Rotatable Handle Pole Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grippers with rotatable handle bars require cumbersome clamping nuts for operation, making it difficult to easily change the position of the implement relative to the handle, which hinders efficient use.
Innovation Solution
A tool with a rotatable coupling mechanism between the handle and pole, utilizing a first and second coupling element and an elastic member, where a movable button disengages the coupling to allow easy rotation of the pole relative to the handle without the need for clamping nuts, enabling the implement to be positioned according to user requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If clamping nuts are used to provide rotatable handle bars, then the handle and pole can be locked and unlocked for rotation, but the operation becomes cumbersome and inconvenient
Solution Approach 1:
The patent removes the clamping nut component from the system and replaces it with a button-actuated release mechanism. The button (122) directly actuates the first coupling element (116) to disengage from the second coupling element (118), eliminating the need for separate locking nuts and simplifying the operation to a single button press action.
Solution Approach 2:
The elastic member (120) provides automatic engagement of the coupling elements without requiring manual tightening operations. When the button is released, the elastic member automatically pushes the first coupling element to engage with the second coupling element, providing self-locking functionality that eliminates the need for threaded fasteners.
2Reliability
If conventional fixation mechanisms are used, then the handle and pole can be coupled, but the design becomes complex and difficult to use
Solution Approach 1:
The fixation mechanism is divided into distinct functional components: the first coupling element (116) attached to the handle, the second coupling element (118) attached to the pole, and the elastic member (120) providing the locking force. This segmentation allows each component to perform its specific function simply, avoiding the need for complex integrated fixation structures.
Solution Approach 2:
Instead of using a mechanism that requires active tightening and locking operations, the patent employs a spring-loaded automatic engagement system where the default state is locked and the button provides the active disengagement function. This inversion simplifies the mechanism by eliminating the need for threaded connections and multiple locking components.

Function Achieved in This Case
The solution allows for convenient and efficient operation by eliminating the need for clamping nuts, enabling the implement to be easily rotated and positioned, enhancing user comfort and operational efficiency.
Implementation Method 1
an elastic member (120) coupled with the pole such that the elastic member cooperates with the first coupling element (116) to force the first coupling element (116) to engage with the second coupling element (118)
Implementation Method 2
The handle (102) further includes a movable button (122) adapted to allow the first coupling element (116) to act against the elastic member (120) to disengage the rotatable coupling of the handle (102) and the pole (104)

AI summary
A tool (100) includes a handle (102) and a pole (104) extending from the handle (102) from a first end (106) towards a second end (108) along a central pole axis (PA). The tool (100) includes an implement (110). The tool (100) further includes a fixation mechanism (114) for coupling the handle (102) and the pole (104) together. The fixation mechanism (114) includes a first coupling element (116) associated with the handle (102), and a second coupling element (118) associated with an outer surface (105) of the pole. The first coupling element (116) and the second coupling element (118) are adapted to be selectively engaged together. An elastic member (120) coupled with the pole cooperates with the first coupling element (116) to force the first coupling element (116) to engage with the second coupling element (118) to rotatably couple the handle (102) and the pole (104) together. The handle (102) includes a movable button (122) to allow the first coupling element (116) to act against the elastic member (120) to disengage the rotatable coupling of the handle (102) and the pole (104).
