Solution Overview

Problem

Existing food and beverage packaging lids made of plastic for indicating contents are environmentally unsustainable and often illegible, posing challenges in identifying contents without manual labeling, which can lead to contamination and inconvenience.

Innovation Solution

A lid composed of paperboard and/or cardboard material with flaps that can be moved to indicate contents, featuring product-specific indications and a breakable connection to ensure visibility without plastic use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If plastic lids with pressable indications are used, then product identification is enabled, but environmental sustainability deteriorates

Engineering Contradiction:
Improveproduct identificationVSAvoidenvironmental impact of plastic
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to paperboard/cardboard, transforming the lid from a non-biodegradable to a biodegradable material while maintaining the product indication functionality through the same flap mechanism

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The lid is constructed as a composite structure with an outer layer (paperboard/cardboard) and an inner layer (plastic or paperboard), combining the environmental benefits of paperboard with the functional requirements of the container closure

Inventive Principle:
Principle #40Composite materials

2Loss of information

If handwriting is used to label container contents, then product identification is achieved, but legibility and hygiene deteriorate

Engineering Contradiction:
Improveproduct identificationVSAvoidlegibility and hygiene
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The product indication is pre-printed on the lid during manufacturing, eliminating the need for manual writing and ensuring consistent, legible labeling while avoiding hygiene issues associated with handwriting

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The lid serves as a template or copy that contains pre-printed product information, replacing the need for direct manual labeling and ensuring accurate, readable content without contact with permanent markers

Inventive Principle:
Principle #26Copying

3Loss of information

If flaps are made movable to indicate contents, then product visibility is improved, but device complexity increases

Engineering Contradiction:
Improveproduct visibilityVSAvoidlid structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The lid is divided into functional segments: an outer layer with movable flaps for indication and an inner layer for structural support and sealing, allowing the indication function to be separated from the closure function

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flaps are designed to be movable rather than fixed, transitioning between closed and open positions to reveal product information, adding dynamic functionality while maintaining overall structural simplicity

Inventive Principle:
Principle #15Dynamics
