Twist Clip Fastening for Hydronic Fin-to-Conduit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of heat-radiating fins in hydronic heating systems is time-consuming and labor-intensive due to the need for multiple rivets, making it a tedious task.
Innovation Solution
A twist clip is used to quickly and easily attach heat-radiating fins to conduits, featuring an upper and lower gripping member connected by an upright support and a handle for manual twisting, allowing the fin and conduit to be clipped together, providing a cost-effective alternative to riveting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rivets are used to attach fins to conduits, then the attachment is strong and reliable, but the installation process becomes time-consuming and labor-intensive
Solution Approach 1:
The invention extracts the fastening function from multiple rivets and concentrates it into a single twist clip mechanism. The clip is inserted through pre-pierced holes and then twisted to secure the fin to the conduit, eliminating the need for multiple separate riveting operations while maintaining attachment reliability.
Solution Approach 2:
The twist clip acts as an intermediary device that simplifies the connection process. Instead of directly riveting the fin to the conduit with multiple fasteners, the clip serves as a mediating component that can be easily inserted and twisted into place, bridging the fin and conduit together in a single operation.
2Strength
If multiple rivets are used to secure fins, then the connection is durable, but the number of installation steps increases
Solution Approach 1:
The invention merges the functions of multiple rivets into a single twist clip component. The clip incorporates both the fastening and securing functions that would otherwise require multiple separate rivets, thereby reducing installation complexity while maintaining connection strength through the twisting action that firmly attaches the fin to the conduit.
3Ease of manufacture
If a simple clip design is used, then manufacturing is easier and cheaper, but the attachment may not be as secure
Solution Approach 1:
The twist clip utilizes dynamic action through rotation to achieve secure attachment. The simple clip design is transformed from a static component into a dynamic fastening mechanism where the twisting motion engages the clip's geometry to firmly secure the fin to the conduit, thereby achieving reliable attachment without complex manufacturing.

AI summary
A twist clip for attaching a heat-radiating fin to a conduit of a hydronic heating system includes an upper gripping member, a lower gripping member connected to the upper member by an upright support member, and a handle portion looping downwardly from the lower gripping member to enable a user to hold the clip and to manually twist the clip to cause the upper and lower gripping members to rotate relative to the fin and conduit such that the fin and conduit are clipped together. This twist clip enables quick and easy attachment of fins to conduits, which greatly reduces the time and effort required to install a hydronic heating system.
