Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zippers with light-emitting devices suffer from erroneous electrical conduction due to external contacts, conduction failures from frictional wear and bending, and moisture exposure, leading to unreliable illumination in containers.
Innovation Solution
A zipper design with inner-facing conductive plates and a slider mechanism that ensures reliable electrical contact within a stop, preventing external interference and wear, while incorporating waterproof layers for moisture protection, ensuring stable illumination when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical contacts are disposed on zipper tapes and exposed on the outer face to enable lighting function, then the light-emitting unit can be activated, but the electrical contacts are apt to contact with conductive external objects causing erroneous electrical conduction
Solution Approach 1:
The patent extracts the electrical contacts from the outer face of the zipper tape and relocates them to the inner face, specifically positioning them within the stop structure. This extraction removes the harmful exposure to external conductive objects while preserving the essential lighting function through the slider contact mechanism.
Solution Approach 2:
The electrical contacts are nested within the stop structure on the inner face of the zipper tape. The stop acts as a containing structure that houses the electrical contacts, protecting them from external interference while allowing the slider to access and activate them through controlled contact.
2Adaptability or versatility
If electrical contacts are exposed on the outer face of the zipper to enable lighting, then the light-emitting unit can be activated, but frictional wear by the slider or bending of the zipper leads to poor contact and open circuit
Solution Approach 1:
The patent extracts the electrical contacts from the outer face where they were subjected to frictional wear and bending, and relocates them to the inner face within the stop structure. This extraction removes them from the wear-prone environment while maintaining their electrical function through the slider contact mechanism.
Solution Approach 2:
The stop structure serves as a protective cushioning element that houses the electrical contacts, shielding them from mechanical wear and bending forces before these harmful effects can occur. The stop structure provides a stable, protected environment for the electrical contacts.

AI summary
A zipper includes a tape body including two zipper tapes each having an inner edge with a row of teeth. A stop includes a first end connected to distal ends of the rows of teeth and receives two first conductive plates. An end of one of the two first conductive plates is electrically connected to an electrode of at least one light-emitting element. A power connecting portion is electrically connected to another of the two first conductive plates and another electrode of the at least one light-emitting element. A slider is slidably disposed on the rows of teeth for engaging or disengaging the rows of teeth. The slider includes a second conductive plate configured to simultaneously contact with the two first conductive plates, causing electrical conduction to activate the at least one light-emitting element to emit light. A container with the zipper is also provided.
