Solution Overview
Problem
Existing radiosondes have a low recovery rate due to lack of recovery efforts, resulting in environmental pollution from non-biodegradable components.
Innovation Solution
A radiosonde design featuring a 'housing-in-housing' structure with biodegradable materials for the housings and components, including a printed circuit board protected by a second housing with protrusions forming air pockets for thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If non-biodegradable materials are used for housing and components, then structural strength and durability are improved, but environmental pollution increases and recovery rate decreases
Solution Approach 1:
The patent changes the material parameter from non-biodegradable to biodegradable materials for the housing and components. This parameter change allows the radiosonde to maintain sufficient structural strength during operation while enabling natural decomposition after use, thereby eliminating long-term environmental pollution and improving recovery rate through biodegradation.
Solution Approach 2:
The patent employs composite material structures where biodegradable materials are combined with protective features such as protrusions forming air pockets. This composite approach maintains structural integrity and provides thermal insulation while using environmentally friendly materials that can decompose naturally, resolving the contradiction between strength and environmental harm.
2Object-generated harmful factors
If biodegradable materials are used for housings, then environmental impact is reduced, but thermal insulation and water protection are worsened
Solution Approach 1:
The patent segments the housing structure by adding protrusions that create discrete air pockets between the biodegradable housing layers. This segmentation provides thermal insulation and water protection barriers while maintaining the biodegradable material composition, thus protecting against environmental factors without compromising the eco-friendly material choice.
Solution Approach 2:
The air pockets formed by the protrusions act as intermediary elements between the biodegradable housing and the external environment. These air pockets provide thermal insulation and water protection, mediating the interaction between the biodegradable materials and harsh environmental conditions, thereby enabling the use of biodegradable materials while maintaining protection against thermal and water hazards.
3Object-affected harmful factors
If a housing-in-housing structure with protrusions is added, then thermal insulation and water protection are improved, but device complexity increases
Solution Approach 1:
The patent implements a nested housing structure where a second housing is placed within the first housing, with protrusions on the inner surface of the first housing or outer surface of the second housing forming air pockets. This nesting approach provides thermal insulation and water protection in a compact configuration, minimizing the increase in device complexity while achieving the desired protective functions.
