Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional attachment methods are used to secure protection devices to vehicles, then the protection device can be firmly attached, but the vehicle surface is damaged during attachment or removal
Solution Approach 1:
The patent replaces conventional mechanical attachment methods (screws, clips, adhesives) with a magnetic attachment system. The magnetic strip contains multiple magnets that provide strong holding force through magnetic attraction to the vehicle's metal surface, eliminating the need for mechanical fasteners that could damage the vehicle. The magnetic force can be easily overcome by pulling the device away, allowing damage-free removal.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical interlocking to magnetic field interaction. By utilizing magnetic field strength as the attachment parameter instead of mechanical force, the system achieves both strong attachment and easy, damage-free removal. The magnetic force can be precisely controlled through the selection and arrangement of magnets in the magnetic strip.
2Reliability
If the protection device is designed to provide comprehensive impact protection, then protection effectiveness is improved, but the device becomes harder to attach and remove without damage
Solution Approach 1:
The patent divides the protection device into distinct functional components: a magnetic strip for attachment, padding for protection, and a casing for structure. The magnetic strip is integrated into the casing, combining the attachment and protective functions in a unified device that is both effective and easy to operate.
3Reliability
If the padding is made highly protective against impacts, then protection performance is improved, but the padding becomes more susceptible to bacterial growth and requires complex maintenance
Solution Approach 1:
The patent uses composite materials for the padding, combining protective foam material with an antimicrobial coating or treatment. This creates a multi-functional material that provides both impact protection and bacterial resistance, eliminating the need for separate protective layers and simplifying maintenance.
