Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing selfie sticks have a fixed connection between the handle and long rod, limiting the full use of the long rod's length while compromising portability, as the tail end of the rod must retract into the handle for compactness.

Innovation Solution

A handle sliding structure where the handle is a cavity structure slidably arranged on the long rod, allowing the long rod to extend fully when in use and retract partially into the handle for improved portability, featuring a sliding sleeve, holding part, and limiting parts for stable sliding and secure connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the handle and long rod are fixedly connected, then the structure is simple and stable, but the long rod cannot be fully extended and portability is compromised

Engineering Contradiction:

Improvelength of long rodVSAvoidconnection structure

Core Design Contradiction:

Length of moving objectVSDevice complexity

Solution Approach 1:

The connection between the handle and long rod is changed from fixed to dynamic/slidable. The handle can slide along the long rod's central cavity, allowing the long rod to extend fully when needed while still being connectable to the handle through the sliding mechanism, thus resolving the contradiction between full length utilization and structural simplicity.

Inventive Principle:

Principle #15Dynamics

2Volume of moving object

If the long rod retreats fully into the handle for portability, then the compactness is improved, but the length of the long rod cannot be fully used

Engineering Contradiction:

ImprovecompactnessVSAvoidlength of long rod

Core Design Contradiction:

Volume of moving objectVSLength of moving object

Solution Approach 1:

The slidable connection allows the long rod to dynamically adjust its position relative to the handle. When not in use, the long rod can partially retreat into the handle's central cavity for compact storage, but when needed, it can be fully extended outside the handle, thus resolving the contradiction between compactness and full length utilization.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the handle is made as a cavity structure for sliding, then the adaptability is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvesliding functionalityVSAvoidhandle structure

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The handle is segmented into an outer housing and an inner sliding component. The central cavity is created as a separate structural element within the handle, allowing the sliding mechanism to be manufactured as distinct parts that can be assembled together, thus reducing the overall manufacturing complexity while maintaining the sliding functionality.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention discloses a handle sliding structure and a selfie stick using the same, and belongs to the field of selfie sticks. The handle sliding structure comprises a long rod and a handle, wherein the handle is a cavity structure and is slidably arranged on the long rod, and the long rod can slide along the handle to retreat into or stretch out a cavity. When the selfie stick is used, the long rod can stretch out of the handle, and only the tail end of the long rod is connected to the handle, so that the length of the long rod is fully used; and when the selfie rod is not used, the long rod can partially retreat into the handle in the length direction, so that the portability is good.
