Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If spatial transmission of feed light is performed without a surrounding member, then the transmission path remains open and accessible, but external objects are inevitably irradiated with feed light causing potential damage
Solution Approach 1:
A surrounding member (vacuum chamber) is introduced as an intermediary between the feed light and external objects. This chamber contains the feed light transmission path and prevents direct interaction between the high-power light and external objects, thereby eliminating the harmful irradiation effect while maintaining system functionality.
Solution Approach 2:
Air is extracted from the transmission path by creating a vacuum environment within the surrounding member. This removes the medium that would otherwise allow feed light to escape and irradiate external objects, while also preventing oxidation and other chemical reactions that could damage components.
2Reliability
If a surrounding member is introduced to enclose the transmission path, then external irradiation is prevented, but the system structure becomes more complex
Solution Approach 1:
The surrounding member serves multiple functions simultaneously: it encloses the transmission path to prevent feed light irradiation, maintains the vacuum environment to reduce light scattering and absorption, and provides structural support for the optical components. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The functions of light containment, vacuum maintenance, and structural support are merged into a single surrounding member structure. This integration simplifies the overall system design compared to having separate components for each function, thereby reducing complexity while maintaining reliability.
3Loss of energy
If air is present in the transmission path, then the system is easier to operate, but feed light experiences scattering and absorption losses
Solution Approach 1:
The physical parameter of the transmission medium is changed from atmospheric pressure to vacuum. This parameter change eliminates air molecules that cause scattering and absorption of feed light, thereby reducing energy loss. The vacuum state is maintained using a vacuum pump system.
Solution Approach 2:
A vacuum gauge is installed to monitor the vacuum level within the surrounding member and provide feedback to the control system. This feedback mechanism allows the vacuum pump to maintain the optimal vacuum pressure, ensuring minimal light loss while automatically adjusting to maintain ease of operation.

AI summary
To suppress an influence of radiation of feed light subjected to spatial transmission, in an optical power feeding system 1B for power feeding from PSE 110B to a PD 310 by spatial transmission of feed light 112, the PSE 110B includes a light emitter 111 configured to output the feed light 112, the PD 310 includes a light receiver 311 configured to convert the feed light 112 that has been received into electric power, and the optical power feeding system 1B includes a surrounding member 150B surrounding a transmission path of the feed light 112 from the light emitter 111 to the light receiver 311. When the surrounding member 150B is a tubular body inside which the transmission path of the feed light 112 passes, a cleaning device 161 configured to clean gas in the surrounding member 150B or a pressure reducing device 171 configured to reduce a pressure in the surrounding member 150B may be provided.
