Pronged Band Connector for Elastic Exercise Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to securely and efficiently attach elastic exercise resistance bands to various structures, such as exercise stands or bars, due to lack of effective connectors that provide consistent resistance and easy adjustment.
Innovation Solution
A pronged band connector with a metal base and elongated rigid prongs, spaced to accommodate the band, allowing for secure attachment and adjustable tension through beveled tips and graduated markings, enabling secure fastening to various structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing connectors are used to attach elastic exercise bands, then attachment is possible, but the attachment is not secure and consistent resistance is not provided
Solution Approach 1:
The connector is divided into multiple functional elements: a base structure for stability, multiple prongs (typically three) for secure band engagement, and beveled tips for precise insertion. This segmentation allows each component to perform its specific function optimally, providing secure attachment while maintaining manufacturing simplicity.
Solution Approach 2:
The pronged connector acts as an intermediary element between the elastic exercise band and the anchor structure. It mediates the connection by providing a secure mechanical interface that ensures consistent resistance transmission while protecting both the band and the anchor structure from direct stress concentration.
2Ease of operation
If existing connectors are used, then attachment can be made, but adjustment and tension control are difficult
Solution Approach 1:
The beveled tips on the prongs provide localized functional quality that facilitates easy insertion and adjustment. The angled surfaces allow users to quickly adjust the band position and tension without requiring precise manufacturing of the entire connector, combining ease of operation with adequate manufacturing precision.
3Reliability
If a secure attachment mechanism is implemented, then resistance consistency improves, but the attachment process becomes less efficient
Solution Approach 1:
The prongs are pre-positioned and pre-oriented on the base structure, with beveled tips ready for insertion. This preliminary arrangement allows users to simply slide the band onto the prongs without requiring complex alignment or adjustment steps, achieving both secure attachment and high attachment efficiency.
Solution Approach 2:
The connector design allows the exercise band to secure itself to the prongs through simple insertion. The band's elasticity and theprongs' geometry work together to automatically create a secure connection without requiring additional fastening actions or complex user intervention, thereby maintaining high attachment efficiency while ensuring resistance consistency.

AI summary
A pronged band connector is adapted for securing a flat elastic exercise resistance band to an adjacent structure. The exercise band has a length, width, and thickness. The exemplary band connector comprises a base and a plurality of spaced-apart elongated rigid prongs. The prongs extend substantially perpendicular to the base, and are adapted for receiving a portion of the exercise band between adjacent prongs. A length of each prong may be greater than the width of the exercise band.
