LED Control Data Frames for Energy-Efficient Series Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods for LED control units are energy-intensive and prone to faults due to complex data stream interpretation and synchronization, especially in series connections, leading to inefficiencies and increased complexity, particularly in applications like electric vehicles where energy efficiency is critical.
Innovation Solution
A communication arrangement that generates data frames of minimum length, synchronizes communication using unambiguously coded control commands, and eliminates the need for empty frames, allowing for efficient and fault-proof data exchange between a command unit and LED control units connected in series, optimizing energy usage and reducing hardware requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If empty frames are transmitted to indicate no payload data, then communication synchronization is maintained, but energy consumption increases and fault susceptibility increases
Solution Approach 1:
The patent extracts and eliminates the empty frame transmission mechanism from the communication system. Instead of transmitting empty frames to indicate no payload data, the system uses a stop signal followed by immediate payload transmission, removing the unnecessary energy-consuming component while maintaining communication reliability through the stop signal's unambiguous positioning function.
Solution Approach 2:
The patent implements periodic stop signals at regular intervals to mark the end of data transmission. This periodic action provides clear synchronization markers without requiring continuous empty frame transmissions, thereby reducing energy consumption while maintaining reliable communication through the rhythmic signaling pattern.
2Measurement precision
If multiple circuits are installed for data stream interpretation and synchronization, then communication accuracy is improved, but device complexity increases and cost increases
Solution Approach 1:
The patent extracts and removes the complex data stream interpretation and synchronization circuits from the system. By using a simplified communication protocol with explicit stop signals and clear data delimitation, the patent eliminates the need for multiple interpretation circuits while maintaining communication accuracy through the unambiguous signaling structure.
Solution Approach 2:
The patent replaces complex electronic synchronization circuits with a protocol-based synchronization mechanism. Instead of using multiple hardware circuits to interpret and synchronize data streams, the system uses clearly defined stop signals and data delimitation markers that can be implemented through simpler hardware or even software-based timing mechanisms.
3Adaptability or versatility
If predefined data frames with fixed length are used, then compatibility across application scenarios is improved, but bit waste increases and fault susceptibility increases
Solution Approach 1:
The patent implements dynamic data frame length adjustment based on the actual payload size. Instead of using fixed-length predefined frames, the system transmits only the necessary number of bits for the actual data, with variable frame lengths adapted to the specific communication requirements. This dynamic approach eliminates bit waste while maintaining protocol compatibility through the standardized stop signal and data delimitation mechanisms.
