Antenna Array Device Integrated Molding Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna devices face prolonged production processes and tolerance accumulation due to the need for multiple components and spacers during assembly.
Innovation Solution
The antenna array device incorporates a substrate with channel holes and a molding support with stands and connection portions, reducing the number of components to be assembled by integrating the stands and spacers directly into the substrate, thereby shortening the production process and minimizing tolerance accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple spacers and components are used to separate and assemble antenna units, then the antenna units can be properly positioned and separated, but the production process is prolonged and tolerance accumulation occurs
Solution Approach 1:
The support structure is merged with the substrate to form an integrated one-piece component. The stands that were previously separate spacer components are now integrally formed on the substrate, eliminating the need for separate spacer parts and reducing assembly steps while maintaining positioning precision.
Solution Approach 2:
The stands are pre-formed on the substrate during substrate manufacturing, before the antenna units are assembled. This preliminary formation of support structures eliminates the need for separate spacer installation steps during assembly, reducing both time and tolerance accumulation.
2Adaptability or versatility
If multiple separate components (spacers, stands, antenna units) are assembled together, then the antenna array device can be constructed with modular units, but the number of assembly steps increases and production time is prolonged
Solution Approach 1:
Multiple components (substrate, support structure, stands) are merged into a single integrated antenna unit. This reduces the number of separate parts that need to be assembled while maintaining the modular nature of the antenna units themselves, allowing quick assembly of the overall array device.
Solution Approach 2:
The integrated antenna unit serves multiple functions: the substrate provides structural support, the stands provide positioning and separation, and the antenna elements provide radiation. This multi-functionality in a single integrated unit reduces the number of separate components needed.
3Strength
If multiple separate components are assembled with connection portions, then the antenna units can be securely connected, but the complexity of assembly and tolerance accumulation increase
Solution Approach 1:
The connection portions are merged into the substrate as integral features rather than separate components. This simplifies the assembly process by reducing the number of parts that need to be connected while maintaining secure mechanical connections between antenna units.
