Modular Exercise Bench With Anti-Tilt Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise equipment is limited in its ability to perform a wide range of basic movements, such as pushing, pulling, hinge, lunging, and squatting, requiring multiple devices and occupying significant space, while existing benches are inefficient for supporting these movements.
Innovation Solution
A modular exercise bench with adjustable bar assemblies and anti-tilt mechanisms that allow for various orientations and attachments, enabling a broader range of exercises, including pull-ups, triceps dips, squats, and lunges, while preventing the bench from tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate exercise devices are used to cover all basic movements, then exercise variety is improved, but space occupation and device complexity increase
Solution Approach 1:
The bench is designed with multiple bar slot assemblies positioned at different locations and orientations, allowing a single bench to support various exercises including pull-ups, triceps dips, squats, and lunges. The bar assemblies can be inserted into slots at different orientations to enable different movement patterns, making one piece of equipment replace multiple separate exercise devices.
Solution Approach 2:
The bench structure is divided into multiple functional zones with separate bar slot assemblies located at different positions (front, rear, sides) of the bench. This segmentation allows each zone to support specific exercise types while maintaining a compact integrated structure that saves space compared to separate full-size exercise machines.
2Adaptability or versatility
If bars are made adjustable with multiple orientations, then adaptability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The bar assemblies are designed to be adjustable and repositionable within the bar slots, allowing users to change bar orientations and positions dynamically based on exercise requirements. The slots accommodate bars in multiple orientations (horizontal, vertical, angled) and at different locations along the bench, providing dynamic adaptability without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
Instead of making the bars themselves complex and adjustable, the invention inverts the approach by providing multiple fixed slots at different orientations and positions in the bench structure. The bars remain simple and uniform, while the slots provide the adjustability and orientation variety, simplifying bar manufacturing while achieving the same versatility.
3Adaptability or versatility
If the bench structure is extended to support more exercises, then exercise capacity is improved, but stability and tipping resistance worsen
Solution Approach 1:
The bench includes an anti-tilt assembly with counterweight elements positioned to offset the tipping forces generated during exercises. The anti-tilt mechanism uses weight distribution and mechanical leverage to prevent the bench from tipping when users perform movements that create rotational forces, such as pull-ups or squats with bar attachments.
Solution Approach 2:
The anti-tilt assembly introduces a new dimension of stability control by adding a mechanical counterbalance system that operates independently from the basic bench structure. This additional dimensional element (the anti-tilt mechanism) provides stability without requiring the main bench structure to be overly bulky or heavy.
