The Challenge
An automotive components manufacturer was facing severe reliability issues with their car antenna assemblies. The existing antenna spring base suffered from a dual-failure mechanism: the connecting terminals were prone to detaching under vibration, and the spring itself lacked the necessary dynamic swaying force (resilience) to withstand sustained wind resistance and mechanical shock during driving.
The Yisen Solution
To solve this complex mechanical failure, Yisen Spring initiated a comprehensive overhaul of the component, focusing on both material science and structural geometry. First, we evaluated and upgraded the raw material to a specialized high-tensile spring steel that offered superior fatigue resistance and elasticity. Second, we entirely redesigned the structural integration between the spring body and the terminal base. We introduced a customized locking coil structure that mechanically bound the terminal to the spring, eliminating reliance on weak friction fits. Furthermore, we adjusted the active coils to ensure the antenna possessed the exact flexibility required to bend under heavy aerodynamic loads and immediately snap back to its original position.
The Result
The transformation was absolute. Under extreme physical testing, the newly designed Yisen antenna spring demonstrated the perfect balance of swaying flexibility and structural rigidity. The terminal detachment issue was completely eradicated, with zero separation events occurring even under maximum stress conditions. The perfectly adapted spring base is now successfully deployed in the client's automotive antenna systems, resulting in a drastically improved product lifespan and enhanced brand reputation for our partner.
