Solution Overview

Problem

Current packaging materials face challenges in maintaining protective functionality while being environmentally friendly, as they often rely on non-recyclable and non-biodegradable materials like plastics, and struggle to provide both rigidity and cushioning effectively during transit.

Innovation Solution

The development of variably-compressed fiber-based packaging components formed through a dry molding process, which incorporates high-compressed and low-compressed regions within a unitary body, utilizing plant-based fibers to create a recyclable and customizable packaging solution that can provide both structural rigidity and cushioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional plastic packaging materials are used, then protective functionality and structural integrity are maintained, but environmental friendliness and recyclability deteriorate

Engineering Contradiction:

Improveprotective functionalityVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by varying the compression density of fiber materials across different regions of the packaging structure. High-density compressed regions provide structural integrity and rigidity for protection, while low-density uncompressed regions provide cushioning and environmental friendliness. This spatial variation in density parameters resolves the contradiction between protective functionality and environmental impact.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by combining fiber materials with different compression levels (high-density and low-density regions) within a single packaging structure. This composite approach allows different regions to perform different functions - high-density areas provide structural support while low-density areas provide cushioning - thereby maintaining protective functionality while using environmentally friendly fiber materials instead of plastics.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If uniformly compressed fiber packaging is used, then manufacturing simplicity is maintained, but functional performance (simultaneous rigidity and cushioning) deteriorates

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidfunctional performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent applies local quality by creating regions with different compression densities within the same packaging structure. High-compression regions provide rigidity and structural support, while low-compression regions provide cushioning and shock absorption. This local differentiation of material properties enables the packaging to perform multiple functions simultaneously without complicating the manufacturing process, as all regions are formed from the same fiber material through controlled compression variations.

Inventive Principle:

Principle #3Local quality

3Strength

If high-density compressed regions are used throughout, then structural rigidity is improved, but cushioning capability deteriorates

Engineering Contradiction:

Improvestructural rigidityVSAvoidproduct protection during transit

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent resolves this contradiction by applying local quality - creating high-density compressed regions for structural rigidity in areas requiring support, and low-density uncompressed regions for cushioning in areas requiring shock absorption. This spatial differentiation allows the packaging to provide both rigidity and cushioning simultaneously, protecting products during transit while maintaining structural integrity.

Inventive Principle:

Principle #3Local quality
