Solution Overview

Problem

Conventional sports bottles require manual squeezing to pour fluid and lack spill protection, making it inconvenient and prone to spills during activities like walking, biking, or running.

Innovation Solution

A pour cap with a cap body, gasket, and threaded ring that allows fluid to be poured without removing the cap, featuring elliptical pour openings, grip segments, and a gasket for sealing and fluid flow control, enabling easy drinking without spills.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cap is removed from a conventional sports bottle, then the fluid can be poured out of the bottle, but the fluid is more likely to spill out of the bottle and onto the ground

Engineering Contradiction:
Improvepouring convenienceVSAvoidspill protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cap is segmented into functional zones: a pour opening for fluid dispensing, a seal engagement region for spill prevention, and a valve assembly interface. This segmentation allows the cap to provide both pouring convenience and spill protection simultaneously by directing fluid flow through controlled pathways while maintaining sealing at critical interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cap acts as an intermediary component between the bottle interior and exterior environment. It mediates fluid flow by providing a controlled pour opening while preventing uncontrolled spillage through its sealing surfaces that engage with the bottle neck, thus resolving the contradiction between easy pouring and spill protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the cap is removed from a conventional sports bottle, then the fluid can be poured out of the bottle, but the fluid is prone to splatter onto a person's face and clothes

Engineering Contradiction:
Improvepouring convenienceVSAvoidfluid splatter
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cap incorporates local quality variations through its geometry: the pour opening is positioned and sized to control fluid flow direction, while the rim structure provides a lip that contains splatter. This localized structural quality ensures fluid flows smoothly for convenient pouring while preventing splatter from reaching the user's face and clothes.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a conventional sports bottle uses a valve assembly, then the fluid can be dispensed, but the bottle must be squeezed and manipulated to allow air flow and maintain fluid flow

Engineering Contradiction:
Improvefluid dispensingVSAvoidbottle manipulation
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pouring function is extracted from the bottle body and concentrated in the cap assembly. The cap includes a pour opening and structural features that enable gravity-assisted pouring without requiring bottle squeezing or complex manipulation, thus simplifying the overall device operation while maintaining fluid dispensing capability.

Inventive Principle:
Principle #2Taking out (Extraction)
