Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connectors are used to connect harness straps, then the harness provides basic connectivity, but the straps tend to tangle and the connectors are difficult to quickly connect and disconnect
Solution Approach 1:
The connector is divided into multiple body components (first body component, second body component, third body component) that can independently rotate about the longitudinal axis of the rod. This segmentation allows each component to move independently, preventing tangling while maintaining connection functionality.
Solution Approach 2:
The connector components are designed to be dynamically movable rather than fixed. Each body component can rotate independently about the rod's longitudinal axis, providing adaptive movement that prevents strap tangling while enabling quick connection and disconnection operations.
2Adaptability or versatility
If fixed connector components are used, then the structure is simple, but the harness cannot adapt to user movement and causes discomfort
Solution Approach 1:
The connector components are designed with rotational freedom about the rod's longitudinal axis, allowing them to adapt dynamically to user movement. This dynamic capability enables the harness to accommodate various body positions and movements while maintaining connection integrity.
Solution Approach 2:
Multiple body components are merged into a single connector assembly that shares a common rod, allowing them to move independently while remaining functionally integrated. This combination provides both adaptability through independent movement and structural coherence through the shared rod.
3Reliability
If simple connectors are used, then the harness can be manufactured easily, but safety compliance and redundant safety mechanisms are insufficient
Solution Approach 1:
The connector is segmented into multiple body components that can independently rotate, creating redundant movement paths that enhance safety compliance. This segmentation allows the harness to maintain connection integrity even if one component encounters resistance, while remaining manufacturable through modular assembly.
Solution Approach 2:
The connector design changes the degree of freedom parameter by allowing independent rotation of each body component about the rod's longitudinal axis. This parameter change enhances safety and compliance by providing multiple independent movement paths while maintaining ease of manufacture through standardized rotational joints.

AI summary
A connection arrangement for use with a wearable body harness includes a first connector having a first body component, a second body component, and an attachment element connected to each other by a rod having a longitudinal axis. The connection arrangement further includes a second connector removably connectable to the first connector. Each of the first body component, the second body component, and the attachment element are independently movable relative to each other about the longitudinal axis of the rod. The first connector and the second connector are removably connectable to each other via a locking and release mechanism between a first, locked configuration, where the first connector and the second connector are connected to each other, and a second, unlocked configuration, where the first connector and the second connector are disconnected from each other.
