Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting device is integrated into a handheld electrosurgical instrument, then illumination precision is improved, but the device becomes bulky and difficult to manipulate
Solution Approach 1:
The lighting device is nested within the hollow cylindrical body of the electrosurgical instrument. The light source, battery, and control components are contained within the instrument's existing structure, allowing the lighting function to be integrated without significantly increasing the external dimensions of the handheld device.
Solution Approach 2:
The lighting device utilizes the longitudinal axis of the instrument by positioning the light source at the distal end, directing illumination along the length of the instrument toward the surgical site. This dimensional arrangement allows precise illumination without adding lateral bulk to the device.
2Duration of action of stationary object
If corded lighting devices are used, then continuous power supply is improved, but the device becomes cumbersome and requires constant repositioning
Solution Approach 1:
The power cord is extracted from the system by implementing a battery-powered design. The battery is housed within the instrument body, eliminating the need for external power connections and allowing the surgeon to manipulate the instrument freely without cord restrictions or constant repositioning requirements.
3Illumination intensity
If light sources are positioned close to the surgical site, then illumination effectiveness is improved, but the hands/tools block light and cast shadows
Solution Approach 1:
The lighting device employs multiple LED light sources arranged circumferentially around the distal end of the instrument. This distributed arrangement provides illumination from multiple angles and directions, reducing shadow casting by the instrument itself and ensuring comprehensive lighting of the surgical site from various local positions.
4Illumination intensity
If traditional lighting devices are used, then illumination is provided, but safety hazards occur due to heat and burns
Solution Approach 1:
The lighting device uses LED light sources that are solid-state, low-power consuming components with long operational lifetimes. LEDs generate minimal heat compared to traditional incandescent bulbs, eliminating burn hazards while providing sufficient illumination. The battery-powered design also eliminates the risk of electrical shocks from corded connections.
