Over-Center Latch Mechanism for Toolless Vibration-Resistant Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing securing mechanisms for components on vehicles and containers are inefficient, requiring tools and failing to securely hold objects under external forces like vibrations, and lack versatility in opening methods.
Innovation Solution
A latch mechanism using an over-centering orientation with a hook, lever, and link that secures components with minimal tool use, and a clamp mechanism that extends to secure objects under truck beds, along with a dual-access container opening system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing securing mechanisms are used, then components can be held in place, but they require tools and fail to securely hold objects under external forces like vibrations
Solution Approach 1:
The latch mechanism is designed to be toolless, allowing users to operate it with simple manual manipulation. The lever can be easily moved between locked and unlocked positions by hand, eliminating the need for specialized tools while maintaining secure holding capability under vibrations and external forces.
Solution Approach 2:
The patent removes the dependency on external tools by integrating all necessary latching and unlatching functions into the mechanism itself. The lever and latch body contain all required components, allowing the system to function independently without requiring separate tooling.
2Adaptability or versatility
If existing securing mechanisms are used, then components can be secured, but they lack versatility in opening methods
Solution Approach 1:
The latch mechanism incorporates multiple opening methods including manual lever manipulation and toolless release. The single latch body design can accommodate different operating modes, providing versatility in how the mechanism can be opened or closed without requiring multiple separate mechanisms.
3Reliability
If a latch mechanism with hook, lever, and link is used, then enhanced security against external forces is provided, but the device complexity increases
Solution Approach 1:
The latch body integrates multiple functions into a single component structure. The hook, lever pivot point, and link attachment are all incorporated into one unified latch body design, reducing the number of separate parts while maintaining the mechanical advantage and security against vibrations and external forces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The latch mechanism provides enhanced security against external forces without tools, while the clamp mechanism ensures objects remain secured, and the dual-access container opening facilitates easier access.
Implementation Method 1
A latch mechanism is disclosed that includes a hook, a lever, and a link that couples the lever with the hook such that movement of the lever causes movement of the hook.
Implementation Method 2
The latch mechanism can include a handle disposed at a first end of the lever. A force can be applied to the handle to cause the lever to move from the first lever position to the second lever position.
