Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional molding operations are used to enclose electro-magnetic components, then water resistance is achieved, but assembly complexity and manufacturing time increase
Solution Approach 1:
The capture device is divided into a base module and a cap module that can be assembled separately and then connected to enclose the electro-magnetic component. This segmentation allows for simpler individual components that are easier to manufacture and assemble, while still providing effective water resistance when connected together.
Solution Approach 2:
A sealing agent is introduced as an intermediary substance between the base module and cap module to create a water-resistant seal. This sealing agent fills gaps and crevices at the interface between modules, providing reliable water protection without requiring complex molded enclosures.
2Productivity
If modular capture devices are used for easy assembly, then manufacturing time is reduced, but water-resistant sealing reliability may compromise
Solution Approach 1:
The sealing agent is applied in advance to the mating surfaces of the base module and cap module before assembly. This preliminary application ensures that when the modules are connected, the seal is already in place, maintaining water resistance reliability while enabling quick modular assembly.
Solution Approach 2:
The sealing agent undergoes a parameter change from liquid to solid state after application, transforming from a flowable substance that can be easily applied during assembly to a rigid seal that provides reliable water protection once cured.
3Reliability
If deformable base modules are used to provide compressive seals, then water resistance is improved, but structural stability may be reduced
Solution Approach 1:
The base module is designed with deformable characteristics that allow it to dynamically adjust its shape during assembly to create compressive seals against the cap module. This dynamic deformation capability enables reliable water sealing while the overall modular structure maintains sufficient structural stability for the application.

Function Achieved in This Case
Enables rapid assembly of light strings with improved yield and reduced costs, allowing for field replacement of components and effective water resistance through dual interface seals that prevent water penetration.
Implementation Method 1
When the base module and cap module are connected, the base module deforms to provide a compressive seal to an interior of the capture device
Implementation Method 2
the base module may be deformable and deform when affixed to the cap module

AI summary
A water-resistant enclosure having a base module, a cap module connected to the base module to define a cavity configured to receive a light emitting device, and apertures formed in at least one of the base module and cap module for wires to pass through. The base module may be deformed when affixed to the cap module, or a sealing agent may be disposed in the cavity, such that the cavity is waterproof.
