Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid TDMA data transmission block is defined for different communication systems with different numbers of nodes, then the system structure is simple and easy to implement, but the frame length cannot be adapted to changes in the number of nodes, leading to communication delays and reduced efficiency
Solution Approach 1:
The patent implements dynamic frame configuration where the TDMA data transmission block structure automatically adapts to the current number of nodes. The frame length is no longer fixed but dynamically adjusted based on the actual number of active nodes in the communication system, allowing the system to optimize its performance for varying node counts without manual reconfiguration.
Solution Approach 2:
The invention changes the frame length parameter dynamically according to the number of nodes. By making the frame length a variable parameter rather than a constant, the system can optimize communication efficiency for different network sizes. The base station determines the current number of nodes and configures the appropriate frame length accordingly, transforming a static parameter into a dynamic one that responds to system conditions.
2Productivity
If the frame length is fixed for a TDMA communication system, then the system configuration is simple, but adding or removing nodes requires manual reconfiguration and causes communication delays
Solution Approach 1:
The patent implements a feedback mechanism where the base station continuously monitors the number of active nodes in the communication system. Based on this feedback information, the base station automatically adjusts the frame length of the TDMA data transmission block to match the current system state, ensuring optimal communication efficiency without manual intervention and minimizing delays during node additions or removals.
Solution Approach 2:
The system performs self-configuration through automatic frame length adaptation. When nodes are added or removed, the base station autonomously determines the new number of nodes and reconfigures the TDMA frame structure without requiring manual user intervention. This self-service capability eliminates communication delays associated with manual reconfiguration and maintains continuous optimal performance.
3Adaptability or versatility
If manual reconfiguration is required when adding or removing nodes, then the system maintains precise control over frame structure, but user intervention is required and system adaptability is reduced
Solution Approach 1:
The patent enables the TDMA communication system to automatically adapt to changes in node count through self-service configuration. The base station autonomously monitors node additions or removals and adjusts the frame length of data transmission blocks without requiring user intervention. This maintains precise control over frame structure while eliminating the need for manual reconfiguration, thereby improving both adaptability and ease of operation.
Solution Approach 2:
The system performs preliminary configuration actions by maintaining a pool of configurable frame structures that can be quickly activated based on the current number of nodes. When nodes are added or removed, the base station can immediately switch to an appropriate pre-prepared frame configuration, enabling rapid adaptation without manual intervention and maintaining system control.

AI summary
A method for configuring TDMA data transmission blocks in a TDMA communication system with multiple nodes (S.1...SN) and a base station (BS) is proposed, wherein the base station (BS) determines the number of nodes (S.1...SN) in a first step, wherein the base station (BS) forms TDMA data transmission blocks (FR.1...FR.m) in a second step, in which the number (N) of timeslots is equal to the determined number (N) of nodes, and wherein the base station (BS) informs each node (S.1...SN) which timeslot (TS.1...TS.N) is assigned to it within the formed TDMA data transmission blocks in a third step.
