Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pest repellents, including chemical and physical barriers, are ineffective against various pests, costly, and pose health risks or mobility issues, failing to provide comprehensive protection against diseases transmitted by small animals and invertebrates, especially in outdoor settings.
Innovation Solution
A full-body suit constructed from a protective material with a layered design, comprising a net layer, a three-dimensional mesh layer, and a comfort fabric layer, providing a physical barrier while maintaining breathability and flexibility, thus preventing pest contact and reducing disease transmission risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical repellents are used to repel pests, then pest repellency is improved, but health safety and reliability deteriorate due to irritants, allergens, and adverse side effects
Solution Approach 1:
The patent replaces chemical repellent systems with a physical barrier system consisting of layered fabric construction. The mechanical structure of multiple fabric layers with specific pore sizes physically blocks pests from contacting the skin, eliminating the need for chemical substances and their associated health risks while maintaining reliable pest protection.
Solution Approach 2:
The patent employs a composite fabric structure with multiple layers including outer fabric, mesh fabric, and inner fabric. Each layer serves specific functions: the outer fabric provides durability and pest blocking, the mesh fabric allows breathability while maintaining barrier function, and the inner fabric ensures comfort against skin. This composite approach achieves reliable pest protection without chemical harm.
2Reliability
If heavy clothing is used to provide physical barrier against pests, then protection reliability is improved, but temperature control and ease of operation deteriorate due to overheating and discomfort in hot weather
Solution Approach 1:
The patent uses thin, flexible fabric layers instead of heavy clothing. The fabric layers are constructed with controlled pore sizes that are small enough to block pests but large enough to allow air circulation and heat dissipation. This enables the garment to provide reliable physical barrier protection while maintaining thermal comfort through breathability.
Solution Approach 2:
The patent applies different fabric properties to different layers: the outer fabric has tight weave for pest blocking, the mesh fabric has open structure for breathability, and the inner fabric has soft texture for skin comfort. This local differentiation of material properties allows the overall system to provide both protection and temperature regulation.
3Reliability
If netting or mesh is used as physical barrier, then pest protection is improved, but ease of operation and adaptability deteriorate due to mobility restrictions and difficulty in active use
Solution Approach 1:
The patent constructs the protective garment from flexible fabric layers that can stretch and move with the body. The mesh and netting are integrated into flexible fabric structures rather than rigid frameworks, allowing the garment to maintain pest protection while adapting to various body movements and activities, thereby improving ease of operation during outdoor activities.
Solution Approach 2:
The patent creates a dynamic garment system where the fabric layers can dynamically adjust to body movements. The elastic and flexible nature of the fabric allows the protective barrier to expand and contract with muscle movement, maintain coverage during activity, and prevent pests from exploiting gaps, thus maintaining both protection reliability and operational ease.
4Reliability
If chemical repellents are reapplied frequently to maintain efficacy, then pest repellency reliability is improved, but loss of time and productivity deteriorate due to frequent reapplication requirements
Solution Approach 1:
The patent provides continuous pest protection through the physical barrier structure that remains effective throughout wear without requiring periodic reapplication. The layered fabric construction maintains its pest-blocking properties continuously from first wear, eliminating the time loss associated with frequent chemical reapplication while sustaining reliable protection.
Solution Approach 2:
The protective garment is self-maintaining in its protective function. The physical barrier structure does not degrade in effectiveness over time like chemical repellents, and requires no user intervention to maintain its protective properties. The garment serves itself by maintaining continuous protection through its inherent structural design, freeing the user from reapplication tasks.
