Moisture-Resistant Coating for Assembled Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, especially portable ones, are vulnerable to water damage due to the lack of effective moisture protection within their internal components, which can void warranties and lead to costly repairs or replacements.
Innovation Solution
A method and system for applying protective coatings, such as moisture-resistant coatings, to the internal surfaces of fully assembled electronic devices, either through direct introduction into the device or by partially disassembling it to expose components, using techniques like chemical vapor deposition or physical vapor deposition, ensuring protection against water and other external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective coatings are applied to internal surfaces of fully assembled electronic devices, then moisture resistance is improved, but device complexity increases due to additional coating application steps and equipment
Solution Approach 1:
The patent applies protective coatings to internal surfaces before final assembly of the electronic device. This preliminary action allows the coatings to be applied to accessible surfaces while the device is in a semi-assembled state, avoiding the need for complex disassembly procedures later. The coating application occurs during the manufacturing process when components are still accessible, thereby improving moisture resistance without adding significant complexity to the final assembled product.
Solution Approach 2:
The patent employs a multi-layer coating system where different protective layers are applied sequentially to internal surfaces. Each layer serves a specific function (e.g., adhesion promotion, moisture barrier, corrosion protection), and the layers are nested together to provide comprehensive protection. This nested approach allows the device to achieve high moisture resistance through multiple specialized layers rather than a single complex coating process.
2Ease of manufacture
If protective coatings are applied to internal surfaces by disassembling the device, then coating accessibility is improved, but manufacturing time increases due to disassembly and reassembly operations
Solution Approach 1:
The patent applies protective coatings to internal surfaces during the assembly process before the device is fully enclosed. By performing the coating operation at this intermediate stage, components are naturally more accessible without requiring deliberate disassembly. This preliminary coating action eliminates the need for time-consuming disassembly-reassembly cycles while ensuring thorough coverage of internal surfaces that would otherwise be difficult to reach.
Solution Approach 2:
The patent divides the electronic device into modular sections or subassemblies that can be coated independently. By segmenting the device into manageable units with exposed internal surfaces, the coating process can be applied efficiently to each segment separately. This segmentation allows parallel processing of multiple components and eliminates the need to disassemble the entire device, thereby reducing overall manufacturing time while maintaining coating accessibility.
3Reliability
If protective coatings are applied to internal surfaces, then protection against water damage is improved, but production cost increases due to additional materials and processing steps
Solution Approach 1:
The patent employs protective coating materials that provide multiple functions simultaneously: moisture barrier, corrosion protection, and adhesion promotion. By using multi-functional coating formulations, the patent achieves comprehensive water damage protection without requiring separate specialized coatings for each protective function. This universality reduces the total number of coating layers needed, thereby lowering material costs and processing time while maintaining robust protection against water damage.
Solution Approach 2:
The patent optimizes coating application parameters such as thickness, composition, and curing conditions to achieve maximum protective performance at minimum material usage. By carefully controlling these parameters, the patent ensures that the protective coating provides adequate water damage protection with thin, material-efficient layers. This parameter optimization reduces material consumption and processing energy requirements, thereby lowering production costs while maintaining high levels of protection.

AI summary
Methods for applying protective coatings to electronic devices that have already been assembled, and are in a consumer-ready or aftermarket form, are disclosed. In such a method, an electronic device may be at least partially disassembled to expose at least a portion of an interior of the electronic device. A protective coating is applied to some or all of the exposed surfaces of the electronic devices, including one or more internal surfaces, features or components of the electronic device. Thereafter, the electronic device may be reassembled. During and after reassembly, the protective coating resides internally within the electronic device. Systems for applying protective coatings to interior components of previously assembled electronic devices are also disclosed.
