Cooling Box Latch Handle Module for Secure One-Handed Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile cooling boxes are cumbersome to open, especially when using only one hand, as the lid must be lifted and held separately, which complicates access to the contents.
Innovation Solution
A mobile cooling box with a latch handle module that integrates an actuating element and locking element, allowing the lid to be pivoted open with one hand, featuring a snap-in latch mechanism and a spring-loaded design for easy operation and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is used to lock the lid from being lifted, then the lid can be securely locked, but the operation of opening the lid becomes cumbersome and requires two hands
Solution Approach 1:
The latch handle module combines the actuating element and locking element into a single integrated unit that performs both locking and opening functions. The locking element engages with the bracket to secure the lid, while the actuating element provides a convenient grip for one-handed operation to release the lock and open the lid.
2Device complexity
If the lid merely lies on the top rim of the box main body, then the structure is simple, but the user must hold the lid with one hand during loading and unloading
Solution Approach 1:
The latch handle module integrates the locking and actuating functions into a unified structure that is built into the lid. This allows the lid to remain structurally simple while providing a built-in handle that enables one-handed operation during goods loading and unloading, eliminating the need to separately hold the lid with the other hand.
3Ease of operation
If the lid is hinged to the box main body, then the lid can be pivoted open, but an additional latch mechanism is needed to keep it securely closed
Solution Approach 1:
The latch handle module merges the latch mechanism with the hinged lid structure. The locking element is integrated into the hinged lid assembly, allowing the lid to pivot open while the latch mechanism provides secure closure. The actuating element is built into the lid structure, creating a unified system that maintains security without adding separate complex latch components.
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
Enables comfortable and reliable one-handed opening and closing of the mobile cooling box, improving user convenience while maintaining secure storage conditions.
Implementation Method 1
The locking element is engageable with a corresponding counterpart at the box main body in order to lock the lid from being opened. The latch handle module provides a mechanism for locking and unlocking the lid. By operating the actuating element, the locking element disengages with the corresponding counterpart at the box main body and allows up-folding or lifting the lid.

AI summary
The present embodiments relate to an improved mobile cooling box with a latch handle module for opening the mobile cooling box, wherein the latch handle module is disposed in a lid for manually locking and unlocking the lid. At one edge the lid is hinged to the box main body so that the lid is pivotable from a closed position to an open position. The latch handle module is integrated in the lid and located at another side edge of the lid, opposite the hinge.
