Solution Overview

Problem

Existing cap solutions for sealed packaging containers are impractical, often leading to spills when removed, and require manual handling, which can be cumbersome and expensive to manufacture, with issues of excessive opening size and user safety concerns.

Innovation Solution

A cap with a perforation platform that moves vertically from a resting to a working position, using articulated arms to maintain parallel alignment with the container surface, allowing controlled perforation without rotation, thus preventing leaks and simplifying handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cap is removed from the container, then the liquid can be accessed, but the liquid may get spilt

Engineering Contradiction:

Improveaccess to liquidVSAvoidspilling

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cap is divided into a stationary body and a movable perforation platform. The platform can be independently actuated to create openings without moving the entire cap, allowing controlled access to liquid while maintaining cap stability on the container.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movable perforation platform acts as an intermediary between the user and the liquid. It provides a controlled interface for accessing the liquid through perforations, preventing direct contact with the bulk liquid and thus reducing spill risk.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If accessories are added to perforate the container, then drinking is facilitated, but manual handling becomes cumbersome

Engineering Contradiction:

Improvedrinking facilitationVSAvoidmanual handling

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The perforation platform is integrated into the cap structure itself, combining the cap function with the perforation function. This eliminates the need for separate accessories and reduces manual handling complexity while maintaining drinking facilitation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cap structure includes built-in mechanisms (movable platform with perforating elements) that automatically perform the perforation function when activated, eliminating the need for external accessories and simplifying user interaction.

Inventive Principle:

Principle #25Self-service

3Reliability

If the cap is perfectly centred on the container, then pivoting action is effective, but gaps should not exist

Engineering Contradiction:

Improvepivoting effectivenessVSAvoidcentering precision

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The pivoting function is extracted from the cap-body connection and relocated to the connection between the movable platform and the cap body. This allows the main cap to remain stably centered on the container while the movable platform handles the pivoting action independently.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The connection between the movable platform and cap body is designed to be dynamic, allowing pivoting motion. This dynamic connection enables effective pivoting action without requiring the entire cap to be perfectly centered, as only the movable platform needs pivoting capability.

Inventive Principle:

Principle #15Dynamics

4Productivity

If the flange rotates on a large angle, then perforation is achieved, but user's finger may end up inside

Engineering Contradiction:

Improveperforation achievementVSAvoidfinger injury

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The perforation platform uses multiple perforating elements that create openings with partial rotation (less than 30 degrees). This partial action is sufficient to achieve effective perforation while minimizing the rotation angle, thereby preventing finger injury.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The perforating elements are designed as disposable or single-use features on the movable platform. After perforation, the platform can be discarded or reset, eliminating the need for large-angle rotations that could endanger the user.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

This invention proposes a cap (2) for a container (1) which has an upper surface (10), wherein the cap (2) includes a body configured to attach to the upper surface of the container, and a perforation platform (3) comprising a plurality of protruding perforating elements (4a, 4b), so that the perforation platform (3) is displaced vertically with respect to the body from a resting position to a working position, and wherein the perforating elements (4a, 4b) perforate an upper lid of the container. In the resting position, the perforation platform (3) is horizontally aligned with the upper surface (2a) of the body of the cap (2), while, in the working position, the perforation platform is displaced vertically, and in its entirety, a distance so that the protruding perforating elements (4a,4b) exclusively penetrate the upper surface (10) of the container (1) and the perforation platform (3) remaining in a parallel position to the upper surface (2a) of the cap (2).
