Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional squat rack with pivotally connected tubes is used, then the user can perform squatting exercise, but the user's muscles in the waist and upper legs are only subject to light loads and do not exercise sufficiently
Solution Approach 1:
The squat rack employs dynamically adjustable components including an adjustable seat position, adjustable leg support angle, and adjustable handle position. These dynamic adjustments allow the exercise device to adapt to different user requirements and increase muscle engagement intensity, transforming the static conventional rack into a dynamic training system that can progressively challenge the user's waist and upper leg muscles.
Solution Approach 2:
The invention changes key parameters of the squat rack including the angle of the leg support tube, the position of the seat, and the configuration of the handle. By adjusting these parameters, the exercise trajectory and resistance distribution are modified to place greater load on the waist and upper leg muscles, thereby improving exercise effectiveness without requiring the user to increase body weight.
2Productivity
If a conventional squat rack is used, then the user can exercise, but the user exerts too much stress in the knees or upper legs and excessively wears the knees
Solution Approach 1:
The invention introduces a leg support tube with adjustable angle as an intermediary element between the user's legs and the ground. This intermediary component provides proper structural support and distributes the load more evenly, preventing excessive stress concentration on the knees. The adjustable angle allows optimization of the force distribution to protect the knees while maintaining exercise effectiveness.
Solution Approach 2:
By adjusting the angle parameter of the leg support tube and the position parameter of the seat, the invention modifies the exercise trajectory and force distribution. These parameter changes reduce harmful stress on the knees by optimizing the mechanical leverage and support during the squatting motion, allowing users to exercise with proper form and reduced joint strain.
3Ease of operation
If a conventional squat rack is used, then the user can perform squatting motion, but the user does not exercise the waist and upper legs sufficiently
Solution Approach 1:
The squat rack incorporates dynamically adjustable components that allow users to modify the exercise parameters without complicating the basic operation. The adjustable seat, leg support angle, and handle position enable users to target different muscle groups including the waist and upper legs, while maintaining the simplicity of the squatting motion. This dynamic adaptability enhances muscle engagement without sacrificing ease of use.
Solution Approach 2:
The invention integrates multiple functions into a single squat rack system, including adjustable seat positioning, adjustable leg support, and adjustable handle configuration. This multi-functionality allows the same device to effectively exercise various muscle groups including the waist and upper legs, making the device universally applicable for different training goals while maintaining operational simplicity through a unified adjustment mechanism.

AI summary
A multi-mode squat rack includes a frame, a support unit and a handle unit. The frame includes two struts pivotally connected to each other, two stepping boards connected to one of the struts, and a mount pivotally connected to the first strut. The support unit includes a seat post pivotally connected to the first strut, a seat supported on the seat post, a pair of ears supported on a side of the seat post near the first strut, at least one fin supported on an opposite side of the seat post, and an elastic unit arranged between the mount and the fin. The handle unit includes a stem pivotally connected to the first strut, a connection rod formed with an end pivotally connected to the stem and another end pivotally connected to the first strut or the pair of ears, and a handle connected to the stem.
