Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple antennas are used in the control device to improve position determination accuracy, then the accuracy of specifying positions of battery state detection devices is improved, but the device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary approach by using the battery state detection devices themselves as reference points for position determination. Instead of adding multiple antennas to the control device, the system uses wireless communication strengths between the control device and multiple battery state detection devices, along with communication strengths among the battery state detection devices, to calculate positions. This intermediary use of existing devices as reference points resolves the contradiction by achieving accurate position determination without increasing the control device's antenna count.
Solution Approach 2:
The patent employs a virtual copying approach by creating a wireless communication strength map that replicates the spatial relationships between devices. Rather than physically duplicating antennas, the system copies the communication characteristics and uses them to construct position information. The processing unit calculates positions by analyzing patterns of wireless communication strengths, effectively creating a virtual model of the spatial arrangement without physical duplication of hardware.
2Measurement precision
If multiple antennas are used in the control device to improve position determination accuracy, then the accuracy of specifying positions of battery state detection devices is improved, but the cost increases
Solution Approach 1:
The patent uses battery state detection devices as intermediary reference points to determine positions without requiring expensive multiple antennas in the control device. By leveraging the wireless communication infrastructure already present in the battery state detection devices, the system achieves accurate position determination while avoiding the additional hardware costs that would result from installing multiple antennas in the control device.
Solution Approach 2:
The battery state detection devices serve themselves as reference points for position determination. Each device participates in the positioning process by providing its own wireless communication strength data to the control device, eliminating the need for the control device to invest in additional expensive antenna hardware. The system uses the existing capabilities of the battery state detection devices to perform the positioning function that would otherwise require costly additional equipment.
3Measurement precision
If wireless communication strengths among battery state detection devices are used to determine positions, then the accuracy of position determination is improved, but the loss of information increases due to similar reception strengths
Solution Approach 1:
The patent transitions from a one-dimensional measurement (single wireless communication strength between control device and each battery state detection device) to a multi-dimensional measurement system. By incorporating wireless communication strengths among multiple battery state detection devices in addition to those with the control device, the system creates a richer data matrix with multiple dimensions of information. This dimensional expansion allows the processing unit to differentiate between devices with similar reception strengths by analyzing the complete pattern of communication strengths across the network.
Solution Approach 2:
The system implements feedback by having battery state detection devices transmit their identification information and by the processing unit analyzing the complete set of wireless communication strengths to determine positions. The feedback loop allows the system to iteratively refine position calculations by considering all communication strength measurements, ensuring that even devices with similar reception strengths to the control device can be accurately differentiated through their unique communication patterns with other devices in the network.
