Solution Overview

Problem

Existing bottle cap designs fail to prevent substances from dripping down the sides of bottles during pouring, leading to sticky bottles and surfaces.

Innovation Solution

A bottle cap drip tray device with an upstanding inner wall, an upturned peripheral edge, and a floor portion that forms a drip tray to catch and contain substances, preventing them from dripping down the bottle sides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional bottle cap design is used, then the bottle is simple and easy to manufacture, but substances drip down the sides of the bottle during pouring

Engineering Contradiction:
Improvesubstance drippingVSAvoidbottle cap structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The bottle cap is divided into multiple functional segments: a cap body for sealing, a drip tray component with upstanding inner wall and upturned peripheral edge for catching drips, and a floor portion for containing substances. This segmentation allows each part to perform its specific function while collectively preventing substance from dripping down the bottle sides.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The drip tray component extends radially outward from the bottle cap with an upturned peripheral edge that forms a rim, creating a three-dimensional containment structure. This dimensional extension allows the drip tray to catch and contain substances that would otherwise drip down the bottle sides, adding a new spatial dimension to the traditional flat cap design.

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

2Object-affected harmful factors

If a bottle cap drip tray device is added to prevent dripping, then substance dripping is prevented, but the device complexity increases

Engineering Contradiction:
Improvesubstance drippingVSAvoidbottle cap structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The drip tray component is merged with the bottle cap to form an integrated assembly. The cap body and drip tray component are connected such that they function together as a single unit, eliminating the need for separate drip-traying devices and reducing overall system complexity while maintaining the anti-drip function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bottle cap assembly serves multiple functions: the cap body provides sealing and dispensing, while the integrated drip tray component simultaneously catches drips, contains substances, and prevents them from reaching the bottle sides. This multi-functionality reduces the need for additional separate components.

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

3Object-affected harmful factors

If the upturned peripheral edge has a varying slope, then substance containment is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvesubstance containmentVSAvoidcurved surface geometry
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The upturned peripheral edge is designed with curved upper and lower surfaces that slope gradually from the floor portion outward to the outer peripheral boundary. This curvature allows substances to be guided smoothly along the contoured surface toward the outer edge, improving containment effectiveness while the gradual slope transitions make the geometry more amenable to standard manufacturing processes.

Inventive Principle:
Principle #14Spheroidality (Curvature)
