Solution Overview
Problem
Existing connectors for fluid circulating systems face challenges in securely and easily diverting fluid flow to auxiliary devices like filters, especially when the relative position and orientation of pipework vary and access is restricted, making it difficult to maintain a substantially vertical orientation and secure the connection.
Innovation Solution
A connector with a body having an inlet and outlet port, an auxiliary port for diverting and returning fluid, a collar with releasable locking means, and seal means to secure the connection, allowing for relative movement and rotation adjustments while maintaining a seal, even at full system pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid fixed connection is used to secure the auxiliary device, then connection strength is improved, but adaptability to different orientations and positions deteriorates
Solution Approach 1:
The connector employs a dynamic locking mechanism with two distinct states: a locked state providing strong fixed connection, and an unlocked state allowing rotation and repositioning. The resilient locking members can be released to permit adjustment of the auxiliary device orientation, then re-engaged to secure the desired position, thus providing both adaptability and strength at different operational phases
Solution Approach 2:
The connection function is segmented into two independent locking mechanisms (first and second locking means) that can operate separately. This segmentation allows one locking mechanism to be engaged while the other is disengaged, enabling controlled rotation and adjustment while maintaining partial connection strength, and full strength when both are engaged
2Reliability
If a fixed secure connection is used, then connection reliability is improved, but ease of adjustment and installation deteriorates
Solution Approach 1:
The connector transitions from a static fixed connection to a dynamic adjustable connection. The resilient locking members are designed to be easily released and re-engaged, allowing users to adjust the auxiliary device orientation or position without complex tools or procedures, then secure the connection reliably in the desired position
Solution Approach 2:
The resilient locking members are pre-positioned in grooves that guide their movement and engagement. The grooves are shaped to automatically align the locking members with engagement features on the auxiliary device, reducing the effort required for adjustment and ensuring reliable engagement without precise manual alignment
3Adaptability or versatility
If the connector allows rotation and movement, then adaptability to restricted access and varying pipework orientation is improved, but connection stability deteriorates
Solution Approach 1:
The connector provides conditional stability through its two-state locking system. When both locking means are engaged, the connection is stable and fixed. When one locking means is released, the connector becomes dynamically adjustable, allowing rotation and movement to accommodate restricted access or varying pipework orientations. The stability is restored when both locks are re-engaged in the new position
Solution Approach 2:
The stability function is segmented into two independent locking mechanisms that can be engaged separately. This allows the connector to maintain partial stability (one lock engaged) during adjustment, then achieve full stability (both locks engaged) in the final position, balancing adaptability and stability throughout the installation process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector enables secure and adjustable connections to auxiliary devices in various orientations, ensuring fluid integrity and ease of fitting without leakage, even when the auxiliary device is in a vertical orientation, facilitating installation and maintenance within fluid circulating systems.
Implementation Method 1
the first and second locking means each comprise a resilient member locatable on the collar and releasably engageable with the auxiliary device
Implementation Method 2
where in each locking means comprises a spring clip locatable in the respective groove

AI summary
A connector is provided for connecting an auxiliary device to a fluid circulating system. The connector comprises a body with inlet and outlet ports for connection to the fluid circulating system, and an auxiliary port for connection to the auxiliary device. The auxiliary port diverts fluid from the inlet to the auxiliary device and returns fluid to the outlet port. A collar surrounds the auxiliary port, secured by two spring clips. When the spring clips are both locked, movement between the connector and auxiliary device is prevented. When the first clip is released and the second clip is locked, rotation between the connector and the auxiliary device about the central axis and a predetermined amount of movement along the axis is permitted. The connector can be fitted in a variety of orientations relative to the auxiliary device and angular adjustment is possible while the two remain connected and sealed.
