Solution Overview

Problem

Existing containers, particularly lightweight plastic bottles, suffer from deformation due to internal vacuums caused by oxygen absorption, which affects aesthetic appeal and structural integrity under varying environmental conditions.

Innovation Solution

The containers incorporate pillars and dynamic panels that allow controlled deformation under vacuum pressure, maintaining structural integrity while reducing internal vacuum levels by accommodating increased pressure.

1Weight of moving object

If lightweight container walls are used to reduce weight, then material usage and weight decrease, but vacuum resistance and structural integrity deteriorate

Engineering Contradiction:

Improvecontainer weightVSAvoidvacuum resistance

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The container body is segmented into multiple panels separated by corner pillars, creating a structured framework that distributes vacuum loads across discrete structural elements rather than relying on continuous wall thickness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the container have different structural properties - corner pillars provide rigid support at critical stress points while panel areas between pillars are designed to deform controllably, creating local variations in stiffness and strength

Inventive Principle:

Principle #3Local quality

Core Design Contradiction:

Solution Approach 1:

The panel regions are designed with dynamic deformation characteristics that allow them to flex and accommodate vacuum pressure changes, transitioning from a purely rigid structure to a semi-flexible system that manages stress through controlled movement

Inventive Principle:

Solution Approach 2:

The corner pillars are positioned in advance at critical locations to provide structural support before vacuum deformation occurs, preventing catastrophic failure while using minimal material

Inventive Principle:

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

By dividing the container into discrete panels and pillars, the deformation is localized to specific panel regions rather than affecting the entire container, allowing aesthetic design in pillar regions while accommodating deformation in panel areas

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The corner pillars create an asymmetric structural framework that provides strength while allowing the panel areas between them to deform in a controlled, aesthetically manageable manner

Inventive Principle:

Solution Approach 1:

The corner pillars provide localized structural support at critical load-bearing points, eliminating the need for uniformly thick walls throughout the entire container while maintaining top load compression resistance

Inventive Principle:

Solution Approach 2:

The container structure is divided into load-bearing pillar elements and non-load-bearing panel areas, allowing material to be concentrated where structurally necessary and reduced where it provides minimal benefit

AI summary

A container includes a body, the body has pillars, and the body also has dynamic panels. The pillars include first, second, third and fourth pillars, and each of the first, second, third and fourth pillars is substantially rounded outward relative to a vertical axis of the container. The dynamic panels include first, second, third and fourth dynamic panels. The first dynamic panel extends between the first pillar and the second pillar, is substantially parallel to the third dynamic panel, and is substantially perpendicular to each of the second and fourth dynamic panels, such that the pillars are positioned at corners of the container. Each of the first, second, third and fourth pillars has greater stiffness than each of the first, second, third and fourth dynamic panels and thereby provide a controlled deformation of the container under vacuum pressure or top loading.
