Cross-linked Resin Cover for Sensor Device Damage Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sensor devices face challenges in resisting external damage, particularly in severe environments, where existing technologies do not adequately enhance their durability and resistance to physical and thermal stress.
Innovation Solution
A sensor device is designed with a resin cover part that includes at least a portion of its surface cross-linked, either through electron beam cross-linking or chemical cross-linking, to improve resistance to external damage. This cross-linked surface is harder and maintains its integrity even at high temperatures, preventing damage from external factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor device is exposed to severe environments, then the durability and resistance to external damage need to be improved, but the complexity of the device structure increases
Solution Approach 1:
The patent applies parameter changes by cross-linking the resin cover part to transform its physical and chemical properties. The cross-linking process modifies the molecular structure of the resin, increasing its hardness, heat resistance, and overall durability without adding complex structural components. This allows the sensor device to withstand severe environments including high temperatures and physical impacts while maintaining a simple integrated structure.
Solution Approach 2:
The patent utilizes composite materials by creating a cross-linked resin structure that combines the protective functions of multiple materials into a single integrated cover part. The cross-linked resin exhibits enhanced properties similar to combining multiple protective layers, providing hardness, heat resistance, and impact absorption simultaneously, thereby improving reliability without increasing structural complexity.
2Temperature
If electron beam cross-linking is applied to the resin cover part, then the heat resistance and hardness are improved, but the manufacturing process complexity increases
Solution Approach 1:
The patent applies preliminary action by incorporating a cross-linking agent into the resin composition before molding. This preliminary preparation ensures that the resin has the necessary cross-linking capability built-in, allowing subsequent electron beam irradiation to efficiently induce cross-linking and achieve the desired heat resistance and hardness without requiring complex post-processing steps or multiple manufacturing stages.
3Strength
If the resin cover part is made harder through cross-linking, then the resistance to physical damage is improved, but the flexibility and adaptability of the sensor device may be reduced
Solution Approach 1:
The patent applies local quality by selectively cross-linking only the cover part of the sensor device while leaving other components unaffected. This localized modification provides enhanced hardness and physical damage resistance precisely where protection is needed (the outer cover), while the internal sensor elements and other components retain their original properties and flexibility, thus maintaining overall device adaptability.
