Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional zipper is used for convenient operation, then ease of operation is improved, but the ability to detect closed state deteriorates
Solution Approach 1:
The patent implements a feedback mechanism by measuring the resistance value of the conductive loop formed by the slider, fastener stringer, and conductive coating. The resistance measuring chip continuously monitors the resistance change as the slider moves, providing real-time feedback about the zipper's closed state to the external control device, thus solving the information loss problem while maintaining operational convenience
Solution Approach 2:
The patent replaces the traditional mechanical closed-state detection method with an electrical measurement system. Instead of using mechanical sensors or switches, the invention uses a conductive coating on the fastener stringer and measures electrical resistance through the slider to determine the zipper's closed state, achieving more reliable detection without compromising ease of operation
2Measurement precision
If a smart detection system is added to the zipper, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent changes the physical parameter of the fastener stringer by adding a conductive coating to its outer surface. This simple parameter change enables the formation of a conductive loop that can be measured for resistance, providing accurate closed state detection without requiring complex mechanical or electronic structures within the zipper itself
Solution Approach 2:
The patent introduces a conductive coating as an intermediary element between the slider and the fastener stringer. This conductive layer acts as a mediator that enables electrical contact and resistance measurement, allowing the detection system to function with minimal modification to the traditional zipper structure

AI summary
A smart zipper includes: a fastener stringer including two rows of zipper teeth and a joint at one end of the two rows of zipper teeth for fixedly connecting the one end of the two rows of zipper teeth; a slider, including two lateral limiting portions, the two lateral limiting portions having conductive properties, and the two lateral limiting portions respectively electrically contacting outer edges of the two rows of zipper teeth; and a resistance measuring chip electrically connected to the two lateral limiting portions of the slider respectively, wherein the resistance measuring chip, the slider and the fastener stringer form a conductive loop. The resistance measuring chip is used for measuring the resistance value of the conductive loop, and outputting a measurement signal. The smart zipper provided by the present disclosure can detect its own closed state. Therefore, the user can know the closed state of the zipper in real time to avoid embarrassment or property loss due to unclosed zipper.
