Lens Holder Heating Strip With Flexible PCB Electrical Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for electrical connections in vehicle-mounted electronic components, such as heating elements, are bulky, expensive, and heavy, making them inefficient for withstanding environmental constraints like cold and ice.
Innovation Solution
A flexible printed circuit board is used as both the heating strip and electrical connection means, with a thinned portion for substrate continuity, allowing for a compact and adaptable electrical connection system that includes an elastic attachment mechanism to fit the lens support's profile, reducing bulk and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical harnesses and connectors are used for heating elements, then reliable electrical connection is achieved, but the device becomes bulky, heavy, and expensive
Solution Approach 1:
The patent combines the heating element and electrical connection functions into a single integrated flexible printed circuit board structure. The FPCB serves both as the heating element carrier and as the electrical connection medium, eliminating the need for separate electrical harnesses and connectors. This merging of functions directly reduces device weight while maintaining reliable electrical connection.
Solution Approach 2:
The flexible printed circuit board performs multiple functions simultaneously: it provides structural support for the heating element, serves as the electrical connection pathway, and acts as the heating element itself when conductive traces are formed on it. This multi-functionality eliminates the need for separate specialized components, reducing overall device weight and complexity.

3Stability of the object's composition
If rigid printed circuit board substrate is used for heating element connection, then structural stability is achieved, but adaptability to different profiles is reduced
Solution Approach 1:
The patent transitions from a rigid printed circuit board substrate to a flexible printed circuit board that can dynamically adapt its shape. The FPCB can bend and conform to different lens holder profiles while maintaining structural integrity and electrical connection reliability. This dynamic flexibility allows the same component to adapt to various geometric configurations.
Solution Approach 2:
The patent employs a flexible printed circuit board instead of a rigid substrate. The FPCB's flexible nature allows it to conform to the specific profile of the lens holder while maintaining electrical connection stability. This flexible film approach provides both the needed adaptability to different profiles and sufficient structural stability for reliable operation.
