Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PET bottles generate significant waste due to non-degradability, while biodegradable alternatives like paper bottles lack structural strength and integrity, and existing solutions fail to meet stringent recycling and environmental compliance requirements.
Innovation Solution
A fully recyclable container composed of biodegradable components, including a cap, shoulder, body, and base made of biodegradable plastic, with a spiral paper tube body and a liner formed by blow molding, connected using locking members and threads, allowing easy assembly and disassembly for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If paper-based bottles are used to replace PET bottles, then environmental degradability is improved, but structural strength and crush strength become insufficient
Solution Approach 1:
The invention uses a composite structure combining biodegradable plastic components (cap, shoulder, base, liner) with a paper tube body. This composite approach allows the container to achieve both environmental degradability and sufficient structural strength, as each material contributes its advantageous properties while working together as an integrated system.
Solution Approach 2:
The container is divided into multiple detachable components (cap, shoulder, body, base, liner) that can be separately manufactured and assembled. This segmentation allows optimization of each component's material properties - using biodegradable plastics for strength-critical parts and paper for the body - while maintaining overall structural integrity and environmental friendliness.
2Ease of manufacture
If integrally formed paper-based bottles are used, then production ease is improved, but structural strength becomes insufficient
Solution Approach 1:
The container is divided into multiple detachable components (cap, shoulder, body, base, liner) that can be separately manufactured and assembled. This segmentation allows optimization of each component's material properties - using biodegradable plastics for strength-critical parts and paper for the body - while maintaining overall structural integrity and environmental friendliness.
3Strength
If conventional PET bottles are used, then structural strength is maintained, but environmental waste problems worsen
Solution Approach 1:
The invention uses a composite structure combining biodegradable plastic components (cap, shoulder, base, liner) with a paper tube body. This composite approach allows the container to achieve both environmental degradability and sufficient structural strength, as each material contributes its advantageous properties while working together as an integrated system.
Solution Approach 2:
The invention changes the material parameters from conventional non-biodegradable PET to biodegradable plastics and paper materials. This parameter change in material composition maintains structural strength through proper design while fundamentally altering the environmental degradation characteristics to be eco-friendly.
4Object-affected harmful factors
If biodegradable plastic components are used instead of conventional materials, then recyclability is improved, but manufacturing complexity increases
Solution Approach 1:
The container is divided into multiple detachable components (cap, shoulder, body, base, liner) that can be separately manufactured and assembled. This segmentation allows optimization of each component's material properties and simplifies recycling processes, as each component can be independently processed according to its material type.
Solution Approach 2:
The design incorporates detachable connections and locking members that enable easy disassembly before recycling. This preliminary design consideration for disassembly simplifies the subsequent recycling process, allowing components to be quickly separated and sorted without complex processing.
Applied Scientific Principles

AI summary
In a fully recyclable container and a method of manufacturing the same the container includes a cap, a shoulder, a body, a base, and a liner. The cap, the shoulder, and the base are made of biodegradable plastic by injection molding while the body is made of waterproof paper. The cap, the shoulder, and the base are detachably connected to form a housing of the container. The liner is formed inside the housing by blow molding of biodegradable plastic. The respective components of the container are completely made of biodegradable or bio-decomposable material and able to be disassembled for sorting and recycling. Thereby the fully recyclable container completely meets requirements of environmental protection and recycling.
