Solution Overview
Problem
Existing smart devices suffer from excessive and complex internal wiring due to separate functional modules requiring electrical connections through wires, leading to intricate structures and increased costs.
Innovation Solution
An integrated module comprising a printed circuit board with a body and a convex portion, where smaller first function modules are on the body and larger second function modules are on the convex portion, reducing the width of the board and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional modules are divided and installed separately according to location requirements, then each module can be positioned optimally, but internal wiring becomes excessive and complex
Solution Approach 1:
The patent combines multiple functional modules (first function module and second function module) onto a single printed circuit board, eliminating the need for separate wiring connections between independently installed modules. The PCB serves as a common platform that integrates both modules, thereby reducing internal wiring complexity while maintaining optimal positioning through PCB layout design.
2Device complexity
If multiple functional modules are integrated on a single printed circuit board, then internal wiring is simplified, but the board width increases causing abrupt conflict in device appearance
Solution Approach 1:
The patent extends the printed circuit board in the length direction rather than increasing width, creating a longitudinal layout where the first function module and second function module are arranged along the length of the PCB. This dimensional shift allows multiple modules to be integrated without increasing board width, avoiding abrupt conflict in device appearance while maintaining simplified wiring.
3Shape
If the printed circuit board width is reduced to avoid abrupt conflict, then device appearance is harmonious, but available space for functional modules is limited
Solution Approach 1:
The patent compensates for reduced board width by utilizing the length dimension more effectively. The PCB is designed with extended length to provide sufficient mounting space for both functional modules, while maintaining a narrow width profile that ensures harmonious device appearance. This longitudinal arrangement maximizes space utilization within the constrained width.
4Adaptability or versatility
If functional modules are connected through wires, then module placement flexibility is maintained, but manufacturing costs increase
Solution Approach 1:
The patent integrates multiple functional modules onto a single printed circuit board with standardized dimensions, which reduces manufacturing costs through economies of scale and simplified assembly processes. The PCB serves as a unified platform that eliminates the need for separate wiring harnesses and connection components, thereby reducing overall manufacturing complexity and cost while maintaining placement flexibility through PCB design variations.

AI summary
An integrated module includes a printed circuit board body and a printed circuit board convex portion. The printed circuit board convex portion is arranged on one side of a width extension direction of the printed circuit board body. A second function module with larger volume is arranged on the printed circuit board convex portion, and a first function module with smaller volume is arranged on the printed circuit board body, so that the width of the printed circuit board body may be made smaller, and the width of the printed circuit board body may be made less than 8.5±0.1 mm, thereby realizing the low profile effect during the assembly of the integrated module and avoiding the abrupt conflict of the entire intelligent device caused by the assembly of the integrated module due to the excessive width of the integrated module.
