Variable Resistance Band Assembly for Adjustable Fitness Workouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment, particularly in gyms and outdoor settings, often requires users to switch between different resistance levels for various exercises, which is time-consuming and frustrating, and may lead to incomplete workouts due to long wait times for machines or lack of intensity variation.
Innovation Solution
A fitness station with a detachable and adjustable resistance band assembly that allows users to easily change resistance levels by engaging the band with multiple attachment points, including those above head level, using a tubular housing with resilient members that can be customized for different exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users switch between different resistance levels for various exercises, then workout intensity can be adjusted, but time is lost due to equipment changes
Solution Approach 1:
The resistance band assembly is designed to provide multiple resistance levels through a single device by incorporating multiple resilient members (bands) of different resistances within one assembly. The housing contains several bands that can be selectively engaged, allowing the same assembly to serve multiple resistance needs without requiring separate equipment for each level.
Solution Approach 2:
Multiple resilient members (inner band, middle band, outer band) are nested within each other inside the housing. Each band is positioned concentrically, with the innermost band providing highest resistance and outer bands providing progressively lower resistance. This nesting allows compact storage of multiple resistance levels within a single assembly.
2Adaptability or versatility
If multiple resistance bands are used, then resistance variety increases, but device complexity increases
Solution Approach 1:
A single housing structure performs multiple functions: it contains, protects, and manages multiple resilient members while providing a unified attachment interface. The housing acts as an integrated system that simplifies the user experience despite containing complex internal arrangements of multiple bands.
Solution Approach 2:
The nested arrangement of resilient members within the housing creates an organized, space-efficient structure. Each band is positioned within the housing in a specific radial position, with attachment mechanisms that allow selective engagement without requiring complex external assembly or disassembly procedures.
3Adaptability or versatility
If attachment points are located above head level, then exercise range increases, but ease of operation decreases
Solution Approach 1:
The attachment assembly extends outwardly from the housing in a direction perpendicular to the longitudinal axis of the housing. This lateral extension positions the attachment point at a height suitable for overhead exercises, allowing the housing to remain at a comfortable holding level while the attachment interface reaches the necessary vertical position.
Solution Approach 2:
The attachment assembly acts as an intermediary element between the housing and the exercise equipment attachment point. It provides a convenient interface that the user can easily grasp and manipulate, serving as a mediator that translates the user's hand movements into secure attachment or detachment of the resistance band assembly.

AI summary
A variable resistance band assembly may include a first end and a second end spaced apart from the first end. Additionally, a first disc is proximate the first end defining a plurality of holes arranged in a pattern extending through the first disc, and a second disc is stacked adjacent the first disc along an assembly axis, the second disc defining a plurality of holes arranged in a similar pattern to that of the first disc and axially aligned therewith. A connector is proximate the second end and a first resilient member is releasably attached to the connector and extending through one aligned hole in the first and second discs and releasably attached to the first disc.
