Telescopic Exercise Device With Internal Air Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices fail to provide a rigid, self-contained, and compact design with reliable means of extension and contraction, internal damping, and consistent resistance for promoting improved posture and muscle strength, as they often flex during use or lack effective resistance mechanisms.
Innovation Solution
A self-contained exercise device comprising a lightweight, rigid center tube with two surrounding shorter tubes forming handles, featuring an elastic resistance member housed within the center tube and air metering for engagement of muscles, with low friction bushings and end stoppers for alignment and smooth motion, allowing for dynamic length adjustment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general stick type exercise devices are used, then they provide basic exercise functionality, but they fail to provide reliable means of extension and contraction and may flex during use
Solution Approach 1:
The device is divided into three telescopic tubes arranged in a triangular configuration, where each tube can independently extend and contract. This segmentation allows reliable means of extension and contraction while maintaining rigidity through the distributed triangular structure that prevents flexing during use.
Solution Approach 2:
The device employs different properties at different locations: the central tube has a different material composition or structural characteristic compared to the outer tubes, creating localized differences in rigidity and elasticity. This local quality variation enables the device to maintain overall rigidity while allowing controlled extension and contraction movements.
2Volume of moving object
If springs are placed external to the central tube, then the structure is simpler, but the device lacks compact storage capability
Solution Approach 1:
The device uses nested telescopic tubes where the outer tubes slide within the central tube and vice versa. This nesting arrangement enables compact storage when the tubes are retracted while maintaining sufficient internal space for resilient members and mechanical components during extended use.
Solution Approach 2:
The device transitions between dynamic extended and retracted states through the telescopic mechanism. The tubes can extend for exercise and contract for storage, providing adaptability between operational and storage configurations without requiring separate structures for each function.
3Adaptability or versatility
If handles are in discreet positions, then the structure is simpler, but the device lacks adaptability for different grip options
Solution Approach 1:
The handles are designed with multi-functionality, allowing users to grip the device at multiple positions along the telescopic tubes rather than fixed locations. This universal handle design provides adaptability for different exercise requirements and user preferences while using a single continuous handle structure rather than multiple discrete components.
