Telescopic Luggage Handle Stabilizer for Wobble-Free Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telescopic handles in luggage are unstable due to clearances between inner and outer handle elements, leading to wobbling and undesired movement.
Innovation Solution
A stabilizing device is inserted between the inner and outer handle elements, comprising inner and outer stabilizing elements that create a frictional connection through pre-tensioned fits, preventing relative movement and stabilizing the handle elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clearances are provided between inner and outer handle elements for telescopic movement, then the handle can expand and retract, but the handle elements become unstable and wobble
Solution Approach 1:
A stabilizing device is introduced as an intermediary component between the inner and outer handle elements. This device includes a device body with an opening that receives the inner handle element, and stabilizing elements that contact both the inner and outer handle elements to prevent relative wobbling movement while allowing telescopic expansion and retraction
Solution Approach 2:
The stabilizing device is divided into distinct functional segments: a device body portion that provides structural support and an opening for inner handle element insertion, and separate stabilizing elements (inner and outer) that specifically address the wobbling issue. This segmentation allows each component to perform its specific function optimally
2Stability of the object's composition
If stabilizing elements are added to prevent wobbling, then handle stability improves, but device complexity increases
Solution Approach 1:
The stabilizing device merges multiple functions into a single integrated component: the device body provides structural support and guidance, while the inner and outer stabilizing elements work together to prevent wobbling. This consolidation reduces the need for multiple separate components and simplifies the overall assembly process
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 stabilizing device effectively reduces or prevents wobbling and tilting of the handle elements, ensuring stability while allowing for expansion and retraction of the telescopic handle.
Implementation Method 1
The inner stabilizing element and the outer stabilizing element are configured such that, in an installed position, the inner stabilizing element acts on the inner handle element and the outer stabilizing element acts on the outer handle element
