Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna box is rotably installed with multiple equidistant connecting portions on a circumference, then the capability of adjusting left and right directions and positions is improved, but the device complexity increases
Solution Approach 1:
The fixing structure is divided into multiple discrete connecting portions (first connecting portions on the antenna box and second connecting portions on the fixing frame) arranged equidistantly on circumferences. This segmentation allows the antenna box to be rotated and fixed at multiple predetermined positions by engaging different pairs of connecting portions, thereby improving adjustment capability while maintaining a relatively simple overall structure.
Solution Approach 2:
The multiple equidistant connecting portions serve multiple functions: they enable rotation to different positions, provide fixed mounting points, and allow for both horizontal and vertical adjustment planes. This multi-functionality improves the versatility of the antenna fixing structure without requiring additional separate mechanisms for each function.
2Measurement precision
If the quantity of second connecting portions is increased (n times of first connecting portions), then the precision and breadth of directional adjustment is improved, but the manufacturing complexity increases
Solution Approach 1:
The connecting portions are segmented into two sets: first connecting portions on the antenna box and second connecting portions on the fixing frame. The second set contains n times more elements than the first set, where n is a natural number. This segmentation allows for precise positioning (with more engagement options) while keeping the manufacturing process systematic and repeatable.
Solution Approach 2:
The connecting portions are arranged equidistantly on circumferences, creating uniform local qualities throughout the structure. This uniform distribution ensures that each connecting portion provides the same positioning precision and mechanical properties, making the manufacturing process more consistent and easier to control despite the increased quantity of components.
3Reliability
If pivotal connections with friction enhancement are used between pivot blocks, then the secure coupling and stability is improved, but the ease of operation for adjustment decreases
Solution Approach 1:
The pivot blocks are designed to provide dynamic friction characteristics: sufficient friction to maintain secure coupling and stability during operation, but allowing for deliberate adjustment when force is applied. The friction-enhanced pivotal connection transitions between a locked state (for stability) and an adjustable state (when manipulation is needed), balancing reliability and ease of operation.
Applied Scientific Principles
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 structure allows for precise adjustment of antenna direction and angle, improving signal efficiency by enabling the antenna box to be rotated and fixed in various positions and angles, enhancing the capability to align with signal directions effectively.
Implementation Method 1
A rib between the first pivot block and the second pivot block is provided to increase the friction between the first pivot block and the second pivot block and further pivotally coupling and combining the first pivot block and the second pivot block more securely

AI summary
An antenna fixing structure includes an antenna box and a fixing frame. The antenna box includes a casing with a first circumference defined by a first center and a first radius, and the casing has equidistant first connecting portions disposed along the first circumference. The fixing frame includes a carrying board with a second circumference defined by a second center and a second radius, and the carrying board has equidistant second connecting portions disposed along the second circumference, so that the first connecting portions and the second connecting portions can be rotably installed with respect to the first and second centers and coupled to each other. Therefore, the antenna box can be rotated to a predetermined position and then fixed to the fixing frame, and the antenna fixing structure has the effect of adjusting the direction, position or angle of an antenna.
