Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting structures for micro-machined coaxial components fail to facilitate the stacking of multiple layers and access to both sides of a particular layer, lacking mechanical integrity and complicating the fabrication process.
Innovation Solution
A three-dimensional matrix system comprising metallic sheets with access holes and metal posts that maintain mechanical strength while allowing access to the lower surface, featuring a periodic pattern of holes and posts to support coaxial transmission lines and enable stacking without additional complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If components are adhered to a substrate for support, then mechanical strength is improved, but access to the lower surface is blocked and stacking is prevented
Solution Approach 1:
The substrate is segmented into a grid pattern with holes that allow access to the lower surface of components. The substrate is divided into multiple functional zones: support areas and access areas, enabling both mechanical strength and accessibility simultaneously.
Solution Approach 2:
A grid pattern acts as an intermediary structure between the substrate and the components. The grid provides mechanical support while its open structure allows access to the lower surface, mediating between the conflicting requirements of strength and accessibility.
2Strength
If components are adhered to a substrate for support, then mechanical strength is improved, but stacking of multiple layers is prevented
Solution Approach 1:
The substrate is segmented into a grid pattern with holes that allow access to the lower surface of components. The substrate is divided into multiple functional zones: support areas and access areas, enabling both mechanical strength and accessibility simultaneously.
Solution Approach 2:
The grid pattern introduces a dimensional aspect to the substrate structure. By creating a two-dimensional grid with vertical holes, the substrate provides support in the horizontal plane while allowing access and stacking in the vertical dimension.
3Stability of the object's composition
If a substrate is used to secure components, then mechanical integrity is improved, but fabrication complexity increases
Solution Approach 1:
The grid substrate serves multiple functions simultaneously: it provides mechanical support, defines component positions, enables access to lower surfaces, and facilitates stacking. This multi-functionality reduces the need for additional components and simplifies the overall fabrication process.
Solution Approach 2:
The grid pattern creates a homogeneous structure with uniform spacing and identical cell structures throughout the substrate. This homogeneity simplifies manufacturing processes and ensures consistent mechanical properties across the entire substrate surface.
