Storage Case Locking Mechanism for Simultaneous Handle and Latch Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage cases with draw latch mechanisms face complexity in locking the handle and latch mechanism simultaneously due to their layout, requiring complicated structures and components.
Innovation Solution
A storage case design where the latch mechanism and handle are connected to a shared plane, with a locking mechanism that includes a linear lock plate to hook both latch and handle receiving portions in a single direction, simplifying the locking structure and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is designed to lock both the handle and latch mechanism simultaneously, then security is improved, but the structure becomes complicated depending on the layout of the handle and latch mechanism
Solution Approach 1:
The patent combines the handle and latch mechanism into a integrated unit where the handle serves dual functions: operating the latch mechanism and being locked simultaneously with it. The locking member engages both the latch and handle in a single locking action, merging two separate locking functions into one unified mechanism, thereby improving security without proportionally increasing structural complexity
Solution Approach 2:
The handle is designed with multi-functionality: it operates the latch mechanism, serves as a manual release, and is itself locked by the locking member. This universal design allows a single component to perform multiple security-related functions, reducing the need for separate mechanisms and simplifying the overall structure while maintaining reliable simultaneous locking
2Reliability
If the latch mechanism and handle are locked simultaneously, then durability is improved, but the number of components increases
Solution Approach 1:
The locking member is designed as a single integrated component that simultaneously engages both the latch mechanism and the handle. Instead of using separate locking components for each, this merged approach achieves durable simultaneous locking with fewer parts, directly addressing the contradiction between durability and component quantity
Solution Approach 2:
The locking member performs multiple functions: it locks the latch mechanism, locks the handle, and can be operated by a key or other actuating mechanism. This multi-functional design ensures durable locking of both components while minimizing the total number of parts required in the system

AI summary
A storage case where a case cover is openably and closably connected to a case body, the storage case included a latch mechanism fixing the case cover to the case body, a handle swingably connected to a plane to which the latch mechanism is connected, and a locking mechanism configured to lock the latch mechanism and the handle simultaneously. The latch mechanism includes a latch receiving portion configured to be hooked. The handle includes a handle receiving portion configured to be hooked. The locking mechanism includes a locking member hooking the latch receiving portion and the handle receiving portion. In a locked state, the latch receiving portion and the handle receiving portion are arranged in one direction.
