Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structures for reducing sloshing noises in liquids containers for motor vehicles, with random arrangements of interlinked threads, are prone to disintegration due to thermal stress during the blow-molding process, leading to reduced damping properties and potential malfunctions in valves and sensors.
Innovation Solution
A structure with a random arrangement of interlinked threads, where multiple threads are connected in a materially integral manner, featuring a planar cover to shield against blower air and prevent disintegration, and produced using an extrusion device and post-processing installations for forming a monolithic and heat-resistant structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a random arrangement of mutually interlinked threads is used to reduce sloshing noises, then damping properties become directionally independent, but the structure is prone to disintegration under thermal stress during blow-molding
Solution Approach 1:
The structure is divided into multiple individual threads that are mutually interlinked in a random arrangement, allowing each thread to independently absorb thermal stress while maintaining overall structural integrity and directionally independent damping properties
Solution Approach 2:
The structure combines multiple threads with different material properties or configurations to create a composite structure that maintains both damping effectiveness and thermal resistance during the blow-molding process
2Ease of manufacture
If the structure is exposed to hot blower air during blow-molding, then the plasticized wall can be formed, but reflected blower air causes localized disintegration of the structure
Solution Approach 1:
The threads are pre-connected in a materially integral manner before exposure to thermal stress, creating a robust network that can withstand the thermal onslaught of reflected blower air during the blow-molding process without localized disintegration
Solution Approach 2:
The random arrangement of mutually interlinked threads creates a cushioning effect that distributes thermal stress uniformly across the structure, preventing localized overheating and disintegration during exposure to hot blower air
3Stability of the object's composition
If threads are materially integral connected to form a monolithic structure, then structural integrity is improved, but manufacturing complexity increases
Solution Approach 1:
The threads are designed to automatically interlink and connect in a materially integral manner through their own physical or chemical properties during the manufacturing process, forming a monolithic structure without requiring complex external joining mechanisms or additional processing steps
