Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable ties with antimicrobial additives face issues with the propagation of antimicrobial resistant pathogens, particularly silver-resistant bacteria, in food processing and clinical settings, necessitating improved antimicrobial properties and detectability.
Innovation Solution
Cable ties incorporating a composition of base plastics like polyamide, polypropylene, and antimicrobial additives comprising zinc, copper, and other metallic ions, combined with detectable metal and X-ray detectable additives, which are effective against silver ion resistant pathogens and provide metal and X-ray detectability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical antimicrobial additives are used in cable ties, then bacterial and fungal growth is resisted, but antimicrobial resistant pathogens are propagated
Solution Approach 1:
The patent changes the chemical parameters of the antimicrobial additive by using zinc oxide and copper complexes instead of traditional silver ion additives. This parameter change maintains antimicrobial effectiveness while avoiding the development of silver-resistant pathogens, as the metallic ion complexes work through different mechanisms that do not induce the same resistance patterns.
Solution Approach 2:
The patent employs a composite antimicrobial system combining zinc oxide particles with copper ion complexes. This composite approach creates a multi-component antimicrobial mechanism that is more difficult for pathogens to develop resistance against, as they would need to simultaneously resist multiple metallic ions with different modes of action rather than a single silver ion system.
2Ease of manufacture
If cable ties are made without detectable additives, then manufacturing is simpler, but detectability in food processing and clinical settings is reduced
Solution Approach 1:
The patent incorporates detectable additives that provide visual or instrumental detectability to the cable tie. These additives may include colorants or other detectable materials that allow the cable tie to be easily identified in food processing and clinical environments without complicating the basic molding and manufacturing processes.
3Strength
If metallic barb material is used in the head, then securing strength is improved, but metal detectability interference may occur
Solution Approach 1:
The patent applies metallic barb material locally only where mechanically needed for securing strength in the head portion, while the body of the cable tie contains the detectable additives. This localized application ensures that metal detection systems can still identify the cable tie through the detectable additives in the body, while the metallic barb provides necessary mechanical function without creating widespread metal detection interference.
