Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The timber pallet and crate industry faces challenges due to the lack of a single international standard, leading to excessive waste and environmental concerns, as well as the need for invasive species and disease prevention treatments that hinder re-use and disposal of timber pallets.
Innovation Solution
A fused solid material comprising a starch and plasticizer matrix with continuous fibre under tension, which is biodegradable and suitable for producing pallets and crates, reducing waste and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timber pallets are treated with chemical fumigation or heat treatment to prevent invasive species, then compliance with international standards is improved, but the re-use and disposal of pallets becomes more difficult
Solution Approach 1:
The invention changes the fundamental material parameter from natural timber to a synthetic biodegradable polymer composite. This allows the material to inherently meet IPPC standards without requiring additional treatment while maintaining full biodegradability and re-usability, thus resolving the contradiction between compliance and ease of manufacture
Solution Approach 2:
The invention uses a composite material system consisting of biodegradable polymer matrix combined with natural fibers (such as hemp, jute, or sisal). This composite provides both the structural integrity needed for pallet applications and the biodegradability required for easy disposal, while the synthetic nature eliminates invasive species concerns
2Loss of substance
If a single international standard for pallet size and shape is implemented, then waste from pallet transfers is reduced, but the ability to satisfy diverse country-specific needs is limited
Solution Approach 1:
The invention segments the pallet standardization problem by allowing the base pallet design to follow international standards while enabling easy modification through the addition of attachments, extensions, or modifications that can be made from the same biodegradable material. This allows a standardized core design to be adapted to various country-specific requirements without creating waste
Solution Approach 2:
The biodegradable polymer composite material provides universal applicability across different pallet designs and specifications. The material can be molded into various shapes and sizes to meet different country-specific requirements while maintaining consistent manufacturing processes and material properties, thus achieving both standardization benefits and adaptability
3Strength
If timber from old growth and slow growth replanted forests is used for pallet production, then structural integrity is improved, but environmental sustainability is worsened
Solution Approach 1:
The invention changes the material source parameter from natural timber (requiring old growth or slow growth forests) to a synthetic biodegradable polymer composite. This synthetic material can be engineered to achieve equivalent or superior structural integrity through molecular design and fiber reinforcement, while being produced from rapidly renewable plant resources, thus resolving the contradiction between strength and environmental sustainability
