Solution Overview
Problem
Conventional automobile tail light devices have complex assembly processes due to numerous component parts, making the assembly task inconvenient.
Innovation Solution
A tail light device with a simplified modular design, featuring a housing with a surrounding wall and a mounting fixture that accommodates integrally formed frames with mounting walls, allowing for easy assembly of light emitting modules, including first and second light emitting modules that emit light based on different operation modes, and a third module for light scattering, facilitating assembly and reducing assembly time and potential damage.

Engineering Contradiction Analysis
1Ease of operation
If conventional light emitting modules with multiple component parts are used, then the light emitting modules can provide complete lighting functions, but the assembly process becomes complex and inconvenient
Solution Approach 1:
The patent divides the tail light device into modular components: a housing assembly, a mounting fixture with integrally formed frame, and separate light emitting modules. Each module can be assembled and tested independently before final installation, significantly simplifying the overall assembly process and reducing the complexity of handling numerous small parts simultaneously.
Solution Approach 2:
The mounting fixture integrates multiple functions into a single component: it provides structural support, contains mounting walls for securing light emitting modules, and forms an integral frame that attaches to the housing. This merging of functions reduces the number of separate parts and simplifies assembly operations.
2Productivity
If multiple light emitting modules with numerous components are assembled sequentially, then complete lighting functionality is achieved, but assembly time increases and risk of component damage rises
Solution Approach 1:
The mounting fixture is prepared in advance with integrally formed frames and pre-positioned mounting walls. Light emitting modules can be pre-assembled on the mounting fixture before final housing assembly, allowing for preliminary testing and adjustment without risking damage to components during the final assembly process.
Solution Approach 2:
The housing and mounting fixture provide protective structures that cushion and protect light emitting modules during assembly and installation. The integrally formed frame and mounting walls secure modules in predetermined positions, preventing accidental damage from misalignment or improper handling.
