Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular lamp systems do not allow for the modification or addition of functions after a vehicle is purchased, requiring replacement of the lamp unit or the vehicle to implement new features.
Innovation Solution
A vehicular lamp system that includes a lamp unit, a vehicle storage unit, a communication unit, and a control unit, which enables the acquisition and execution of function information from an external storage unit or user terminal, allowing for the modification or addition of functions without replacing the vehicle or lamp unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific lamp is mounted in a vehicle to execute specific functions, then the lamp can perform predetermined functions, but the functions cannot be modified or added after vehicle purchase
Solution Approach 1:
The lamp system transitions from a static configuration to a dynamic one by enabling function information to be updated and modified after vehicle purchase. The control unit receives updated function information from external storage units, allowing the lamp's operational characteristics to change over time based on user needs or new requirements.
Solution Approach 2:
The lamp system is divided into separate functional components: the physical lamp unit, the control unit, and the function information stored in external storage units. This segmentation allows the function information to be independently updated without replacing the entire lamp system, thereby improving adaptability while maintaining system simplicity.
2Adaptability or versatility
If function information is stored in an external storage unit and acquired through communication, then functions can be modified post-purchase, but communication traffic increases
Solution Approach 1:
Instead of transmitting large amounts of data repeatedly, the system stores function information in external storage units and only communicates necessary identification or selection information. The control unit retrieves the actual function information from the external storage unit based on this minimal communication, significantly reducing communication traffic while maintaining full adaptability.
3Adaptability or versatility
If multiple operation programs are stored in the vehicle storage unit, then various lamp functions can be executed, but storage capacity requirements increase
Solution Approach 1:
The system extracts and moves the bulk of operation programs and function information from the vehicle's internal storage unit to external storage units. The vehicle storage unit retains only essential data such as identification information or minimal program references, dramatically reducing storage capacity requirements while preserving the ability to execute multiple lamp functions through external program retrieval.

AI summary
The present disclosure provides a vehicular lamp system in which modification or addition of functions of a lamp may be performed even after a vehicle is purchased. The vehicular lamp system includes a lamp unit; a vehicle storage unit configured to store first identification information; a communication unit configured to communicate with an external storage unit which stores second identification information corresponding to the first identification information, and function information associated with the second identification information and related to a user's selected function of the lamp unit; and a control unit configured to control an operation of the lamp unit. The communication unit acquires the function information associated with the second identification information corresponding to the first identification information from the external storage unit, and the control unit operates the lamp unit based on the function information to execute a specific function.
