Telescopic Container Handle Assembly for Tip-Resistant Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheeled containers lack effective mechanisms to prevent tipping over and facilitate stable, versatile handling in both upright and mobile positions.
Innovation Solution
A handle assembly with a telescopic handle and tilt support that can be manipulated between retracted and extended positions, providing additional ground support when needed, and a locking mechanism to secure these positions, allowing the container to be stabilized in various configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wheeled container is designed to be mobile, then it can be easily moved and transported, but it becomes unstable and prone to tipping over
Solution Approach 1:
The patent implements a dynamic stability system where the tilt support member transitions between retracted and extended positions based on the container's operational state. During mobile operation, the support is retracted to allow movement, while during rest, it extends to provide stability. This dynamic adjustment resolves the contradiction between mobility and stability by adapting the support structure to the current operational requirement.
Solution Approach 2:
The tilt support member is positioned to extend behind the rear rolling wheel assembly axis, creating a preliminary counterbalancing force that prevents tipping before it occurs. This preliminary anti-action is achieved by strategically placing the ground support contact point to generate a stabilizing moment that counteracts the tipping force, thereby preventing instability rather than merely responding to it.
2Volume of moving object
If a handle assembly is made telescopic to save space, then storage efficiency improves, but the mechanism becomes more complex
Solution Approach 1:
The patent combines the telescopic handle mechanism with the tilt support member into a single integrated assembly. The handle and support share common structural elements and actuation mechanisms, reducing the overall complexity that would result from having separate systems. This merging allows the handle to telescope for compact storage while the integrated tilt support provides stabilization, achieving space efficiency without proportionally increasing complexity.
