Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If additional wireless base stations are installed in an area with existing base stations, then the coverage area and capacity are improved, but the complexity of optimizing installation positions increases due to interference and coverage overlap constraints
Solution Approach 1:
The patent segments the optimization process into three distinct steps: (1) determining terminal stations inside existing base station cover areas and excluding them, (2) optimizing combinations of terminal stations and closest additional base stations for terminals outside cover areas, and (3) determining whether terminal stations are inside or outside cover areas of additional base stations and modifying positions accordingly. This segmentation reduces the overall complexity by breaking down the complex optimization problem into manageable sequential tasks.
Solution Approach 2:
The patent applies preliminary action by first excluding terminal stations that are already inside existing base station cover areas before proceeding with optimization for additional base stations. This preliminary filtering step simplifies subsequent optimization by reducing the search space and avoiding redundant calculations for areas already covered.
2Quantity of substance
If the number of wireless base stations is increased to accommodate more users, then the network capacity is improved, but the cost of devices, installation, and operation increases
Solution Approach 1:
The patent applies local quality by determining installation positions of additional base stations based on local user distribution characteristics. The optimization process identifies specific areas where base stations are needed by analyzing which terminal stations are outside existing cover areas, and positions additional base stations locally in those specific regions rather than uniformly distributing them, thereby optimizing cost-effectiveness.
3Reliability
If wireless base stations are positioned closer to terminal stations to improve signal quality, then the communication quality is improved, but the risk of radio wave interference between base stations increases
Solution Approach 1:
The patent employs feedback mechanisms by iteratively determining cover areas of additional base stations based on their optimized positions, checking whether terminal stations are inside or outside these cover areas, and modifying positions of additional base stations that have terminal stations outside their cover areas. This feedback loop ensures that base stations are positioned to maximize coverage while maintaining appropriate spacing to avoid excessive interference.

AI summary
A method includes a step 1 of performing processing for determining wireless terminal stations that are inside cover areas of existing wireless base stations, and excluding the existing wireless base stations and the wireless terminal stations inside the cover areas from a wireless base station installation area, a step 2 of performing processing for optimizing, with respect to each first wireless terminal station that is outside the cover areas of the existing wireless base stations and has been left in the processing for excluding in the step 1, a combination of the first wireless terminal station and the closest additional wireless base station from which received power is the largest, and optimizing installation positions of additional wireless base stations, a step 3 of determining, with respect to the combinations of the additional wireless base stations and the first wireless terminal stations that were optimized in the step 2, whether wireless terminal stations are inside or outside cover areas of the additional wireless base stations, and performing processing for modifying an installation position of an additional wireless base station that accommodates a second wireless terminal station that is outside the cover area to increase the number of wireless terminal stations included in the cover areas.
