One-Side Antenna Mounting Bolt Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna mounting methods require alignment and orientation of antennas, are difficult to secure with one person, and often involve multiple loose parts, leading to inefficiencies and increased costs in serial production, especially in vehicle installations where safety and precision are concerns.
Innovation Solution
An antenna unit with a design that allows mounting from one side of the mounting surface, utilizing a bolt member with a threaded or non-threaded hole and an attachment member that can be manipulated to secure the antenna unit in place without loose parts, using a tool to ensure secure fastening and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional antenna mounting methods are used with round holes and bolts, then the antenna can be securely fastened, but the antenna needs to be aligned and oriented, and the fitting requires two persons or two-directional operation
Solution Approach 1:
The patent inverts the traditional mounting approach by providing an antenna mount with a threaded hole that receives a bolt from the same side (first side) where the antenna is accessed. This eliminates the need for two-directional operation and alignment, as the bolt is manipulated from the front rather than requiring access from the underside of the mounting surface.
Solution Approach 2:
The patent extracts the threading function from the mounting surface itself and relocates it to the antenna mount. The threaded hole is provided in the antenna mount rather than requiring threaded holes in the mounting surface, thereby simplifying the mounting procedure and eliminating the need for complex alignment and orientation.
2Adaptability or versatility
If adapter rings are used to adapt the bolt to the hole dimension, then the mounting can be performed, but the alignment and orientation requirements increase the complexity and time required
Solution Approach 1:
The patent merges the adapter ring function into the antenna mount itself. The antenna mount integrates the threaded hole and mounting structure into a single component that directly receives the bolt, eliminating the need for separate adapter rings and reducing the number of parts that need to be assembled and aligned.
3Strength
If the antenna is mounted from two directions with nut and bolt, then secure fastening is achieved, but the fitting requires two persons which is not cost-effective in serial production
Solution Approach 1:
The patent inverts the mounting direction by providing a threaded hole in the antenna mount that receives a bolt from the same side where the antenna is accessed. This allows a single person to perform the entire mounting operation from the front, eliminating the need for two-person teamwork while maintaining secure fastening through the threaded connection.
4Ease of operation
If adhesive/tape mounting is used for shark fins, then single-person installation is possible, but the surface must be cleaned, alignment is required, and dismounting is difficult
Solution Approach 1:
The patent replaces the adhesive/tape mechanical bonding system with a threaded mechanical fastening system. The bolt and threaded hole provide a reversible mechanical connection that is easy to install and remove, eliminating the need for surface cleaning and alignment requirements associated with adhesive mounting while enabling easy disassembly for repair or replacement.

AI summary
The present invention relates to an antenna unit (10) for mounting on a mounting surface from a first side of the mounting surface. The antenna unit (10) comprises an element (12) comprising a first side (14) abutting against the mounting surface when the antenna unit (10) is mounted, and a second side (16) arranged parallel to and opposite the first side (14). The antenna unit (10) comprises an antenna mount (18) comprising an attachment member (22) in turn comprising a threaded hole (20) in which a bolt member (24) is applied. The bolt member (24) is manipulated by a tool (26) from the first side of the mounting surface. In a first end position of the attachment member (22), the same is applicable through a hole intended therefor in the mounting surface. In a second end position, when the bolt member (24) has been tightened by the tool (26), the attachment member (22) presses/clamps the antenna unit (10) against the first side of the mounting surface.
