Double Ended Exercise Device With Adjustable Elastic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices are limited in portability, adjustability, and versatility, making it difficult for users to perform full-body Pilates exercises at home or while traveling, and they cannot effectively mimic gym equipment like cable column weight systems or cadillac exercises.
Innovation Solution
A portable exercise device with a handle, double loop/door attachment, and adjustable elastic resistance member, which can be adjusted at both ends using a triglide slide, allowing for various exercises and resistance levels, and featuring anti-skid material and elastic loops to prevent slippage and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reformer or cadillac is used for Pilates exercises, then exercise effectiveness is improved, but weight and size make it impossible for home use and travel
Solution Approach 1:
The patent divides the large reformer/cadillac equipment into separate functional components: a portable resistance member with specific gravity markers, foot straps with D-rings, and door jamb attachment mechanisms. This segmentation allows users to achieve full-body Pilates exercises using only these portable parts rather than the entire large equipment system.
Solution Approach 2:
The patent creates a simplified copy of the reformer/cadillac functionality using portable elements. The resistance member with gravity markers replicates the resistance mechanism, while the door jamb attachment and foot straps replicate the positioning and resistance application of the original equipment, enabling the same exercises in a portable format.
2Adaptability or versatility
If a cable column weight system is used for gym exercises, then exercise versatility is improved, but weight and size make it difficult for home use and travel
Solution Approach 1:
The resistance member is designed to serve multiple functions: it provides resistance for strength training, uses gravity markers to indicate proper tension levels, can be attached to door jambs for various exercise positions, and works for both upper and lower body exercises. This multi-functionality replaces the need for multiple separate gym equipment pieces.
3Weight of moving object
If a portable exercise device without door attachment is used, then portability is improved, but the number of reformer and cadillac exercises that can be done is limited
Solution Approach 1:
The door jamb serves as an intermediary anchoring point that enables a wide variety of exercises. The D-ring attachment mechanism allows the resistance member to be securely fixed to the door jamb at different heights and positions, creating stable anchor points for pulling, pushing, and resisting exercises that mimic reformer and cadillac movements.
4Device complexity
If a non-adjustable foot loop is used, then device simplicity is improved, but the foot loop will fall off causing interruption and irritation
Solution Approach 1:
The foot loop transitions from a static, fixed design to a dynamic, adjustable system. The D-ring allows the foot strap length to be adjusted by moving the D-ring to different positions along the strap, enabling the loop to adapt to different foot sizes and exercise positions, thereby preventing it from falling off during movement.
5Device complexity
If a device without adjustable resistance is used, then device simplicity is improved, but resistance levels are limited and exercise options are significantly limited
Solution Approach 1:
The resistance level is controlled by changing the parameter of resistance member length. The specific gravity markers on the resistance member indicate different length settings that correspond to different resistance levels. Users can adjust the effective length of the resistance member by how much it is extended or retracted, providing variable resistance without complex adjustment mechanisms.

AI summary
A portable full body exercise device is described. The device can be affixed inside a door jamb from either end to perform a variety of exercises and can also be used to exercise free of a door on a chair, bed, or mat. This versatile device is comprised of a handle at one end, an elastic membrane (middle portion), and a double loop/door attachment end. The design of the device allows the resistance of the elastic membrane to be altered from both ends, allowing more or less resistance to be achieved by altering the elastic membrane's overall length.
