Shielding Device High Torque Connection via Riveted Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shielding devices fail to meet high torque specifications, particularly exceeding 41 kg-cm, as they are limited to low torque values due to the connection between the frame body and connector, which is insufficient for applications like those regulated by the Society of Cable Television Engineers (SCTE).
Innovation Solution
The shielding device design includes a frame body with multiple sideboards, one of which has a receiving hole and slots, and a connector with protrusions that are riveted or soldered into these slots to securely connect the connector to the frame body, increasing the torque value beyond 60 kg-cm, thus meeting high torque requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector is simply connected to the frame body by means of riveting, then the manufacturing process is simple, but the torque value is limited to only 30-40 kg-cm which fails to meet high torque specification
Solution Approach 1:
The connection structure is segmented into multiple components: the frame body with receiving hole, the connector with protrusions, and the rivet element. The protrusions are formed on the connector body and engage with corresponding slots in the frame body, creating a segmented connection system that distributes mechanical stress and enables higher torque transmission while maintaining manufacturing simplicity.
Solution Approach 2:
The protrusions of the connector are nested into the slots of the frame body, forming a nested connection structure. The rivet element is then inserted through the receiving hole to secure the nested protrusions in place. This nested arrangement allows the connector to be firmly embedded in the frame body, achieving high torque values over 60 kg-cm while keeping the manufacturing process straightforward.
2Strength
If manual welding is used to increase torque, then the torque value increases, but the manufacturing complexity and cost increase
Solution Approach 1:
The connector design incorporates protrusions that self-align and self-secure into the slots of the frame body through the riveting process. The rivet element automatically fastens the protrusions in place during assembly, eliminating the need for manual welding or other complex joining methods. This self-service mechanism achieves high torque values while maintaining simple manufacturing processes and reducing production complexity.
