Telescopic Picker With Reel Lock for Easy Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telescopic pickers are complex to operate and inconvenient for length adjustment, often failing to ensure a normal clamping action and length extension control simultaneously.
Innovation Solution
A telescopic picker design featuring a handle body with a winding reel, a pipe fitting, and a clamping device, where a wire connected to the winding reel drives the clamping device, and a movable switch component controls the stopper to engage or disengage with a gear plate, allowing for adjustable length and reliable clamping actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the picker structure includes telescopic function with multiple components, then the length is adjustable, but the operation becomes complex and difficult to control
Solution Approach 1:
The patent combines the telescopic length adjustment function and the clamping action control into a single integrated handle body structure. The winding reel, wire, gear plate, and stopper mechanism are merged into one unified system, allowing both length adjustment and clamping operation to be controlled through a single handle assembly, thereby reducing operational complexity while maintaining adjustability.
2Adaptability or versatility
If the picker structure includes telescopic function with multiple components, then the length is adjustable, but the device complexity increases
Solution Approach 1:
The handle body is designed as a multi-functional component that simultaneously provides telescopic length adjustment, clamping action control, and structural support. The winding reel serves both to pay out and rewind the wire for length adjustment and to drive the clamping mechanism through the gear plate, reducing the need for separate dedicated components for each function.
Solution Approach 2:
The patent employs a nested structure where the wire is wound around the winding reel, which is nested within the handle body. The gear plate is nested within the handle body and interconnected with the winding reel, creating a compact hierarchical arrangement that reduces overall device complexity while maintaining telescopic functionality.
3Reliability
If the stopper is engaged with the gear plate to lock the winding reel, then the clamping action is stable, but the length adjustment becomes difficult
Solution Approach 1:
The stopper is designed as a movable component that can dynamically transition between engaged and disengaged states with the gear plate. When length adjustment is needed, the stopper disengages to allow the winding reel to rotate freely; when clamping stability is needed, the stopper engages to lock the winding reel. This dynamic state change allows the system to switch between adjustment and stabilization modes as required.
Solution Approach 2:
The stopper acts as an intermediary mechanism between the user's manual operation and the winding reel's rotation. By controlling whether the stopper engages with the gear plate teeth, it mediates between the desire for free rotation (length adjustment) and locked rotation (clamping stability), allowing smooth transition between these two operational states without mechanical conflict.

AI summary
A telescopic picker is provided, which includes a handle body, a pipe fitting, and a clamping device that are connected in sequence. The handle body is provided with a winding reel, and the winding reel is connected and wrapped with a wire; the wire passes through the pipe fitting and connects to the clamping device. A driving of the wire can drive the clamping device to perform a clamping action, and a length of the pipe fitting can be extended and retracted; a gear plate is connected to the winding reel, and a movable stopper is connected to the handle body through a reset member; the stopper is inserted between teeth of the gear plate to lock the gear plate. The stopper is disengaged from the teeth of the gear plate to unlock the gear plate. There is a movable switch component on the handle body.
