cleaning liquid reaches all surfaces uniformly, achieving thorough cleaning with reduced liquid volume and minimizing carry over without requiring excessive cleaning liquid.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Quantity of substance

If the discharge section is inserted to the deepest part of the container, then the volume of the submerged part of the discharge section is maximized, but the gap between the inner wall surface of the container and the bottom part of the discharge section becomes non-uniform

Engineering Contradiction:
Improvevolume of cleaning liquidVSAvoiduniformity of gap distribution
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The discharge section incorporates a spherical bottom surface that precisely conforms to the spherical inner bottom of the container. This geometric matching ensures that when the discharge section is inserted to the deepest part, the gap between its outer surface and the container inner wall remains uniform throughout, maximizing cleaning effectiveness while maintaining consistent liquid distribution.

Inventive Principle:
Principle #14Spheroidality (Curvature)
