Solution Overview

Problem

Conventional blister packaging is difficult to open, costly due to excessive material usage, and often fails to protect abrasive or sharp product elements, posing risks to consumers and other products.

Innovation Solution

A clear plastic packaging device with a depressed compartment and lateral wings for securing the product, featuring a folding hanger for display support and easy opening, constructed from flexible materials like PET or PVC to minimize weight and cost while effectively shielding sharp or abrasive elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional blister packaging is used to cover the entire product, then the abrasive or sharp elements are protected, but the manufacturing cost and shipping cost significantly increase

Engineering Contradiction:
Improveprotection of abrasive or sharp elementsVSAvoidamount of plastic material
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The packaging device divides the protective function into segments: only the critical abrasive or sharp elements are enclosed in a plastic blister compartment, while the rest of the product remains exposed. This segmented approach reduces plastic material usage while maintaining necessary protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The packaging applies protection locally only where needed - the blister compartment is positioned specifically over the abrasive or sharp elements, providing targeted protection rather than universal coverage. This local quality approach minimizes material consumption while achieving the protective function.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If relatively hard plastic is used for blister packaging, then the packaging provides adequate protection, but the packaging becomes difficult to open requiring sharp blades or scissors

Engineering Contradiction:
Improveprotection effectivenessVSAvoidease of opening
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The packaging incorporates a perforated opening line that transforms the static hard plastic structure into a dynamically openable system. The perforations create a controlled weakness that allows the consumer to easily tear open the packaging by hand, while the intact plastic remains sufficiently hard to provide protection during normal handling and display.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If the entire product is covered with blister packaging, then complete protection is achieved, but the overall volume of the product increases

Engineering Contradiction:
Improvecomplete protectionVSAvoidoverall product volume
Core Design Contradiction:
Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The packaging encloses only the specific abrasive or sharp elements that require protection, rather than covering the entire product. This segmented enclosure approach minimizes the volume added by packaging while ensuring that the critical protective function is maintained for the exposed elements.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If thin flexible plastic is used for blister packaging, then the packaging is easy to open and cost-effective, but the protection of abrasive or sharp elements is insufficient

Engineering Contradiction:
Improveease of openingVSAvoidprotection of abrasive elements
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The packaging uses a thin flexible plastic blister compartment that is sufficiently thick to protect sharp or abrasive elements during normal handling, yet thin enough to be easily torn open along the perforated line. The flexible nature of the thin plastic allows it to conform to the product while maintaining protective capabilities.

Inventive Principle:
Principle #30Flexible shells and thin films
