Dual Latch Assembly Synchronous Operation via Link Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch assemblies, including dual latch systems, face reliability issues over time due to fatigue, leading to degraded performance and frequent replacement needs, as they fail to consistently open or close openable structures.
Innovation Solution
The proposed latch system features a housing with a handle and a latching mechanism comprising guide pins, movable bodies with latching elements, and link assemblies that allow for synchronous operation of multiple latch assemblies, utilizing biasing members and assembly connectors to ensure proper latching and extended assembly life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional plunger assemblies are used in latch systems, then the latch can be operated with minimal effort, but the reliability degrades over time due to fatigue and the assembly fails to consistently open or close
Solution Approach 1:
The latch assembly is divided into multiple independent bodies (first body, second body, third body) that can move relative to each other along guide pins. This segmentation allows each body to be independently actuated while maintaining overall system reliability, as fatigue in one body does not necessarily compromise the others.
Solution Approach 2:
The latch system incorporates movable bodies that can dynamically transition between locked and unlocked positions along guide pins. The link connector and biasing members enable dynamic movement and automatic resetting, allowing the latch to adapt to wear and fatigue while maintaining reliable operation.
2Reliability
If multiple latches are employed to provide additional securing functionality, then the security is improved, but the system complexity increases and synchronous operation becomes difficult to maintain
Solution Approach 1:
Multiple latch assemblies are merged into a single integrated system through the link connector that couples the first and second bodies. This allows synchronous operation of multiple latches while maintaining a unified control mechanism, reducing overall system complexity compared to independent latch systems.
Solution Approach 2:
The link connector serves multiple functions: it connects multiple latch bodies, transmits actuation forces synchronously, and allows independent replacement of individual bodies. This multi-functionality reduces the need for separate mechanisms for each latch, simplifying the overall system.
3Productivity
If continuous use is made of the latch assembly, then the functionality is maintained, but fatigue occurs leading to degraded performance and frequent replacement requirements
Solution Approach 1:
The latch system allows individual bodies to be independently replaced while retaining the housing, guide pins, and link connector. This selective replacement capability enables recovery of the overall system without discarding functional components, extending the service life and maintaining productivity while addressing fatigue in specific worn bodies.

AI summary
Latch systems for opening and closing openable structures including a first latch assembly (500a), a second latch assembly (500b) separated from the first latch assembly (500a), and an assembly connector (560) operably connecting the first latch assembly (500a) to the second latch assembly (500b) such that operation of one of the first latch assembly (500a) and the second latch assembly (500b) causes operation of the other of the first latch assembly (500a) and the second latch assembly (500b) through the assembly connector (560). Lateral movement of a portion of the first latch assembly (500a) in operation causes lateral movement of the assembly connector (560) which causes lateral movement of a portion of the second latch assembly (500b) to thus operate the second latch assembly (500b).
