Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation detecting devices with glass substrates are prone to damage from weight and impact, requiring rigid supporters that increase the device's weight and complexity.
Innovation Solution
A radiation detecting device with a flexible substrate and semiconductor elements, supported by a foam-based supporter that disperses loads and absorbs impacts, reducing the overall weight while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid supporter (fiber reinforced resin or metal) is used to support the glass substrate, then the substrate resistance to loads and impacts is improved, but the device weight increases
Solution Approach 1:
The patent applies composite materials by combining foam material (providing light weight and shock absorption) with a rigid plate (providing structural strength and substrate support). This composite structure achieves both protection of the glass substrate against impacts and loads while maintaining low device weight, resolving the contradiction between strength and weight.
Solution Approach 2:
The patent implements local quality by placing a rigid plate only at the back surface of the foam supporter where maximum structural support is needed, rather than making the entire supporter rigid. This localized rigid structure provides sufficient substrate protection while minimizing the overall weight of the device.
2Strength
If a thick supporter is used to ensure rigidity, then the substrate protection is improved, but the device weight and volume increase
Solution Approach 1:
The patent uses a composite structure combining foam material with a rigid plate to achieve the required rigidity and substrate protection without increasing the supporter thickness. The rigid plate provides the necessary structural strength while the foam provides light weight and shock absorption, eliminating the need for a thick rigid supporter.
Solution Approach 2:
The patent applies local quality by concentrating the rigid structural element (plate) only where needed for substrate support at the back surface, rather than making the entire supporter thick and rigid. This localized approach achieves the required rigidity with minimal material and weight.
