Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional friction-based pivotable connection structure is used, then the antenna can be pivotally turned, but the friction decreases over time causing the antenna to become loose and unstable
Solution Approach 1:
The pivotable connection is divided into multiple independent pivot points (first pivot point and second pivot point) with separate friction control mechanisms. Each pivot point has its own frictional force control unit, allowing independent adjustment and maintenance of friction levels, preventing the degradation issue from affecting the entire connection system.
Solution Approach 2:
The invention introduces adjustable friction parameters through friction control units that can modify the frictional force at each pivot point. By changing the friction parameter dynamically or through selective engagement of friction elements, the system maintains optimal positioning stability throughout its service life without the friction continuously degrading.
2Adaptability or versatility
If simple pivotable connection structure is used, then the device complexity is low, but the degrees of freedom are limited preventing adjustment within wide range of angles
Solution Approach 1:
The connection structure is segmented into multiple pivot points (first pivot point for vertical adjustment, second pivot point for horizontal adjustment) with distinct functions. This segmentation enables multi-directional pivoting capabilities while keeping each individual pivot mechanism relatively simple and manageable.
Solution Approach 2:
The pivotable connection structure serves multiple functions: it provides vertical pivoting through the first pivot point, horizontal pivoting through the second pivot point, and maintains positioning stability through friction control. This multi-functionality achieves wide adaptability without proportionally increasing complexity.
3Ease of operation
If friction-based pivotable connection is used, then the antenna can be held in position, but the friction decreases over time requiring frequent repositioning or device movement
Solution Approach 1:
The friction parameter is made adjustable through friction control units that can modify the frictional force at each pivot point. This allows the system to maintain optimal positioning accuracy throughout its service life by compensating for friction degradation, eliminating the need for frequent repositioning.
Solution Approach 2:
The friction control units enable the system to self-adjust and maintain optimal friction levels at each pivot point, compensating for wear and degradation automatically. This self-service capability maintains positioning accuracy without requiring external intervention or device movement.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides high degrees of freedom for antenna positioning, maintaining stability and allowing for easy adjustment to various angles, eliminating the need for frequent device reorientation.
Implementation Method 1
a first friction section is provided on the outer wall surface of the pivot post at a predetermined position; a second friction section is provided on a wall surface of the pivot base surrounding the axial opening for engaging with the first friction section on the pivot post
Implementation Method 2
The limiting recess includes a raised limiting portion for stopping the stopper from moving any further when the pivot post is pivotally turned clockwise or counterclockwise, so as to define a maximum range of angles within which the pivot device can be pivotally turned relative to the pivot base
Implementation Method 3
The pivot block has a top portion pivotally turnably received in the holding space defined between the antenna case and the holding plate for the holding plate to bear thereon

AI summary
A multi-directional pivoting antenna includes an antenna case, a pivotal device, and a pivot base. The antenna case is pivotally connected to the pivotal device and can be vertically turned relative to the pivotal device, and the pivotal device is fitted in the pivot base and can be horizontally turned relative to the pivot base. Therefore, when the pivot base of the pivoting antenna is mounted on an electronic device for wireless signal transmission, the pivotal device and the pivot base provide the pivoting antenna with high degrees of freedom, allowing the antenna case to be pivotally turned horizontally and vertically to different angular positions and directions, and making the pivoting antenna very convenient to use.
