Solution Overview

Problem

Container systems with press-and-turn and squeeze-and-turn closures face issues such as lost closures, difficulty in aligning threads for users with limited dexterity, and challenges in providing large openings while maintaining a compact and ergonomic closure mechanism.

Innovation Solution

A container system with a lid hingedly connected to a frame, featuring a first and second portion that are non-integrally connected, where the first portion can be moved from a first position to a second position to open the lid, and a rotatable dial with push pads that disengage the closure mechanism to allow access to the storage volume.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screw-off closure is used, then the container can be securely closed, but the closure may become separated from the container and get lost

Engineering Contradiction:

Improveclosure securityVSAvoidclosure retention

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The closure is merged with the container by hingedly connecting the lid to the container body, creating a unified structure where the closure cannot be lost. The lid remains attached to the container through the hinge mechanism while still allowing secure closure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lid is divided into a first portion (dial) and a second portion (cover), where the first portion is non-integrally connected to the second portion. This segmentation allows the lid to be moved from closed to open position while maintaining secure attachment to the container.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a screw-off closure is used, then the container can be securely closed, but aligning the threads can be challenging for users with limited manual dexterity

Engineering Contradiction:

Improveclosure securityVSAvoidthread alignment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The threading mechanism is extracted from the closure system and replaced with a hinge-connected lid structure. The lid connects to the container body through the hinge at the container opening, eliminating the need for thread alignment while maintaining secure closure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of having the closure screw onto the container opening, the lid is hingedly connected to the container body and moves to cover the opening. This inverts the traditional closure mechanism, making alignment unnecessary while maintaining security.

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If the container opening is made large for efficient filling, then filling efficiency improves, but the closure mechanism becomes harder to make compact and ergonomic

Engineering Contradiction:

Improvefilling efficiencyVSAvoidclosure compactness

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The lid is configured to extend beyond the periphery of the container opening when in the open position. This dimensional extension allows the lid to cover a large opening area while the hinge connection keeps the closure mechanism compact and ergonomic during operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
