Bite-Resistant Cable Cover Layer with Capsaicin and Menthol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power cables are vulnerable to biting by pests like termites and rodents, leading to potential short circuits and fire hazards, with existing solutions either causing environmental harm or increasing production complexity and cost.
Innovation Solution
A bite-resistant cable design featuring a cover layer with capsaicin as a peppery agent (2-5 wt%) and menthol as an algefacient (2-5 wt%), optionally including an anti-insect agent (0.5-5 wt%), potentially in micro-capsules, and a shielding layer of glass fibers, to deter pests without toxic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high hardness plastic (e.g., nylon) is used to form the cover layer, then bite-resistant effect is improved, but production complexity and cost increase
Solution Approach 1:
The patent combines conventional plastic material with natural repellent substances (capsaicin from chili pepper extract and menthol from mint extract) to form a composite cover layer. This composite structure maintains the protective function of the plastic while adding pest-deterrent properties, eliminating the need for separate nylon layers and simplifying the production process.
Solution Approach 2:
The patent modifies the chemical composition parameters of the cover layer by incorporating specific concentrations of capsaicin (0.1-5 wt%) and menthol (0.1-5 wt%). These parameter changes transform the cover layer from a passive protective barrier to an active pest-deterrent, achieving bite resistance through chemical repulsion rather than mechanical hardness.
2Strength
If repellent agent is added to the cover layer, then bite-resistant effect is improved, but environmental harm and toxicity increase
Solution Approach 1:
The patent converts potentially harmful synthetic chemicals into beneficial natural substances. By using capsaicin and menthol from natural plant extracts, the patent transforms the cover layer into an environmentally friendly pest deterrent that protects against biting while being non-toxic to humans and the environment. These natural substances decompose harmlessly unlike persistent synthetic repellents.
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 cable effectively prevents rodent and termite bites in a non-toxic manner, ensuring a stable power supply and extending the cable's service life by up to 15-25 years while being environmentally friendly.
Implementation Method 1
The peppery agent is capsaicin and the content thereof is between 2 wt % and 5 wt % of the total weight of the cover layer
Implementation Method 2
The algefacient is menthol and the content thereof is between 2 wt % and 5 wt % of the total weight of the cover layer
Data Source
AI summary
A bite-resistant cable includes at least one core cable and a cover layer surrounding the at least one core cable. The cover layer contains a peppery agent and an algefacient. The content of the peppery agent is between 0.5 wt % and 5 wt % of the total weight of the cover layer. The content of the algefacient is between 0.5 wt % and 5 wt % of the total weight of the cover layer. Therefore, the service life of the cable can be extended and a stable power supply can be provided.
