Flexible Utility Handle with Cable Tension Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility handles are limited by their inability to bend to accommodate user needs and return to a rigid configuration when more force is applied, requiring multiple handles for different tasks.
Innovation Solution
A flexible utility handle comprising an upper and lower tubular section connected by a coiled spring and tension cable, allowing the handle to bend at a 90-degree angle and adjust between flexible and rigid configurations through a cable tension bolt mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a utility handle is designed to be rigid for exerting force, then it can provide structural strength, but it cannot bend to accommodate user needs for angling the device
Solution Approach 1:
The handle incorporates a coiled spring mechanism that allows the handle to dynamically transition between rigid and flexible states. The spring enables bending motion when flexibility is needed, while maintaining structural integrity when force is applied, resolving the contradiction between adaptability and strength.
Solution Approach 2:
The handle's physical state is changed by adjusting cable tension through a cable tension bolt. By modifying the tension parameter of the cable, the handle can shift between flexible and rigid configurations, allowing the user to adapt the handle's mechanical properties to different task requirements.
2Adaptability or versatility
If a utility handle is designed as a single-purpose device, then it can be simple in structure, but the consumer needs numerous handles for different maintenance duties
Solution Approach 1:
The handle is designed with a universal attachment mechanism featuring a male threaded second end that can detachably attach various cleaning devices with female threaded attaching means. This allows a single handle to perform multiple functions by simply changing the attached device, eliminating the need for multiple single-purpose handles.
Solution Approach 2:
The handle is divided into modular sections (upper tubular section, lower tubular section) with standardized threading interfaces. This segmentation allows different cleaning devices to be attached and detached, creating a universal system where one handle can serve multiple purposes through component interchangeability.

AI summary
A flexible utility handle comprising a handle, an upper tubular section having a female threaded first end and a recessed second end, a lower tubular section having a recessed first end and a male threaded second end, a coiled spring flexibly connecting the upper tubular section and the lower tubular section, and a tension cable operationally connecting the handle and the lower tubular section. The handle includes a cable tension bolt which is operationally designed to engage the female threaded first end of the upper tubular section. Rotating the handle to increase the overall length of the invention decreases its flexibility at the coiled spring. Rotating the handle to decrease the overall length of the invention increases its flexibility at the coiled spring.
