Lockable Zipper Container with Integrated Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many zipper containers are not securely closed, allowing unauthorized access to items, which can lead to injury, exposure of personal items, or damage to the contents.
Innovation Solution
A lockable zipper container with a locking arrangement featuring interdigitating rows of teeth and a slider with a Y-shaped channel, combined with a lock latch that engages with a combination lock or key lock mechanism, preventing access when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a zipper container is designed to be easily accessible, then ease of operation is improved, but security and prevention of unauthorized access deteriorates
Solution Approach 1:
The zipper slider incorporates a dynamic locking mechanism that transitions between locked and unlocked states. The lock latch pivots between engaged and disengaged positions, allowing the container to switch between secure locked state and accessible unlocked state based on user authorization through combination lock or key lock interaction.
Solution Approach 2:
The lock latch acts as an intermediary component between the zipper slider and the locking arrangement. It mediates the interaction by receiving input from the combination lock or key lock and translating it into the mechanical action of engaging or disengaging the lock, thereby controlling access to the container contents.
2Reliability
If a locking arrangement is added to the zipper, then security is improved, but device complexity increases
Solution Approach 1:
The locking arrangement is merged with the existing zipper slider assembly. The lock latch is integrated into the slider structure, and the combination lock or key lock is incorporated directly into the zipper mechanism, combining the sealing function of the zipper with the security function of the lock in a unified assembly rather than separate components.
Solution Approach 2:
The zipper slider serves multiple functions: it controls the opening and closing of the zipper teeth, operates the lock latch mechanism, and interfaces with the combination lock or key lock. This multi-functionality reduces the need for separate dedicated locking components, thereby limiting the increase in overall device complexity.
3Ease of operation
If the lock latch is made movable relative to the slider, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The lock latch is designed with controlled mobility relative to the slider, pivoting on a defined axis within the slider body. This dynamic design allows the latch to move between engaged and disengaged positions while the pivot mechanism and guide structures maintain precise alignment during movement, balancing operational ease with manufacturing precision requirements.

AI summary
A container that includes a lockable zipper. The container includes a cavity having an opening. A zipper is provided that includes first and second rows of teeth and a slider. The first row of teeth is connected on one side of the opening and the second row of teeth is connected on an opposite side of the opening. The slider is configured to cause the rows of teeth to mesh together when the slider is moved to the closed position and to cause the rows of teeth to separate when moved to the open position. A locking arrangement is provided that includes a lock mechanism and a locking latch opening. A locking latch is provided that is designed to be releasably connected to the locking latch opening. The locking latch is designed to prevent the slider from moving to a fully open position when the locking latch is locked in the locking latch opening. The locking latch is designed to allow the slider to move to a fully open position when the locking latch is released from the locking latch opening.
