Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional securing devices (ropes, cables, chains) are used, then securing strength is achieved, but difficulty in finding proper size and length, and difficulty in removal occur
Solution Approach 1:
The patent applies parameter changes by specifying precise material properties including elongation greater than 400%, tensile strength between 4,500-9,300 kPa, dielectric strength between 200-700 volts per mil, and breakdown voltage between 30,000-60,000 volts. These parameter specifications enable the securing device to achieve both high securing strength and ease of operation through controlled material behavior
Solution Approach 2:
The patent employs composite materials by combining thermoplastic elastomers with styrene to create a device body that exhibits multiple desirable properties simultaneously: high elongation for flexibility, appropriate tensile strength for securing, and dielectric properties for safety. This composite approach resolves the contradiction by integrating multiple functions into a single material system
2Strength
If securing devices are made with high strength materials, then securing capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses composite materials consisting of thermoplastic elastomers and styrene to achieve the desired tensile strength range of 4,500-9,300 kPa. This composite material provides both the required strength and flexibility without requiring complex multi-component construction, thereby reducing device complexity while maintaining high securing capability
Solution Approach 2:
The patent optimizes the tensile strength parameter to fall within a specific range (4,500-9,300 kPa) rather than maximizing it indefinitely. This parameter optimization ensures sufficient securing strength while avoiding the need for overly complex or expensive high-strength materials, thus resolving the contradiction between strength and complexity
3Reliability
If securing devices are designed for specific applications, then securing effectiveness is improved, but adaptability to various objects decreases
Solution Approach 1:
The patent achieves universality by designing a securing device with a device body that exhibits elongation greater than 400%, enabling it to adapt to objects of various shapes and sizes. The standardized material properties and dimensions allow the same device design to be used across multiple applications, maintaining securing effectiveness while providing broad adaptability
Solution Approach 2:
The patent specifies key parameters including elongation >400%, body thickness between 70-140 mils, and specific tensile strength ranges. These parameter specifications create a versatile device that can effectively secure various objects while maintaining consistent performance characteristics across different applications
