Luggage Zipper Lock with Integrated Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luggage locks on the market require complex operations and are prone to incorrect engagement due to the need to find lock holes, making them tedious and error-prone.
Innovation Solution
A luggage zipper lock with a combination lock mechanism that includes a slider, puller, lock hook pusher, and password disk system, allowing for simplified locking by sliding the locking portion into a lock hole without the need for precise alignment, using a digital password to unlock and lock the zipper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the puller is used to engage onto the luggage lock by inserting the holed part into the lock body, then the locking function is achieved, but the operation becomes tedious and error-prone due to the need to find lock holes and precise alignment
Solution Approach 1:
The patent introduces a lock guide structure as an intermediary component between the puller and the lock body. This guide structure includes a guide hole that aligns with the lock hole, automatically guiding the puller into the correct position during insertion. This mediator eliminates the need for users to manually find and align the lock hole, transforming a complex alignment task into a simple insertion motion.
Solution Approach 2:
The lock guide structure is pre-installed on the lock body in a fixed position, performing the alignment function in advance before the user attempts to lock the luggage. The guide hole is预先 positioned to match the lock hole, so when the user inserts the puller, the alignment is already prepared, eliminating the need for real-time adjustment or searching for the correct insertion point.
2Reliability
If the puller is used to engage onto the luggage lock, then the locking function is achieved, but the puller is prone to damage due to incorrect engagement
Solution Approach 1:
The lock guide structure serves as a protective intermediary that ensures the puller engages with the lock body in the correct position. The guide hole physically constrains the puller's insertion path, preventing misalignment that could cause damage to the puller or the lock mechanism. This intermediary structure acts as a safety guide, eliminating the risk of harmful incorrect engagement.
Solution Approach 2:
The lock guide structure provides a pre-prepared correct engagement path through the guide hole, cushioning against potential misalignment errors before they can cause damage. By having the correct alignment path ready in advance, the system prevents the puller from being forced into incorrect positions that could lead to mechanical damage.
3Reliability
If a combination lock mechanism is added to the zipper lock, then the security is improved, but the device complexity increases
Solution Approach 1:
The patent combines the combination lock mechanism with the existing zipper lock structure, merging two separate locking functions into a single integrated unit. The lock guide structure and combination lock are positioned and connected such that they work together as one system, eliminating the need for separate locking mechanisms and reducing overall structural complexity despite adding security functionality.
Solution Approach 2:
The lock body is designed to serve multiple functions: it provides the structural housing for the combination lock mechanism, contains the lock holes for zipper engagement, and incorporates the lock guide structure for alignment. This multi-functional design consolidates several components into one universal lock body, maintaining simplicity while adding security capabilities.

AI summary
A luggage zipper lock and a luggage, including a lock and a zipper, wherein the zipper includes a slider and a puller, the puller being provided on the slider, a first end of the slider is provided with a locking portion corresponding to the lock; when in a locked state, the locking portion on the slider is inserted into the lock and locked; when in an unlocked state, the lock is unlocked, and the locking portion on the slider can be pulled out from the lock. By moving the locked portion from the puller to the slider, the function of locking by pulling the slider is realized, which is simpler as compared to locking by buckling the puller into a lock hook, and the locking portion corresponds to the lock, so that only the zipper is pulled without making mistakes.
