Pilates Reformer Spring Bar Adjustment From Outside the Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pilates reformers require trainers to reach between the user's legs to adjust the spring bar rod, causing discomfort and inconvenience.
Innovation Solution
A pilates reformer design with elongated rails and notches allows for external adjustment of the spring positioning rod via a handle, enabling trainers to adjust the spring support rod position externally without reaching between the user's legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spring bar rod is positioned internally within the frame, then the structural integrity and compact design are maintained, but the adjustment process becomes inconvenient and uncomfortable for the trainer and user
Solution Approach 1:
The spring bar rod adjustment mechanism transitions from internal-only adjustment to external adjustment by extending the rod through the side beams. The rod can be positioned along its entire length externally, allowing trainers to access and adjust it from outside the frame, thereby resolving the contradiction between structural compactness and adjustment convenience.
2Adaptability or versatility
If the spring bar rod is made adjustable for different exercises, then the versatility of the equipment is improved, but the complexity of positioning and securing the rod increases
Solution Approach 1:
The spring bar rod incorporates self-retaining features including engagement notches and retaining elements that automatically secure the rod at selected positions. This self-service mechanism allows for easy adjustment to different exercise configurations without requiring complex external locking systems or additional tools, thereby achieving versatility with minimal added complexity.

AI summary
Disclosed herein is an exercise machine that includes an elongated frame. The exercise machine includes a moveable carriage slidably coupled to the elongated frame. The exercise machine includes a spring support rod slidably coupled with the elongated frame and selectively positionable by a handle. The exercise machine includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the moveable carriage. The resistive member is configured to bias the moveable carriage relative to the elongated frame. The exercise machine includes a first spring positioning rod slidably coupled to and moveable within a first rail on the elongated frame and a second spring positioning rod slidably coupled to and moveable within a second rail on an opposing side of the elongated frame. The spring support rod is extends between the first and second spring positioning rods.
