Telescopic Handle Rotating Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic handles in transportable containers, such as trolley cases, are prone to breakage due to protruding buttons that control the locking mechanism, leading to both functional and aesthetic issues.
Innovation Solution
A rotating handle part replaces the traditional button, converting rotational motion into translation motion to activate/deactivate the locking pins, enhancing solidity and efficiency while maintaining a flush aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protruding button is used to control the locking mechanism, then the button is easily accessible for operation, but the button is prone to breakage from impacts and has poor aesthetic appearance
Solution Approach 1:
The patent removes the protruding button from the exterior surface and integrates it into a recessed cavity in the handle. The button is extracted from its vulnerable protruding position and placed within the protected recess, eliminating exposure to impacts while maintaining operational accessibility through the cavity opening.
Solution Approach 2:
Instead of having the button protrude outward for easy access, the patent inverts the design by placing the button within a recessed cavity. The button remains accessible through the cavity opening but is protected from impacts by being surrounded by the handle structure, reversing the traditional protruding configuration.
2Ease of operation
If a protruding button is used to control the locking mechanism, then the button is easily accessible for operation, but the button disrupts the aesthetic continuity of the handle surface
Solution Approach 1:
The button is extracted from the exterior surface and placed within a recessed cavity, removing the visual disruption caused by protruding elements. The cavity is designed to be flush with or integrated into the handle surface, maintaining aesthetic continuity while providing access to the button through the recessed opening.
3Volume of moving object
If traditional telescopic rods with multiple tubular elements are used, then the handle size can be reduced when retracted, but the complexity of the locking mechanism increases
Solution Approach 1:
The patent combines multiple locking functions into a single integrated button mechanism. Instead of separate locking systems for each tubular element, the button simultaneously controls the locking and unlocking of all telescopic rods through a unified mechanism, reducing overall system complexity while maintaining the compact retracted form.
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 solution provides a robust, efficient, and aesthetically pleasing handle that reduces the risk of breakage and improves user experience by eliminating sticking parts and balancing forces during operation.
Implementation Method 1

AI summary
Telescopic handle for transportable containers, such as suitcases, trolley cases or the like, comprising an upper central elongated element (20) and two lateral elongate elements (30) connected to the central elongated element (20), the lateral elongated elements (30) moving from an extracted condition to a condition inserted in special seats provided inside said container. The central elongated element (20) moving from a maximum spaced apart condition, corresponding to the extracted condition, to a maximum approaching condition, corresponding to the inserted condition, with respect to said container, hooking means of at least one lateral elongated element (30) being present, configured to stably keep the extracted condition or the inserted condition. There are also means for activating/deactivating the said hooking means. The said activation/deactivation means consist of a handle part (21) belonging to the said central elongated element (20), the said handle part (21) being pivotally mounted with respect to the longitudinal axis of the central elongated element (20) and being configured so that the rotation of the said handle part (21) causes the said hooking means to be activated/deactivated.
