Biodegradable Adhesive Body Shield for Food Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable body shields in the food service industry are non-biodegradable, unsanitary, and do not effectively prevent the transmission of contaminants from clothing to food or provide antimicrobial protection, posing health risks and environmental hazards.
Innovation Solution
A disposable body shield made of biodegradable, impermeable synthetic or non-woven material with adhesive elements for secure attachment to the body, providing antimicrobial protection and preventing contamination by covering the torso and upper legs, with optional arm and leg coverings for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If disposable body shields are made of non-biodegradable plastic film, then they provide effective contamination protection, but they cause environmental hazards and toxins
Solution Approach 1:
The patent changes the material parameter from conventional non-biodegradable plastic to biodegradable materials such as polyhydroxyalkanoates (PHA), polylactic acid (PLA), or cellulose-based materials. This parameter change maintains the protective function while eliminating environmental toxicity, as the biodegradable materials break down into harmless substances after use.
Solution Approach 2:
The patent employs composite material structures combining biodegradable base materials with functional coatings. The composite includes a biodegradable substrate providing structural integrity and protection, combined with antimicrobial coatings or moisture-barrier layers that enhance contamination prevention while maintaining biodegradability.
2Ease of operation
If reusable cloth aprons are worn multiple times without cleaning, then they are convenient for workers, but they allow bacteria and virus particles to accumulate and cause cross contamination
Solution Approach 1:
The patent implements a disposable body shield that is used once and then discarded, eliminating the need for cleaning and reuse. Each shield provides fresh contamination protection, ensuring that bacteria and virus particles do not accumulate on the protective covering, while the low cost of the disposable unit makes it economically viable.
3Adaptability or versatility
If workers do not wear aprons during breaks, then they have freedom of movement, but they risk contaminating food with particles from unsanitary environments
Solution Approach 1:
The patent designs the body shield with dynamic attachment features including adhesive strips that can be applied to bare skin or garments, and adjustable fastening systems that allow the shield to be securely worn during work and easily removed during breaks. This dynamic design provides contamination protection when needed while allowing complete freedom of movement when the shield is removed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shield effectively prevents the transmission of germs and contaminants to clothing and food, is easy to use and dispose of, and reduces environmental impact, while offering antimicrobial protection and customizable branding options.
Implementation Method 1
the disposable body shield is provided with an adhesive element attaching directly to one's bare skin or garment
Implementation Method 2
The disposable body shield is made of a non-woven biodegradable material
