Solution Overview
Problem
Existing techniques for manufacturing chassis components for electronic devices are limited in producing thin, low-cost components with high-quality finishes, particularly for devices like laptop computers and tablets.
Innovation Solution
The method involves forming a polymer layer with a first metallic layer on one side and a second metallic layer on the other, incorporating integrated structures such as antennas, power transmission cables, and sensors, achieved through electroplating and selective patterning with resist layers to create functional and cosmetic features.

Engineering Contradiction Analysis
1Length of moving object
If existing manufacturing techniques are used for chassis components, then production is simpler and cost is lower, but thickness cannot be reduced sufficiently and finish quality is limited
Solution Approach 1:
The patent employs a composite structure consisting of a polymer substrate layer combined with electroplated metallic layers. This composite material approach enables the chassis to achieve thin thickness (0.6mm to 1.2mm) while maintaining structural integrity and high-quality metallic finish, resolving the contradiction between reducing thickness and maintaining manufacturability
Solution Approach 2:
The patent replaces traditional mechanical fastening and assembly methods with electroplating technology. By depositing conductive metallic layers directly onto the polymer substrate, the chassis achieves both structural function and electrical functionality (antenna, RF shielding, EMI/EMC) without additional mechanical components, thereby reducing thickness while simplifying the manufacturing process
2Manufacturing precision
If traditional chassis manufacturing is used, then production cost is lower, but finish quality and functional integration are limited
Solution Approach 1:
The electroplated metallic layers serve multiple functions simultaneously: providing aesthetic metallic finish, enabling antenna functionality, offering RF shielding, and ensuring EMI/EMC compliance. This multi-functionality approach allows the chassis to achieve high manufacturing precision and quality finish while integrating multiple functions into a single component, reducing overall device complexity
Solution Approach 2:
The patent merges cosmetic finish and functional elements into a single integrated chassis component. By combining the polymer substrate with electroplated metallic layers that provide both aesthetic and functional properties, the design eliminates the need for separate cosmetic covers and functional components, thereby achieving high finish quality without increasing device complexity
3Length of moving object
If electroplated plastic chassis is used, then thinness and finish quality are improved, but manufacturing process becomes more complex
Solution Approach 1:
The patent applies preliminary electroplating treatment to the polymer substrate before final assembly. By pre-depositing the metallic layers with required thickness and pattern during the substrate fabrication stage, the process simplifies subsequent assembly operations and enables the final thin chassis dimensions to be achieved without adding complexity to later manufacturing steps
