Transportable Container Removable Handle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transportable containers with telescopic handles face structural complexity, reduced internal space, and accessibility issues, leading to increased costs and potential damage over time due to the need for internal bulkheads and inaccessible handle configurations.
Innovation Solution
A transportable container design featuring a removable handle interlocking mechanism with a U-shaped bracket and telescopic bars, allowing easy assembly, disassembly, and replacement without compromising internal space, using hooks and abutments integrated with the shell's existing components, such as the wheel shaft, and external grooves for reduced space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the handle is accommodated in an interspace inside the trolley case, then the handle can be protected when retracted, but the structural complexity increases due to the need for an inner bulkhead
Solution Approach 1:
The handle is extracted from the internal interspace configuration and positioned externally on the shell. The handle can be mounted on the external surface of the shell, eliminating the need for an inner bulkhead while still providing protection when retracted against the shell's outer surface.
2Reliability
If the handle is accommodated in an interspace inside the trolley case, then the handle can be protected when retracted, but the available internal space for storage is reduced
Solution Approach 1:
The handle accommodation is moved from the internal space to the external surface of the shell. When retracted, the handle rests against the outer surface of the shell, completely freeing up the internal storage volume while still providing protection for the handle mechanism.
3Reliability
If the handle is stably anchored to the trolley case, then the handle ensures stable operation, but the handle becomes inaccessible for repair or substitution
Solution Approach 1:
The handle assembly is divided into separable components that can be easily detached. The handle includes a mounting portion that can be removed from the shell through accessible fastening mechanisms located on the external surface, allowing for simple repair or substitution without compromising operational stability during use.
4Ease of operation
If the handle is repeatedly extracted from and reinserted into the interspace, then the handle can be adjusted, but the probability of damage increases over time
Solution Approach 1:
The handle incorporates a telescopic mechanism with smooth sliding surfaces and rolling elements that enable repeated extension and retraction movements. The external mounting on the shell provides stable guidance and support during these movements, reducing wear and damage compared to internal interspace accommodation.
