Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measured value transmission arrangements are inflexible regarding the number of data bits to be transmitted, requiring multiple types of masters and slaves for different data bit counts, leading to increased development, production, and storage costs without expanding customer options.
Innovation Solution
The method adapts the number of data bits to be transmitted by either the slave or the master within a clock burst, allowing for dynamic adjustment based on clock cycles, reducing the variety of devices needed and enabling flexible data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of data bits to be transmitted is fixed in the slave and the number of clock cycles is fixed in the master, then the data transmission is reliable and synchronized, but the system lacks flexibility and requires multiple device types for different data bit counts
Solution Approach 1:
The patent applies dynamics by making the number of data bits transmittable dynamically adjustable in the slave device and the number of clock cycles adjustable in the master device. This allows the system to adapt to different transmission requirements without requiring multiple fixed-type devices, thereby improving versatility while reducing device variety complexity.
Solution Approach 2:
The patent changes the parameters of data bit count and clock cycle count from fixed values to adjustable variables. By enabling these parameters to be modified according to transmission needs, the system achieves greater flexibility without requiring different device types for different parameter settings.
2Adaptability or versatility
If multiple types of masters and slaves are produced for different data bit counts, then specific transmission requirements are met, but development, production, and storage costs increase
Solution Approach 1:
The patent implements universality by designing the slave device to handle multiple data bit counts and the master device to support multiple clock cycle counts through adjustable parameters. This multi-functional design allows a single device type to serve multiple transmission requirements, eliminating the need to produce multiple specialized device types and thereby reducing manufacturing costs and complexity.
3Manufacturing precision
If the number of clock cycles is precisely matched to the number of data bits, then transmission accuracy is ensured, but the system cannot adapt to variable transmission requirements
Solution Approach 1:
The patent applies dynamics by making both the data bit count in the slave and the clock cycle count in the master dynamically adjustable. This allows the precise matching between clock cycles and data bits to be maintained adaptively across different transmission scenarios, ensuring transmission accuracy while accommodating variable requirements.

AI summary
The method involves providing data bits (DB) of a measured value (MW) detected by a sensor (12). The measured value is provided for bit by bit serial transmission to a master (MA). The multiple transmitting data bits is determined and defined in a slave (SL) on the base of multiple clock cycles of a cycle bursts given by the master. An independent claim is also included for a device for serial data communication of a slave.
