High-Frequency Device Fastening with Anti-Loss Screw and Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency devices, such as impedance converters or amplifiers, face issues with precise alignment and secure fastening during installation due to potential misalignment and loss of fastening components during storage and transport, leading to unnecessary manipulations and increased risk of component loss.
Innovation Solution
Incorporating an anti-loss device for the screw, which allows rotation during assembly while securing it to the housing, and a specially designed stop and counter-holder system that fixes the counter-holder in a defined position, ensuring alignment and secure fastening without additional manipulations during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the counter-holder is freely movable on the screw during storage and transport, then the assembly process is simple, but the counter-holder may become misaligned or detached, requiring additional manipulations
Solution Approach 1:
The stop is pre-configured on the housing at a position that automatically aligns the counter-holder with the opening in the body panel when the device is installed. This preliminary positioning action eliminates the need for manual alignment during assembly, while the stop continuously maintains alignment during storage and transport.
Solution Approach 2:
The stop acts as an intermediary element between the counter-holder and the housing, providing a mechanical reference that ensures proper alignment. The stop mediates the relationship between these components, preventing misalignment without requiring complex fastening mechanisms.
2Stability of the object's composition
If the screw is securely fastened to the housing, then the assembly is stable, but the screw may become detached during storage and transport
Solution Approach 1:
The screw is nested within the counter-holder, which itself is positioned relative to the housing by the stop. This nested arrangement ensures that the screw remains secured to the housing through the counter-holder, preventing detachment during storage and transport while maintaining assembly stability.
3Manufacturing precision
If additional alignment manipulations are performed during installation, then the device can be precisely positioned, but the installation time and complexity increase
Solution Approach 1:
The stop is pre-positioned on the housing to automatically align the counter-holder with the body panel opening during installation. This preliminary alignment action eliminates the need for additional manual positioning manipulations, achieving both precise device positioning and rapid installation.
Solution Approach 2:
The stop and counter-holder arrangement enables the device to self-align during installation. The mechanical features automatically guide the counter-holder into the correct position relative to the opening, making the alignment process self-performing without requiring external manipulation.
