Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lithium-ion batteries are used in handheld surgical devices, then power capacity is improved, but sterilization cost increases due to requiring expensive hydrogen-peroxide sterilization
Solution Approach 1:
The power supply system is divided into two separate components: a handheld surgical device with a battery that can withstand sterilization, and a separate external DC power supply that does not require sterilization. This segmentation allows each component to be optimized independently for its specific requirements.
Solution Approach 2:
The high-cost sterilization requirement is extracted from the power supply system by separating the battery component that needs sterilization from the external DC power supply that does not. The external power supply can be sterilization-resistant, eliminating the need for expensive hydrogen-peroxide sterilization processes.
2Use of energy by moving object
If lithium-ion batteries are used in handheld surgical devices, then power capacity is improved, but device availability decreases due to sterilization limitations
Solution Approach 1:
The power supply system is segmented into a handheld device with a sterilization-resistant battery and an external DC power supply. This allows the handheld device to maintain availability through standard sterilization methods while the external supply provides additional power capacity without sterilization constraints.
Solution Approach 2:
The sterilization limitation is extracted from the power supply system by separating the battery component from the external DC power supply. The external power supply can be made available without undergoing expensive and time-consuming hydrogen-peroxide sterilization, thereby improving overall device availability.
3Weight of moving object
If internal battery is used in handheld surgical device, then portability is improved, but power capacity during peak usage is insufficient
Solution Approach 1:
The power supply system merges the handheld device with a battery for portability with an external DC power supply for additional power capacity. The external power supply is connected via a cable, allowing the system to combine the advantages of both portable and high-power configurations during procedures.
Solution Approach 2:
The power supply configuration is made dynamic, allowing the handheld device to operate independently with its battery for portable operations, or to connect with the external DC power supply when additional power capacity is needed during peak usage periods.
4Power
If external DC power supply is added to handheld surgical device, then power capacity is improved, but device complexity increases
Solution Approach 1:
The power supply system is segmented into a handheld surgical device and a separate external DC power supply connected by a cable. This segmentation minimizes the complexity increase in the handheld device itself, as the external supply handles the additional power requirements without requiring complex internal modifications.
Solution Approach 2:
The additional power capacity is extracted from the handheld device by using a separate external DC power supply. This approach adds power capacity without requiring complex internal modifications to the handheld device, thereby minimizing the increase in device complexity.
