Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical environments, the presence of multiple devices around a patient can lead to interference and collisions, hindering treatment due to inadequate positioning and lack of freedom of movement, especially in emergency situations.
Innovation Solution
A system utilizing cameras for spatial recording, an electronic control unit for checking and optimizing device placement, and video projectors for feedback, ensuring unobstructed movement and collision-free positioning through real-time warnings and projections of optimal device positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are positioned around the patient for treatment, then the treatment functionality is improved, but the freedom of movement and risk of collisions worsen
Solution Approach 1:
The system performs preliminary positioning and checking of devices before treatment begins. The control unit checks whether devices are positioned in a collision-free manner and whether freedom of movement is sufficient before the treatment starts, allowing preventive adjustment rather than reactive problem-solving during the procedure.
Solution Approach 2:
The system continuously monitors device positions and provides feedback signals when collisions or insufficient freedom of movement are detected. The control unit receives signals from sensors detecting device positions and outputs warning signals or corrective recommendations to maintain optimal spatial arrangement throughout the treatment.
2Ease of operation
If devices are positioned on the floor surface for easy access, then the ease of operation is improved, but the reliability and safety worsen due to potential collisions and interference
Solution Approach 1:
The system applies preliminary anti-action by detecting potential collisions and interference risks before they occur. The control unit checks device positions in advance and issues warning signals or corrective recommendations to prevent collisions and interference, thereby maintaining safety while allowing devices to be positioned for easy access.
3Stability of the object's composition
If devices are fixed in pre-positioned locations, then the stability of spatial distribution is improved, but the adaptability for emergency situations worsens
Solution Approach 1:
The system transitions from static pre-positioning to dynamic monitoring and adjustment. While devices have predetermined positions for stability, the control unit continuously monitors their positions and can detect when emergency devices need to be introduced, allowing the spatial distribution to adapt dynamically to changing treatment requirements.
4Measurement precision
If comprehensive monitoring of device positions is implemented, then the measurement precision is improved, but the device complexity worsens
Solution Approach 1:
The control unit acts as an intermediary that simplifies the overall system architecture. It receives signals from multiple sensors detecting device positions, processes this information centrally, and generates appropriate output signals or recommendations, thereby coordinating the complex monitoring function through a single managing component.

AI summary
In order, despite a plurality of terminals, to enable their freedom of movement on the one hand and an unimpeded treatment process on the other hand to be guaranteed, there is provision in accordance with the invention, for recording the devices in their envisaged spatial distribution, especially by at least one camera, to check this distribution as regards a sufficient freedom of movement of the devices, especially by a processing or control unit, and to feed back a corrected distribution, especially by at least one video projector.
