Solution Overview

Problem

Conventional containers with straws face inconveniences such as straw sinking or protruding, leading to contamination and usability issues when using lids.

Innovation Solution

A container assembly with a lid design that includes a sleeved portion and an annular pressing portion, allowing the straw to protrude into a secondary accommodating space without interfering with the lid, and maintaining a gap for easy access and sanitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the straw length is increased to prevent sinking, then the straw can be easily accessed, but the lid interferes with the protruding upper end

Engineering Contradiction:
Improvestraw accessibilityVSAvoidlid-straw interference
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lid is divided into multiple functional sections: a first accommodating space for the straw body, a second accommodating space for the protruding upper end, and a pressing portion that secures the straw. This segmentation allows the lid to accommodate different portions of the straw at different heights without interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lid structure extends vertically with multiple levels of accommodating spaces at different heights. The first accommodating space receives the lower portion of the straw, while the second accommodating space receives the upper protruding end, utilizing vertical dimensionality to resolve the interference problem.

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

2Device complexity

If the straw is stored outside the container, then the lid can close properly, but the straw becomes easily contaminated

Engineering Contradiction:
Improvelid closureVSAvoidstraw contamination
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The straw is nested within the lid structure itself. The lid contains accommodating spaces that hold the straw, effectively nesting the straw inside the lid-container assembly rather than outside the container. This prevents contamination while allowing proper lid closure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The lid acts as an intermediary structure between the container and the straw. It provides a protected environment with accommodating spaces that hold the straw, preventing direct exposure to external contamination sources while enabling lid closure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the straw is short, then it fits inside the container, but the entire straw sinks and requires finger grasping to remove

Engineering Contradiction:
Improvecontainer fitVSAvoidstraw removal
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The lid structure segments the straw accommodation into two parts: the first accommodating space for the main body and the second accommodating space for the upper end. This segmentation allows the straw to be properly positioned and accessed without sinking completely into the container.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressing portion is pre-configured to press against the straw and prevent it from sinking into the container body. This preliminary action maintains the straw in an accessible position, allowing easy removal without requiring finger grasping deep into the container.

Inventive Principle:
Principle #10Preliminary action

AI summary

A container assembly and a container lid are provided. The container assembly includes a container body, a lid, a sleeved portion, an annular pressing portion, and a straw. The container body has an opening portion at an upper end thereof. The lid is detachably disposed on the opening portion. The lid has an outer lid portion, an inner lid portion, and a connection portion, and the outer lid portion, the inner lid portion, and the connection portion jointly define a first heat insulation space. The connection portion has an annular abutting section, an enclosed end section, and an outer thread section arranged between the annular abutting section and the enclosed end section, and a distance between the enclosed end section and the annular abutting section is less than a distance between the enclosed end section and an inner lid top board of the inner lid portion.
