Elastic Core Tool Support Strap for Extended Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoulder strap systems for handheld power tools limit user flexibility and the ability to extend the tool away from the body, as they often feature non-elastic or fixed-length straps that encircle the neck and shoulder, restricting movement and access to remote areas.
Innovation Solution
A tool support strap with an elastic core throughout its central segment, surrounded by a self-centering shoulder pad and adjustable non-elastomeric webbing for user sizing, allowing for greater extension and flexibility, featuring a central elastic core and an expansible elastomeric outer sheath, with secure attachment via a cinch or spring clip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a non-elastic or fixed-length strap is used, then the strap provides structural stability and support, but the user flexibility and ability to extend the tool away from the body is limited
Solution Approach 1:
The strap transitions from a fixed-length non-elastic structure to a dynamic extensible structure with an elastic core that allows the strap to change length during use, enabling users to extend the tool away from their body while maintaining support functionality
Solution Approach 2:
The strap's length parameter is made variable through the incorporation of an elastic core material, allowing the strap to dynamically adjust its length between a retracted and extended state, thereby improving user flexibility without compromising structural integrity
2Ease of operation
If an elastic portion is added to the strap, then user flexibility is improved, but the strap complexity increases with dual component construction
Solution Approach 1:
The strap employs a composite construction combining an elastic core material with an elastomeric covering, creating a unified extensible strap structure that integrates multiple material properties (elasticity, protection, comfort) into a single cohesive component rather than separate assemblies
3Reliability
If the strap encircles the neck and shoulder, then the tool is supported on the user's body, but the ability to reach remote areas is restricted
Solution Approach 1:
The extensible nature of the strap allows users to dynamically adjust the tool's position by extending the strap to reach remote areas while the tool remains supported on the user's body through the encircling portion, combining stable support with extended reach capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to reach and maneuver tools over a greater distance without repositioning, providing enhanced control and access to areas previously inaccessible due to the strap's extended length and adjustable design.
Implementation Method 1
an inner, elastic core throughout the entire central segment of the strap
Implementation Method 2
a self-centering shoulder pad
Data Source
AI summary
A tool support strap is disclosed that has an inner, elastic core throughout the entire central segment of the strap with an elastomeric covering over the inner core. Encircling the elastic core is a self-centering shoulder pad. Adjustable straps are provided to adjust for the girth and the arm length of the user, which may be done through a central buckle, clip, or the like.
