Pull-out Carrying Handle with Sliding Slot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pull-out carrying handles for portable electronic devices require multiple components and complex assembly processes, increasing manufacturing costs and time, while also being prone to damage and difficulty in use due to excessive force distribution during handling.
Innovation Solution
A simplified design incorporating a single carrying handle with two links, each with protrusions and slots that allow for extensibility, clamping, and limiting mechanisms to enhance structural strength and ease of assembly, reducing the number of components and assembly complexity, and providing a comfortable grip with shock-absorbing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are used to achieve extensibility, then the carrying handle can be extended to accommodate different hand sizes, but the number of components and assembly complexity increases
Solution Approach 1:
The patent merges multiple components into a single integrated carrying handle structure that includes the handle body, extension mechanism, and connecting elements. This integration maintains the extensibility function while reducing the total number of separate components that need to be manufactured and assembled.
Solution Approach 2:
The carrying handle is designed as a multi-functional component that simultaneously provides holding capability, extension mechanism, and connection to the case. The single component structure performs multiple functions that would traditionally require separate parts, thereby reducing complexity while maintaining adaptability.
2Adaptability or versatility
If multiple components are assembled to achieve extensibility, then the carrying handle can be adjusted for different users, but the assembly time and manufacturing costs increase
Solution Approach 1:
By combining multiple functional elements into a single carrying handle component, the patent eliminates the need for complex multi-step assembly processes. The integrated design allows for quicker installation and adjustment, reducing the time loss associated with assembling multiple separate parts.
3Device complexity
If the carrying handle is fixed directly to the case, then the structure is simple, but it cannot be extended for different hand sizes
Solution Approach 1:
The carrying handle incorporates a dynamic extension mechanism that allows it to change length or configuration. This dynamic capability enables the handle to adapt to different hand sizes while maintaining a relatively simple overall structure when in its retracted or default state.

AI summary
A pull-out carrying handle is assembled to a case. The pull-out carrying handle includes a carrying handle and two links. Each of two ends of the carrying handle includes a first protrusion. Each of the links includes a first end and a second end, wherein the first end is assembled to the case, and the second end includes a sliding slot. The sliding slot of each link accommodates one first protrusion. With the single carrying handle, the first protrusions are respectively provided at two ends of the carrying handle, and the ends of the links having the sliding slots respectively accommodate the first protrusions. Thus, through the relative movements of the first protrusions and the sliding slots, the carrying handle can achieve an extensible effect.
