Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the attachment strap body is made as separate components (fabric strap body with separate fixing members and cooperating members), then the production process becomes complex and assembly is time-consuming, but the connection strength between members cannot be guaranteed and components may separate under external force
Solution Approach 1:
The patent merges the fabric strap body, fixing members, and cooperating members into a single integrally molded attachment strap body. This eliminates separate components and assembly steps, while ensuring unified structural strength throughout the entire attachment strap body, preventing component separation under external force.
Solution Approach 2:
The integrally molded attachment strap body performs multiple functions simultaneously: it provides the strap structure, incorporates fixing members for securing, includes cooperating members for cord connection, and ensures uniform strength distribution. This multi-functionality in a single component simplifies production while maintaining or improving connection strength.
2Reliability
If the cooperating member is designed to bear large forces, then it may accidentally separate from the attachment strap body due to excessive external force, but making it more robust increases device complexity
Solution Approach 1:
The cooperating member is merged into the attachment strap body as an integral component rather than a separate part. This ensures that the cooperating member and strap body move as a unified structure, eliminating the risk of accidental separation while maintaining the ability to bear large forces during surfing activities.
Solution Approach 2:
The attachment strap body is made from high-strength, flexible materials that can withstand large external forces while maintaining structural integrity. The material properties enable the integrated structure to bear surfing loads without requiring additional complex reinforcement structures.
3Strength
If the pull handle member is firmly connected to the attachment strap body, then it provides strength, but in emergency situations the user cannot quickly detach it, creating a safety risk
Solution Approach 1:
The patent incorporates a pull handle member that can be quickly pulled to detach the attachment strap from the user's body. The dynamic design allows the strap to remain firmly attached during normal use while enabling rapid release when the pull handle is pulled, providing both strength and emergency detachment capability.
Solution Approach 2:
The attachment strap body is designed with a separable mechanism where the pull handle member can be quickly detached from the main strap body in emergency situations. This segmentation allows the strap to function as a unified strong structure during use, yet can be divided for rapid release when needed.
4Productivity
If multiple separate components are used in the attachment strap, then assembly is complex and time-consuming, but using an integral structure may reduce manufacturing flexibility
Solution Approach 1:
The patent combines multiple components (strap body, fixing members, cooperating members) into a single integrally molded attachment strap body. This eliminates the need for separate assembly steps, significantly improving production efficiency and assembly speed while the molding process maintains manufacturing flexibility through adjustable mold designs.
Solution Approach 2:
The integral attachment strap body structure serves multiple functions simultaneously, reducing the number of parts that need to be manufactured and assembled. The universal design maintains manufacturing flexibility as the integral structure can be produced in various configurations through mold adjustments without requiring complex assembly processes.
