Solution Overview

Problem

Existing methods for manufacturing blow-molded containers often require post-molding attachment of lid elements, which can be inefficient and environmentally unfriendly, especially when shipping partially or fully blown containers without lids.

Innovation Solution

A preform with a lid element attached before blow molding, using techniques such as ultrasonic welding, laser welding, or gluing, to create a container with the lid integrated during the molding process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If lid elements are attached after blow molding, then the container can be manufactured with separate components, but the manufacturing process becomes more complex and time-consuming

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidprocess complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the lid element attachment process with the blow molding process into a single integrated operation. The preform is designed with an integrated structure that allows the lid element to be attached during blow molding, eliminating the need for separate post-molding attachment steps and reducing overall process complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent prepares the preform with pre-positioned attachment features or integrated lid structures before the blow molding process begins. This preliminary preparation enables the lid element to be attached during the blow molding operation itself, rather than requiring separate post-processing steps

Inventive Principle:

Principle #10Preliminary action

2Productivity

If lid elements are attached after blow molding, then shipping can be simplified, but environmental impact increases due to shipping empty containers

Engineering Contradiction:

Improveshipping efficiencyVSAvoidenvironmental impact

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent merges the container and lid element into a single integrated unit before shipping by attaching the lid during the blow molding process. This eliminates the need to ship separate empty containers and lid elements, reducing overall shipping volume and environmental impact while maintaining shipping efficiency

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If lid elements are attached after blow molding, then storage requirements are reduced, but separate lid storage and handling is required

Engineering Contradiction:

Improvestorage requirementsVSAvoidhandling complexity

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent combines the lid element with the container body during the blow molding process, creating a single integrated product. This eliminates the need for separate storage facilities and handling procedures for lid elements, reducing both storage requirements and handling complexity simultaneously

Inventive Principle:

Principle #5Merging (Combining)
