Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging is used to charge the battery module, then charging function is provided, but the charging port is exposed to foreign substances and moisture
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless power transmission system. The wireless charging device transmits power through electromagnetic fields to the battery module without physical contact, eliminating the charging port opening and closing mechanisms while maintaining charging functionality.
Solution Approach 2:
The patent introduces a wireless power transmission intermediary system consisting of a charging device with transmitting antenna and a headset with receiving antenna. This intermediary wireless power transmission mechanism enables charging without direct physical connection, protecting the charging interface from environmental exposure.
2Ease of manufacture
If a charging port is provided in the headset, then wired charging is enabled, but the overall exterior design is compromised
Solution Approach 1:
The patent extracts and removes the charging port structure from the headset design. By eliminating the physical charging port opening, the design achieves cleaner exterior lines and better waterproofing without the complexity of port covers, seals, and switching mechanisms.
3Duration of action of moving object
If the battery module capacity is limited, then the headset size is controlled, but frequent charging is required
Solution Approach 1:
The patent implements preliminary charging action by enabling the battery module to be charged while still attached to the headset during normal use. The wireless charging device can charge the battery module proactively before complete discharge occurs, reducing the frequency of dedicated charging sessions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
