Vehicle Antenna Mounting Structure With Elastic Bracket Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna devices for vehicles are bulky and costly due to the need for multiple components and inconvenient nut-based affixing methods, which complicates installation and user operation.
Innovation Solution
An antenna device design featuring a base, elastic bracket, restriction unit, and fastener, where the elastic bracket's legs guide the fastener to secure the restriction unit to the base, allowing for a compact, reduced-component structure with a bolt-based locking mechanism that can be pre-affixed to the base for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nut-based affixing method is used to secure antenna device to vehicle shell, then reliable fixation is achieved, but device complexity and number of parts increase
Solution Approach 1:
The patent integrates the fastening function directly into the antenna device base by incorporating a threaded hole, merging the antenna structure and fastening mechanism into a single integrated component. This eliminates the need for separate nuts and mounting brackets, reducing part count while maintaining secure fixation to the vehicle shell
Solution Approach 2:
The base structure serves multiple functions: it provides mechanical support for the antenna element, integrates the fastening mechanism through an embedded threaded hole, and enables direct mounting to the vehicle shell. This multi-functionality eliminates the need for separate mounting hardware
2Reliability
If conventional nut-based affixing method is used, then secure mounting is achieved, but ease of operation deteriorates due to complex installation process
Solution Approach 1:
The threaded hole for the fastener is pre-integrated into the base structure during manufacturing. This preliminary action allows the fastener to be directly screwed into the base without requiring separate mounting brackets or complex assembly steps, significantly simplifying the installation process while ensuring secure mounting
3Stability of the object's composition
If multiple components are used in antenna device structure, then structural stability is maintained, but device size increases
Solution Approach 1:
The patent combines the antenna support structure and mounting base into a single integrated base component. The threaded hole is directly formed in this integrated base, eliminating the need for separate mounting brackets and fastening components. This integration maintains structural stability while significantly reducing the overall device volume
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
This design results in a smaller, cost-effective antenna device with simplified user operation, as the fastener can be directly locked after placement on the vehicle shell, enhancing product competitiveness and user convenience.
Implementation Method 1
an elastic bracket (3), a restriction unit (4), and a fastener (5). The base (2) includes a plurality of grooves (21). The elastic bracket (3) includes a plurality of elastic legs (31). Each of the elastic legs (31) includes a free end (319). The free end (319) is guided by the corresponding groove (21). The elastic legs (31) respectively abut the restriction unit (4).
