Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed frame is used to create exercise motions in a single plane, then the machine structure is simple, but the exercise variety and muscle groups engaged are limited
Solution Approach 1:
The user support frame is made dynamically adjustable in angle relative to the stationary base frame, allowing transition between horizontal and vertical orientations. This dynamic configuration enables the same machine to provide multiple exercise planes and motion patterns without requiring multiple fixed-frame machines, thereby increasing exercise variety while maintaining a single machine structure.
Solution Approach 2:
The invention adds the angular dimension to the exercise machine by allowing the user support frame to be positioned at different angles (horizontal, vertical, and intermediate positions). This dimensional change transforms a single-plane exercise machine into a multi-plane machine, enabling exercises in various planes of motion and engaging different muscle groups without significantly complicating the overall machine structure.
2Adaptability or versatility
If a closed loop range of motion is required, then the machine provides continuous motion, but the range of motion must be adjusted to fit various size users adding components and cost
Solution Approach 1:
Instead of using adjustable components to modify the range of motion, the invention uses the dynamic angle adjustment of the user support frame to accommodate users of various sizes and capabilities. By changing the frame angle, the effective range of motion is modified without adding mechanical adjustment components, thereby maintaining simplicity while providing adaptability.
Solution Approach 2:
The invention changes the geometric parameter of the exercise path by adjusting the angle of the user support frame. This parameter change effectively modifies the range of motion and exercise characteristics without requiring physical adjustment of mechanical components, thus avoiding additional parts and cost while still accommodating various user needs.
3Ease of operation
If a circular crank is incorporated into the mechanical function, then the machine produces continuous rotational motion, but all users must follow a fixed pattern of motion that prevents control over range of motion
Solution Approach 1:
The invention extracts the circular crank mechanism from the design, replacing it with a direct reciprocating motion system. This removal eliminates the fixed rotational pattern imposed by a crank, allowing users to control the range of motion directly without being constrained by the mechanical cycle of a circular crank, thereby improving ease of operation without adding mechanical complexity.
4Adaptability or versatility
If the user is weight bearing in a standing position only, then the machine structure is simple, but the variation of muscle group engagement is limited
Solution Approach 1:
The user support frame is made dynamically adjustable in angle, allowing the user to transition between standing (vertical frame) and seated (horizontal frame) positions. This dynamic reconfiguration enables weight-bearing exercises in multiple positions, engaging different muscle groups without requiring multiple separate machines, thereby increasing versatility while maintaining a single machine structure.
Solution Approach 2:
The user support frame serves multiple functions by being adjustable to different angles, allowing it to support both standing and seated exercise positions. This multi-functionality enables a single machine structure to provide varied muscle group engagement through position changes, eliminating the need for separate machines for different exercise types.
