Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional wireless power supply methods are used, then wireless power reception is achieved, but power-receiving efficiency decreases
Solution Approach 1:
The patent transitions from conventional isotropic antenna radiation patterns to highly directional beamformed electromagnetic waves. By using multiple antennas arranged in specific geometries (planar, cylindrical, or spherical arrays) and applying phase control, the system concentrates energy transmission in the direction of the target device, significantly improving power-receiving efficiency while maintaining reliable power supply.
Solution Approach 2:
The patent combines multiple antenna elements into integrated antenna arrays with unified control. By merging multiple transmission antennas and coordinating their phases and amplitudes, the system achieves beamforming that concentrates electromagnetic energy, thereby improving power transfer efficiency compared to single-antenna conventional methods.
2Ease of operation
If antennas are provided in sensors and actuators for wireless power supply, then wireless power reception is enabled, but device size increases
Solution Approach 1:
The patent integrates antenna arrays within the existing device housing structure, nesting the power-receiving components inside the device's internal space. The antennas are arranged in compact configurations (such as planar arrays on circuit boards or cylindrical arrangements around the device body) that utilize the device's own volume efficiently, enabling wireless power reception without significant size increase.
Solution Approach 2:
The device housing serves multiple functions: it provides mechanical protection, structural support, and acts as the integration platform for antenna arrays. The housing design is optimized to accommodate wireless power reception components while maintaining the device's primary sensing or actuating functions, achieving multi-functionality without increasing overall device volume.
3Loss of energy
If multiple antennas are provided for wireless power supply, then power-receiving efficiency improves, but device complexity increases
Solution Approach 1:
The patent divides the antenna system into modular segments that can be independently designed and controlled. Each antenna element or sub-array can be optimized separately, and the overall system achieves high efficiency through coordinated operation of these segmented components. This segmentation simplifies the design and control of complex multi-antenna systems.
Solution Approach 2:
The patent introduces a control unit as an intermediary that manages the complex interactions between multiple antennas. This control unit coordinates phase and amplitude of each antenna element, enabling beamforming and directional energy transmission. By centralizing control functions, the system manages complexity while achieving high power-receiving efficiency.

AI summary
A device housing is provided for wirelessly receiving electric power in order to supply electric power to a device with an excellent power-receiving efficiency, while suppressing an increase in its size as a whole. Also, a device having the same device housing and a device housing for constituting a main body of a device which is a sensor or an actuator are provided. The device housing is provided with a power-receiving device for mainly generating an electric field or a magnetic field for performing wireless power supply. The power-receiving device includes at least one of a dipole antenna, a slot antenna, a monopole antenna, a chip antenna and an inverted-F antenna. The device housing has a size in a three-dimensional space, and expansion of its size in the three-dimensional space due to the provision of the power-receiving devices is substantially limited to one axis direction (X-axis direction) at most.
