Triangular PVC Resistance-Band Frame for Seated Exercise Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices are either costly, complex to assemble, limited in functionality, or unsafe for seated exercises, particularly for individuals of varying statures and abilities, as they often require standing or use non-anchored elastic bands.
Innovation Solution
A lightweight, easy-to-assemble triangle-shaped apparatus made from one-inch PVC polyvinyl chloride with a unique 45-degree angled framework and four-inch wide elastic resistance bands, allowing for balanced seated exercises that target both upper and lower extremities and core muscles, with adjustable resistance levels and secure anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing exercise devices use non-anchored elastic bands, then the device is simpler and cheaper, but it becomes unsafe for seated exercises
Solution Approach 1:
The apparatus is divided into multiple sections (first section with first base, second section with second base) that can be assembled together. This segmentation allows the device to achieve stability and safety through proper structural configuration while maintaining ease of assembly and disassembly, resolving the contradiction between safety and complexity.
Solution Approach 2:
The apparatus includes pre-configured anchoring mechanisms and structural elements designed to securely hold elastic bands during seated exercises. By incorporating these safety features into the basic design rather than adding them later, the device achieves reliability without excessive complexity.
2Adaptability or versatility
If existing exercise devices require standing position, then the device structure can be simpler, but it limits usability for individuals who cannot stand
Solution Approach 1:
The apparatus is designed to accommodate multiple exercise positions and user abilities. The dual-base structure with configurable elastic band attachments enables both standing and seated exercises, making the device universally applicable to different user needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The apparatus allows dynamic adjustment of exercise configurations. Users can modify the setup for different exercise types (standing vs. seated) by repositioning elastic bands and adjusting components, enabling the simple structure to adapt to various usability requirements.
3Strength
If existing exercise devices use more PVC connectors and pipes, then the structural strength increases, but the assembly cost and labor increase
Solution Approach 1:
The apparatus is divided into sections that can be assembled from fewer individual components. By optimizing the connector and pipe arrangement in each section and designing efficient connection points, the device achieves necessary structural strength while minimizing the total number of parts, thereby reducing assembly cost and labor.
Solution Approach 2:
Multiple structural functions are combined into fewer components. The bases and connectors are designed to perform both structural support and exercise function simultaneously, reducing the need for separate components and lowering overall assembly complexity and cost while maintaining strength.
4Ease of operation
If the apparatus is made portable and disassemblable, then storage and transport become easier, but the structural stability during exercise may be compromised
Solution Approach 1:
The apparatus is segmented into modular sections that can be easily assembled and disassembled. Each section is designed with connection mechanisms that provide sufficient stability when assembled, while allowing straightforward separation for portability. The segmentation enables both ease of operation and structural stability to coexist.
Solution Approach 2:
The bases are designed with curved surfaces that provide stable contact with the ground during exercise. The curved geometry distributes weight and forces more effectively, enhancing structural stability during use while maintaining the ability to disassemble for portability when not in use.

AI summary
A functional triangular apparatus for multi-exercise of lower and upper extremities using resistance bands encircling designated parts. When exercising legs the triangular apparatus is stationary or tilted back at various angles to balance on two feet. Arms exercise with stretch bands under elevated larger base while feet hold it down.
