Antenna Sheath Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna sheaths have limited small angle adjustment capabilities and require an additional insertion pin for assembly, making the process time-consuming and prone to errors due to the risk of pin loss.
Innovation Solution
The antenna sheath features a tubular member with a shaft hole and first convex teeth, and a connector with rotation shafts and second convex teeth, allowing for small angle adjustments without an insertion pin, and includes positioning ribs and grooves for large angle adjustments between 0 and 135 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an insertion pin is used to connect the tubular member and base unit, then the angle adjustment can be achieved, but the assembly process becomes time-consuming and labor-consuming
Solution Approach 1:
The patent merges the connection function and angle adjustment function into a single integrated connector structure. The connector directly connects the tubular member and base unit while providing angle adjustment capability through its internal mechanism, eliminating the need for separate insertion pins and reducing assembly steps.
Solution Approach 2:
The patent extracts the insertion pin from the assembly and replaces it with a connector that has an integrated angle adjustment mechanism. This removes the problematic component that caused time loss and potential loss during assembly while maintaining the necessary functionality.
2Ease of operation
If an insertion pin is used for angle adjustment, then the connection is established, but the risk of pin loss occurs before assembly
Solution Approach 1:
The connector integrates the angle adjustment mechanism within its structure, eliminating the separate insertion pin that could be lost. The angle adjustment is achieved through the connector's internal design, ensuring all components remain attached throughout the assembly process.
3Adaptability or versatility
If a conventional angle adjustment device is used, then large angle adjustments are possible, but small angle adjustments cannot be performed
Solution Approach 1:
The connector employs a dynamic angle adjustment mechanism that can operate in different modes. For large angle adjustments, the positioning ribs engage with positioning grooves at discrete intervals (0°, 45°, 90°, 135°). For small angle adjustments, the convex teeth on the rotation shaft provide continuous fine-tuning capability, allowing precise angular positioning in both ranges.
