Integrated Elastic Latching Mechanism for Low-Profile Fliptop Lids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fliptop units lack an effective and compact positive lock mechanism that prevents accidental lid movement while allowing the lid to close with extended cables in use, and fail to maintain a low profile.
Innovation Solution
An integrated latching mechanism with a slider button, curved elastic arms, and a locking part that distorts upon external force removal, allowing the lid to be released and then automatically lock when closed, ensuring secure closure without obstructing cable extension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a positive lock mechanism is added to prevent accidental lid movement, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the locking mechanism, spring, and button into a single integrated assembly. The locking arms, spring, and button work together as one unified system rather than separate components, reducing overall device complexity while maintaining reliable locking functionality.
Solution Approach 2:
The spring-loaded locking mechanism automatically engages and disengages without requiring complex control systems. The spring provides automatic resetting action, and the button mechanism allows simple manual operation, making the system self-regulating and reducing operational complexity.
2Reliability
If a positive lock mechanism is added to prevent accidental lid movement, then reliability is improved, but the lid and bezel profile increases
Solution Approach 1:
The locking arms are positioned within the housing structure and engage with features on the lid. The mechanism is nested within the existing bezel and housing geometry, allowing the locking function to be achieved without significantly increasing the external profile of the lid and bezel assembly.
Solution Approach 2:
The locking mechanism operates in the vertical dimension through the spring-loaded arms that move up and down to engage and disengage locks. This vertical operation allows the locking function to be achieved without increasing the horizontal footprint or overall width of the lid and bezel.
3Ease of operation
If the lid is designed to close while cables are extended, then ease of operation is improved, but the risk of cable obstruction increases
Solution Approach 1:
The locking mechanism is designed to secure the lid in the closed position before cables need to be extended. The spring-loaded locks engage automatically when the lid is closed, establishing a secure state that prevents accidental opening during cable operations.
Solution Approach 2:
The button mechanism serves as an intermediary control that allows the user to intentionally release the locks when needed for cable extension. This deliberate action distinguishes between accidental opening (prevented by locks) and intentional opening (enabled by button), mediating between lid security and cable access needs.
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 mechanism effectively prevents accidental lid opening while allowing cables to be extended and retracted, maintaining a low profile and ensuring secure closure even when cables are in use.
Implementation Method 1
the urging of the slider button distorts the first and second curved elastic arms such that upon removal of the external force, the first and second curved elastic arms move the slider button and the locking part in the third direction

AI summary
An integrated latching mechanism includes a slider button. At least one curved elastic arm extends from the slider button and is configured such that in response to an external force urging the slider button in a first direction, the curved elastic arm is distorted such that upon removal of the external force, the curved elastic arm moves the slider button in a direction opposite to the first direction. A locking part is contiguous with the slider button and extends away from the slider button. In response to the external force urging the slider button in the first direction, the locking part moves in the first direction, and upon removal of the external force, the curved elastic arm moves the locking part in the direction opposite to the first direction. The at least one curved elastic arm, the slider button, and the locking part form a single piece of elastic material.
