Luggage Lockset Top-Surface Inversion for Embedded Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locksets for luggage cases are prone to damage from impact, require inconvenient operation, and increase costs due to their design and the need for additional components, especially when used with large zippers, and complicate border inspections.
Innovation Solution
A lockset design featuring a housing with rotating clamping hooks and a lock body that can be opened by pressing the top surface, allowing for embedded design, reduced damage risk, and easier operation, with flexible design and compactness, and includes a second lock cylinder for independent unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the unlocking key is located on the side surface of the lockset, then the lockset can achieve locking function, but the embedded design cannot be adopted and the probability of damage due to impact on the box body cannot be reduced
Solution Approach 1:
The patent inverts the traditional side-mounted unlocking key design by placing the unlocking key on the top surface of the lockset. This inversion allows the lockset to采用 embedded design while maintaining accessibility for unlocking operations, thereby reducing damage probability from impact.
Solution Approach 2:
The patent transitions the unlocking key from a side-surface location to a top-surface location, utilizing a different spatial dimension. This dimensional change enables the lockset to be embedded flush with the box body surface while keeping the unlocking key accessible, thus reducing impact damage risk.
2Reliability
If the box body is relatively large and the zipper and the corresponding lock hole need to be additionally disposed, then the locking function can be achieved, but the cost is increased and the operation is not convenient
Solution Approach 1:
The lockset is designed with multiple insertion holes (first insertion hole, second insertion hole, third insertion hole) that can accommodate different zipper configurations. This multi-functionality allows the same lockset structure to serve various box body sizes and zipper arrangements without requiring additional components, thereby reducing complexity and cost.
Solution Approach 2:
The patent employs rotating clamping hooks that can dynamically adjust their positions to engage with zippers at different locations. This dynamic adaptability allows the lockset to maintain reliable locking function across different box body sizes and zipper configurations without increasing structural complexity.
3Reliability
If the first lock cylinder must be opened for border inspection, then the inspection can be conducted, but the time and labor costs are increased
Solution Approach 1:
The patent divides the locking system into two independent lock cylinders: a first lock cylinder for primary security and a second lock cylinder for inspection purposes. This segmentation allows border inspectors to open only the second lock cylinder for inspection without requiring the user to open the first lock cylinder, thereby reducing inspection time and effort while maintaining security.
Solution Approach 2:
The second lock cylinder acts as an intermediary mechanism that facilitates border inspections independently. It provides a dedicated interface for inspection operations, separating the inspection function from the primary security function, thus enabling faster and more efficient border control procedures.

AI summary
The lockset of the present disclosure includes a housing, a lock body, a first A clamping hook and a second A clamping hook. The housing includes a housing top surface, and the housing top surface includes a lock body embedding opening, and a first A insertion hole and a second A insertion hole which are located in two opposite sides of the lock body embedding opening. The lock body is disposed in the housing and includes a lock body top surface. The first A clamping hook corresponds to the first A insertion hole, and is capable of selectively rotating to open or close the first A insertion hole. The second A clamping hook corresponds to the second A insertion hole, and is capable of selectively rotating to open or close the second A insertion hole. When the lockset is in an unlocked state, the lock body top surface is capable of being pushed by an external force at a position adjacent to the first A insertion hole to generate a downward displacement, so that the first A clamping hook is rotated to enable the first A insertion hole to be open; and the lock body top surface is capable of being pushed by an external force at a position adjacent to the second A insertion hole to generate a downward displacement, so that the second A clamping hook is rotated to enable the second A insertion hole to be open.
