Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional abdominal rollers are limited in functionality, uncomfortable for users, and complex to manufacture, lacking in providing adequate support and versatility for various exercises and massages.
Innovation Solution
An exercise roller with a cylindrical core and a foam cover featuring a repeating pattern, supported by a metal bar with grip handles, allowing for increased comfort, support, and modular functionality, including the integration of additional components for enhanced exercises and massages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional abdominal rollers are used, then the basic rolling function is provided, but the functionality is limited and comfort is poor
Solution Approach 1:
The roller is divided into distinct functional segments: a hard cylindrical core for structural support and rolling function, a foam cover for comfort and massage, and removable brackets for additional functionality. Each segment serves specific purposes that can be independently optimized.
Solution Approach 2:
The roller combines different materials with complementary properties: a hard core material (metal or plastic) for durability and rolling performance, and a soft foam material for comfort and therapeutic massage, creating a composite structure that provides both hard support and soft cushioning.
2Device complexity
If conventional abdominal rollers are used, then the basic structure is simple, but the manufacturing process is complex
Solution Approach 1:
The foam cover is integrated directly onto the core through overmolding, combining two components into a single manufacturing operation. The grip handles are also integrated with the bar structure, reducing the number of separate parts and assembly steps.
Solution Approach 2:
The bar serves multiple functions: it provides structural support, serves as an axis for the core to rotate on, and includes integrated grip handles for user control. This multi-functionality reduces the need for separate components.
3Strength
If the cylindrical core extends the entire length between grip handles, then the core is directly adjacent the handles providing support, but the device may be less comfortable for some users
Solution Approach 1:
The roller provides different qualities at different locations: the core provides hard structural support and rolling stability, while the foam cover provides soft cushioning and comfort. The grip handles at the ends provide additional hard support points for user control, creating a gradient of support qualities along the length of the roller.
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
The exercise roller provides improved comfort and support, reduces the risk of injuries like shin splints, and increases functionality by enabling a range of exercises and massages while simplifying the manufacturing process.
Implementation Method 1
the material of the foam cover, and the density of the inner core and the foam... the exercise roller is configured to provide improved comfort and support during rolling
Implementation Method 2
The cover of the exercise roller may be formed of closed-cell foam material
