LED Light String Transparent Shell Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED light strings have poor waterproof performance and a short lifespan due to direct exposure of pins and reliance on waterproof glue tape, which poses safety hazards and leakage risks.
Innovation Solution
The use of transparent light shells that encase each LED light bead and wire connecting position, with conductive structures penetrating through and sealed by injected transparent liquid glue, providing a better sealing effect and prolonged service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional LED light strings use two pins directly exposed and wrap or seal with waterproof glue tape, then the structure is simple and easy to manufacture, but the waterproof performance is poor and service life is short
Solution Approach 1:
The patent divides the light string into modular units, with each LED light bead enclosed in a separate transparent shell. This segmentation allows each unit to be independently sealed and protected, improving overall waterproof performance while maintaining manufacturing simplicity through standardized modules.
Solution Approach 2:
The patent implements a nested structure where the LED light bead is placed inside the transparent shell, and the wire connecting position is sealed within the same shell. This nested arrangement protects multiple components (bead, wire connection) simultaneously, enhancing waterproofing without proportionally increasing complexity.
2Duration of action of stationary object
If conventional LED light strings use exposed pins and waterproof glue tape sealing, then the manufacturing process is simple, but the service life is relatively short
Solution Approach 1:
The patent applies preliminary action by pre-sealing the wire connecting position and LED light bead within the transparent shell before final assembly. This pre-protection ensures that critical components are shielded from environmental factors early in the manufacturing process, extending service life while maintaining ease of manufacture through streamlined integration.
Solution Approach 2:
The transparent shell serves as an intermediary structure that mediates between the LED light bead/wire connection and the external environment. It provides a protective barrier that extends service life by isolating sensitive components from moisture and environmental factors, while its standardized design keeps manufacturing simple.
3Reliability
If conventional LED light strings use waterproof glue tape sealing, then the structure remains simple, but leakage risk and safety hazards increase
Solution Approach 1:
The patent employs transparent shells that function as flexible protective barriers, replacing rigid or adhesive-based sealing methods. These shells provide reliable leakage resistance by completely enclosing the LED light bead and wire connecting position, while their modular design prevents the complexity increase associated with multi-layer adhesive systems.
