Solution Overview

Problem

The use of petroleum-derived synthetic resins in gift-set trays leads to environmental pollution and resource exhaustion due to their non-recyclable nature and inability to create unique textures.

Innovation Solution

A sheet and gift-set tray made using rice bran and inorganic fillers, which reduces the use of synthetic resins by incorporating a rice bran composition with synthetic resin, inorganic filler, and additives, providing a new texture and scent while being environmentally friendly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If synthetic resins are used to manufacture gift-set trays, then processability, flexibility, intensity and low price are improved, but environmental pollution and resource exhaustion worsen

Engineering Contradiction:
ImproveprocessabilityVSAvoidenvironmental pollution
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent uses composite materials by combining synthetic resin with rice bran and inorganic filler to create a new material system. This composite approach allows the retention of synthetic resin's processability while incorporating natural substances that reduce environmental pollution and enable recycling, directly resolving the contradiction between ease of manufacture and environmental harm

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the compositional parameters of the material by incorporating 20-80 wt% rice bran and 0-60 wt% inorganic filler into the synthetic resin matrix. This parameter change transforms the material properties to achieve both good processability and environmental friendliness, resolving the contradiction between manufacturing ease and environmental pollution

Inventive Principle:
Principle #35Parameter changes

2Strength

If synthetic resins are used to manufacture gift-set trays, then flexibility and intensity are improved, but recyclability worsens

Engineering Contradiction:
ImproveintensityVSAvoidrecycling difficulty
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent creates a composite material system combining synthetic resin with rice bran and inorganic filler. This composite structure maintains the intensity and flexibility provided by synthetic resin while the natural components (rice bran) enable easier separation and recycling, resolving the contradiction between strength and recyclability

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent segments the material into distinct components (synthetic resin matrix, rice bran particles, inorganic filler) that can be separately processed during recycling. This segmentation allows the synthetic resin to provide structural strength while the natural components can be easily separated and recycled, resolving the recycling difficulty

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If rice bran is added to reduce synthetic resin content, then environmental friendliness and cost are improved, but material strength may worsen

Engineering Contradiction:
Improveenvironmental friendlinessVSAvoidmaterial strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent uses composite materials where rice bran (20-80 wt%) provides environmental friendliness and cost reduction, while inorganic filler (0-60 wt%) compensates for potential strength loss. The synthetic resin matrix binds these components together, maintaining adequate material strength while achieving environmental benefits

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies local quality by assigning different functional roles to different components: synthetic resin provides structural strength and binding, rice bran provides environmental friendliness and cost reduction, while inorganic filler provides additional structural support. This functional distribution resolves the contradiction between environmental friendliness and material strength

Inventive Principle:
Principle #3Local quality

AI summary

The present design relates to an advantageous and useful sheet which contains rice bran and to a gift-set tray made with the same, wherein the sheet comprises: a substrate layer (10); and a rice-bran-containing layer (20) formed on at least one surface of the substrate layer (10), wherein the rice-bran-containing layer (20) consists of a rice-bran-containing composition comprising a synthetic resin and rice bran as well as an inorganic filler and an additive, such that the use of rice bran and inorganic filler provide a rice-bran foaming effect during extrusion of the sheets for gift-set trays, which makes it possible to reduce the synthetic resin content and prevent depletion of petroleum resources and reduce environmental pollution, while lowering production costs by addition of the rice bran, and provide unique texture and aroma which are not possible with synthetic resins, and the use of the rice bran sheets provides environmentally friendly gift-set trays.
