Solution Overview
Problem
Existing exercise roller devices lack a combination of rigidity and resilience, which limits their effectiveness in providing comprehensive spinal joint mobilization and tissue manipulation, particularly for self-massaging and stretching applications.
Innovation Solution
A composite exercise roller device comprising a substantially rigid inner roller connected to one or more soft or resiliently deformable outer roller panels, where the inner roller can be made of solid or hollow construction with reinforcing elements, and the outer roller panels are made of thermoplastic elastomer material, allowing for a combination of stiffness and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a solid rigid roller is used, then durability and structural stability are improved, but flexibility and tissue manipulation capability deteriorate
Solution Approach 1:
The roller combines a rigid inner shell made of durable material with an outer layer made of resiliently deformable material such as thermoplastic elastomer. This composite structure allows the device to maintain structural integrity while providing the flexibility needed for effective tissue manipulation and spinal joint mobilization.
Solution Approach 2:
Different regions of the roller have different material properties - the inner shell provides rigid structural support while the outer deformable layer provides localized flexibility and cushioning. This spatial differentiation of material qualities allows the single device to satisfy both rigidity and flexibility requirements.
2Adaptability or versatility
If a soft resilient roller is used, then flexibility and comfort are improved, but structural stability and durability deteriorate
Solution Approach 1:
The roller combines a rigid inner shell made of durable material with an outer layer made of resiliently deformable material such as thermoplastic elastomer. This composite structure allows the device to maintain structural integrity while providing the flexibility needed for effective tissue manipulation and spinal joint mobilization.
Solution Approach 2:
Different regions of the roller have different material properties - the inner shell provides rigid structural support while the outer deformable layer provides localized flexibility and cushioning. This spatial differentiation of material qualities allows the single device to satisfy both rigidity and flexibility requirements.
3Adaptability or versatility
If a composite structure with inner and outer rollers is used, then both rigidity and flexibility are improved, but device complexity increases
Solution Approach 1:
The inner rigid shell and outer deformable layer are combined into a single integrated roller structure that functions as one unified exercise device. This merging eliminates the need for separate components while achieving both rigidity and flexibility in a single device.
Solution Approach 2:
The roller combines a rigid inner shell made of durable material with an outer layer made of resiliently deformable material such as thermoplastic elastomer. This composite structure allows the device to maintain structural integrity while providing the flexibility needed for effective tissue manipulation and spinal joint mobilization.
