Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If only a portion of the entire electrode is in contact with the skin and energy is irradiated, then energy transmission efficiency is improved, but burn accidents occur due to concentrated energy on a narrow area
Solution Approach 1:
The patent implements a feedback mechanism by detecting the contact state between the electrode and skin, then adjusting the energy transmission accordingly. The system monitors contact area and uses this information to control energy delivery, preventing burn accidents while maintaining efficient energy transmission when proper contact is established.
Solution Approach 2:
The patent applies dynamics by making the energy transmission system adaptive and variable rather than fixed. The energy delivery is dynamically adjusted based on real-time detection of contact state, allowing the system to optimize performance while preventing harmful effects under varying operating conditions.
2Ease of operation
If conventional skin care devices irradiate energy without accurate contact determination, then device operation is simple, but optimal energy transmission cannot be achieved and burn accidents cannot be prevented
Solution Approach 1:
The patent implements self-service by enabling the device to automatically detect its own contact state with the skin and autonomously adjust energy transmission parameters. The system performs self-diagnosis and self-regulation without requiring user intervention, maintaining ease of operation while significantly improving reliability and burn prevention capability.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor contact conditions and automatically adjust energy delivery parameters. This closed-loop control enables the device to maintain safe and effective operation without requiring complex user input or manual adjustments.
3Reliability
If sensor assemblies and processing units are added to detect contact and pressing states, then burn prevention capability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing sensor assemblies and processing units that serve multiple functions simultaneously. The detection system not only monitors contact state for burn prevention but also optimizes energy transmission efficiency and provides operational feedback, reducing the need for separate dedicated components for each function.
Solution Approach 2:
The patent merges the detection, processing, and control functions into an integrated system. The sensor assemblies are combined with the processing unit to form a unified contact state determination system, reducing overall device complexity while maintaining comprehensive burn prevention capability.
