Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal mobility vehicles require a lamp fixture with a simpler structure due to limited mounting positions, necessitating a reduction in the number of components and complexity compared to traditional vehicle lamps.
Innovation Solution
A transportation device lamp fixture design that integrates a semiconductor light-emitting device, circuit board, and reflector directly onto the inside surface of the front cover or lamp body, eliminating the need for a separate support member, thus simplifying the structure and reducing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate support member is provided for the circuit board, then the circuit board can be securely mounted, but the lamp fixture structure becomes more complex and requires more parts
Solution Approach 1:
The circuit board is directly attached to the lamp body or front cover, merging the support function into existing structural components. This eliminates the need for a separate support member while maintaining secure mounting, thereby reducing device complexity and part count.
2Reliability
If more components are used to support the circuit board, then the mounting is more secure, but the lamp fixture becomes heavier and larger
Solution Approach 1:
By integrating the circuit board attachment directly into the lamp body or front cover structure, the support function is combined with existing structural elements. This eliminates additional components that would increase weight, maintaining secure mounting while minimizing lamp fixture weight.
3Reliability
If more components are used to support the circuit board, then the mounting is more secure, but the lamp fixture requires more assembly steps
Solution Approach 1:
The circuit board is directly attached to the lamp body or front cover, merging the support function into the main structural components. This integration reduces the number of separate assembly steps required, as there is no need to install a separate support member before mounting the circuit board, thereby improving productivity.
