Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional shield connection clamp is used, then the cable shield can be connected to the shield bar, but complex assembly work is required
Solution Approach 1:
The clamp is divided into distinct functional segments: the U-shaped bracket for cable insertion, the elastic element for applying pressure, and the closure means for securing the shield bar. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process while maintaining connection integrity.
Solution Approach 2:
The elastic element automatically applies the necessary pressure force to press the cable shield against the shield bar without requiring additional fastening operations. The closure means with its guide means and elongated holes enables self-aligning assembly that guides the shield bar into position and secures it through a simple sliding motion, eliminating complex assembly steps.
2Productivity
If multiple cables are clamped simultaneously, then productivity increases, but the clamping force distribution becomes difficult to control
Solution Approach 1:
The elastic element provides a constant pressure force that automatically adapts to the number and size of cables being clamped. When multiple cables are inserted, the elastic element compresses to the same degree, distributing pressure evenly across all cables and the shield bar, ensuring consistent electrical contact regardless of cable quantity or configuration.
Solution Approach 2:
The closure means is designed with mobility along the guide means, allowing it to dynamically adjust its position as cables are inserted or removed. The elongated holes accommodate variations in cable arrangement, enabling the closure means to maintain proper clamping force distribution whether one or multiple cables are being connected simultaneously.
