Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical fastening mechanisms (buttons, hooks, loops) are used for strap closure, then the strap can be securely fastened, but the system becomes cumbersome, complex, and prone to stretching or tearing
Solution Approach 1:
The patent replaces traditional mechanical fastening mechanisms (buttons, hooks, loops) with a magnetic field-based clasp system. The magnetic clasping assembly generates magnetic attraction forces that secure the strap without requiring complex mechanical interlocking parts, thereby reducing device complexity while maintaining fastening security
Solution Approach 2:
The invention extracts and removes the complex mechanical fastening components from the strap closure system, retaining only the essential magnetic attraction function. This eliminates unnecessary mechanical parts that cause complexity and potential failure points
2Reliability
If traditional mechanical fastening mechanisms with holes are used, then the strap can be fastened at specific positions, but the system lacks adjustability and is prone to stretching or tearing at attachment points
Solution Approach 1:
The magnetic clasp system enables dynamic adjustment of strap length and positioning. The strap can be freely extended or retracted within the magnetic field's effective range, allowing continuous position adjustment rather than fixed holes. The magnetic force dynamically adapts to maintain secure fastening at any position within the operational range
Solution Approach 2:
The system allows continuous variation of the strap's effective length and positioning parameters within the magnetic field's range. This continuous parameter adjustment capability replaces discrete hole positions, providing infinite adjustability while maintaining secure fastening through magnetic attraction
3Reliability
If complex mechanical fastening systems are used, then secure attachment is achieved, but the operation becomes less user-friendly and less elegant
Solution Approach 1:
The magnetic clasp system replaces complex mechanical operations (buttoning, hooking, looping) with simple magnetic attraction. The user simply needs to bring the strap ends together within the magnetic field's range, and the magnetic force automatically secures them, making the operation intuitive and user-friendly while maintaining secure attachment
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 magnetic clasp system offers a reliable, user-friendly, and aesthetically desirable solution for strap closure, preventing slippage and allowing for easy length adjustment, while maintaining magnetic connection, thus overcoming the limitations of traditional fastening methods.
Implementation Method 1
The mounting assembly has a magnetically responsive material configured to draw the clasping assembly and the mounting assembly together when within a magnetic field thereof
Implementation Method 2
This forcing of the bent loop out of the second end causes a natural spring force to cause the loop to want to expand and thus pull more of the strap through the clasping assembly
