Flexible Lamp Chain Potting Method for Even PCB Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing flexible lamp chains face challenges in ensuring even arrangement of the printed circuit board and achieving good waterproof performance while maintaining a aesthetically pleasing appearance.
Innovation Solution
A potting method involving a mold with a potting groove and a flexible fixing support that securely holds the printed circuit board in place, ensuring even arrangement and integration with the potting material for enhanced waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If potting material is directly potted in flexible PCB board, then process is simple and cost is low, but PCB board strips off easily and waterproof property is poor
Solution Approach 1:
The patent divides the potting structure into segments: a receiving groove is created in the potting material, separating the PCB mounting area from the potting material bulk. This segmentation allows the PCB to be securely held in the groove while the potting material provides waterproof protection around it, resolving the contradiction between simple process and good waterproofing.
Solution Approach 2:
The receiving groove acts as an intermediary structure between the PCB board and the potting material. It provides a dedicated space that holds the PCB in place while allowing the potting material to surround and protect it, thereby improving waterproof property without complicating the manufacturing process.
2Reliability
If PCB board is placed in receiving groove of potting material, then cost is low and waterproof property is good, but PCB board cannot be arranged evenly and appearance is poor
Solution Approach 1:
The patent applies local quality by designing the receiving groove with specific local features (dimensions, shape, position) that are optimized for holding the PCB board evenly. The groove's local characteristics ensure the PCB is properly positioned and arranged, improving appearance while maintaining the waterproof benefits of the potting structure.
3Reliability
If PCB board is directly packaged using potting material, then waterproof effect is fine, but PCB board cannot be arranged evenly in flexible lamp chain
Solution Approach 1:
The patent segments the packaging structure by creating a receiving groove within the potting material. This segmentation allows the PCB to be positioned and arranged evenly within the groove while the surrounding potting material provides the waterproof protection, simultaneously achieving both goals.
Solution Approach 2:
The receiving groove serves as an intermediary structure that facilitates even PCB arrangement while maintaining waterproof integrity. It provides a controlled environment for PCB placement within the otherwise solid potting material, resolving the contradiction between waterproofing and arrangement quality.
