Foldable Handle Structure for Compact Mobile Apparatus Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile apparatuses face challenges in terms of portability and storability due to their size, making it difficult to fit them into small spaces or easily carry them when not in use.
Innovation Solution
A handle device with a foldable and adjustable structure, comprising a handle upper region and a handle lower region that can be coupled and decoupled via a shaft member with a screw thread region, and featuring concave-convex parts for secure coupling, allowing the mobile apparatus to be compactly stored and easily transported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile apparatus is designed with a fixed-size structure sufficient to accommodate the person and/or object to be transported, then the functionality and safety are ensured, but the portability and storability deteriorate as it becomes difficult to fit into small spaces or carry when not in use
Solution Approach 1:
The handle device is divided into multiple segments: a first body, a second body, and a shaft member that can penetrate through both bodies. This segmentation allows the handle device to be folded or reconfigured into a compact state when not in use, while maintaining its full functional size when needed for transporting persons or objects.
Solution Approach 2:
The handle device incorporates a dynamic structure with a shaft member that can penetrate and rotate within the first and second bodies, allowing the device to transition between extended and folded configurations. This dynamic capability enables the mobile apparatus to adapt its size based on usage requirements, improving portability without sacrificing functionality.
2Ease of operation
If the mobile apparatus is designed with a larger size to ensure stability and comfort during transport, then the usability is improved, but the ease of storage and transportation deteriorates as it requires more space
Solution Approach 1:
The second body is disposed towards an end of the first body with its second surface facing the first surface of the first body, creating a nested or overlapping configuration. The shaft member penetrates through both bodies, allowing them to be closely aligned and compacted together when folded, reducing the storage space required while maintaining usability when extended.
3Ease of manufacture
If the handle device uses a simple coupling structure between the first body and second body, then the manufacturing complexity is reduced, but the reliability of the coupling deteriorates
Solution Approach 1:
The shaft member features a screw thread region on its outer surface, providing a curved threaded structure that engages with corresponding threaded holes in the first and/or second bodies. This curved threaded coupling mechanism enhances the reliability of the connection between components while maintaining relatively simple manufacturing processes for the threaded features.

AI summary
A handle device may include a handle upper region, a handle lower region disposed below the handle upper region, and a shaft member configured to penetrate the handle upper region and the handle lower region in a region in which the handle upper region and the handle lower region face each other. A screw thread region provided on an outer surface of the shaft member may be configured to be screw-coupled to the handle upper region and/or the handle lower region at a portion where the shaft member penetrates the handle upper region and the handle lower region. The handle upper region may include an upper concave-convex part, and the handle lower region may include a lower concave-convex part. The lower concave-convex part may have a shape corresponding to the upper concave-convex part so that the handle lower region is able to contact the handle upper region.
