Automatic Telescopic Pole Lock Catch Against Accidental Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic telescopic poles are complex, risky due to unexpected extension/retraction, and lack shock absorption, compromising safety and user experience.
Innovation Solution
A simple and rational telescopic locking mechanism with a shift lock, oscillating ring, and shock absorbing spring, featuring a clasp-type telescopic locking device with a divided connecting sleeve and dual clasps for stable locking, and a lock catch to prevent accidental operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a clasp-type telescopic locking device with a driving rod is used, then automatic extension/retraction of the pole is realized, but the structure becomes complex and there is a risk of unexpected automatic extension/retraction due to accident operation
Solution Approach 1:
The patent removes the driving rod from the system entirely. Instead of using a driving rod to control the oscillating ring, the invention uses a direct button-press mechanism that actuates the locking clasp through a simplified lever arm, eliminating the complex driving rod mechanism while maintaining automatic extension functionality.
Solution Approach 2:
The locking mechanism is divided into separate functional components: a button for user input, a lever arm for motion transmission, and a locking clasp for securing. This segmentation allows each component to be simpler and more reliable, reducing overall system complexity while maintaining automation.
2Extent of automation
If a clasp-type telescopic locking device with a driving rod is used, then automatic extension/retraction of the pole is realized, but unexpected automatic extension/retraction may occur due to accident operation, endangering user safety
Solution Approach 1:
The patent incorporates a lock catch mechanism that preliminarily prevents accidental activation. The lock catch engages with the button to prevent unintended pressing, thereby preventing accidental extension/retraction before it can occur. This preliminary protective action eliminates the safety risk associated with accident operation.
3Extent of automation
If existing telescopic locking structures are used, then automatic extension/retraction is achieved, but there is no shock absorbing structure, resulting in poor user experience
Solution Approach 1:
The patent introduces a shock absorbing spring that is pre-installed in the telescopic mechanism. This spring provides cushioning before impact occurs, absorbing shock during the extension and retraction processes. The beforehand cushioning eliminates the poor user experience associated with harsh impacts, while maintaining the automatic operation functionality.
