Telescopic Reel Handle Locking With a Wedged Clasp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional reeling apparatuses with fixed handles are inconvenient for users as they cannot be easily adjusted to a comfortable height, and conventional adjustable mechanisms lack sufficient locking force to secure the handle, leading to movement issues during use and transportation.
Innovation Solution
A reeling apparatus with a telescopic handle and a rotatable clasping element that locks into place using a bulged portion wedged between the handle and body walls, providing adjustable height and secure positioning through elastic deformation, allowing for easy handling and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed position handle is used in traditional spooling arrangements, then the structure is simple and stable, but the handle cannot be adjusted to a comfortable height for users
Solution Approach 1:
The handle is designed as a telescopic structure with multiple extendable sections that can be adjusted to different heights. The clasping element enables dynamic positioning by locking the handle at various heights, transforming the static fixed handle into a dynamic adjustable one, thus improving ease of operation while maintaining structural simplicity
Solution Approach 2:
The telescopic handle employs a nested structure where multiple cylindrical sections are inserted into each other. The clasping element with its bulged portion engages with grooves in the nested sections to lock the handle at desired heights, achieving height adjustment without significant increase in overall structural complexity
2Ease of operation
If conventional adjustment mechanisms are used to make the handle adjustable, then the handle height can be modified, but the locking force is insufficient to prevent movement during use and transportation
Solution Approach 1:
The clasping element is designed with a bulged portion that proactively engages with the grooves in the telescopic handle sections before movement occurs. This preliminary engagement creates sufficient locking force to prevent handle movement during use and transportation, ensuring reliable positioning at the selected height
Solution Approach 2:
The friction and resistance that typically oppose telescopic handle extension are converted into beneficial locking forces. The clasping element utilizes the interference fit and friction between the bulged portion and groove walls to maintain secure locking, transforming potential harmful forces into stabilizing mechanisms
3Adaptability or versatility
If the handle is made telescopic with adjustment features, then the handle can be customized to user reach, but the mechanism increases device complexity
Solution Approach 1:
The telescopic handle is designed with localized adjustment features rather than a completely complex mechanism. The clasping element with its simple rotatable design and bulged portion engages with grooves at specific locations on the telescopic sections, providing height customization through localized structural modifications rather than system-wide complexity
Solution Approach 2:
The clasping element is designed to be manually operated by the user without requiring additional tools or complex mechanisms. The user can easily rotate the clasping element to engage or disengage the bulged portion with the grooves, enabling self-service height adjustment and reducing the need for complex automated or tool-based adjustment systems

AI summary
A reeling apparatus (100) for spooling a flexible member therefrom includes a body (102) defining a first cylindrical passageway (104) extending axially therethrough, and a first recess (106) located partway along a length of the first cylindrical passageway (104). The first recess (106) extends radially away from an axis (XX') of the first cylindrical passageway (104) to be bound by a plurality of walls (108) from the body (102) that are arranged in a polygonal configuration about the axis (XX'). The reeling apparatus (100) also includes a telescopic handle (110) slidably disposed in the first cylindrical passageway (104) and extending through the first recess (106). Further, the reeling apparatus (100) includes a clasping element (112) located in the first recess (106) and disposed about the telescopic handle (110). The clasping element (112) has an outer circumference (C1) defining at least one bulged portion (114) thereon. The clasping element (112) is rotatable about the axis (XX') between an unlocked position (P1) in which the bulged portion (114) is disposed exterior to the first recess (106) so as to be located outwards of the body (102), and a locked position (P2) in which the bulged portion (114) is located within the first recess (106) and wedged between an outer circumference (C2) of the telescopic handle (110) and at least one proximate wall (108b) from the plurality of walls (108) so as to lock a position of the telescopic handle (110) in relation to the body (102).
