Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing antenna systems require a multitude of specialized brackets for different parasitic units, leading to increased manufacturing and installation costs due to the need for mono-functional brackets that can only mount specific types of parasitic units.

Innovation Solution

A modular bracket design that incorporates both PCB and isolation needle mounting mechanisms, allowing for the simultaneous mounting of various parasitic units, thereby reducing the need for multiple brackets and simplifying the design and assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple specialized brackets are used for different parasitic units, then each parasitic unit can be mounted correctly, but the number of parts increases and manufacturing costs increase

Engineering Contradiction:

Improvemounting capability for different parasitic unitsVSAvoidnumber of different brackets required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket is designed with multiple mounting mechanisms that can accommodate different types of parasitic units (PCB-based and isolation needle types) using a single unified structure. The bracket body includes first and second mounting mechanisms with different clamping structures that can be selectively used depending on the parasitic unit type, eliminating the need for multiple specialized brackets.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple specialized brackets are used for different parasitic units, then each parasitic unit can be mounted correctly, but manufacturing and installation costs increase

Engineering Contradiction:

Improvemounting capability for different parasitic unitsVSAvoidmanufacturing and installation cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By designing a single bracket that can mount both PCB-based and isolation needle parasitic units, the manufacturing cost is reduced through standardization of the bracket body and mounting mechanisms. Installation cost is reduced by eliminating the need to select and handle multiple different bracket types during assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If different brackets are required for different parasitic units, then proper mounting is achieved, but the design and manufacturing process becomes more complex

Engineering Contradiction:

Improveproper mounting of parasitic unitsVSAvoiddesign and manufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bracket is segmented into distinct mounting mechanisms (first and second mounting mechanisms with different clamping structures) that can be selectively engaged depending on the parasitic unit type. This segmentation allows each mounting mechanism to be optimized for its specific function while being integrated into a single unified bracket structure, maintaining reliability without requiring multiple complete bracket designs.

Inventive Principle:

Principle #1Segmentation

AI summary

A bracket comprises: a bracket body, at least one PCB mounting mechanism and at least one isolation needle mounting mechanism. The PCB mounting mechanism is disposed on the bracket body, for mounting a PCB parasitic unit, and the isolation needle mounting mechanism is disposed on the bracket body, for mounting the isolation needle parasitic unit. The bracket is capable of mounting different types of parasitic units.
