Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact terminals are protruded to the outside for charging connection, then electrical connection is achieved, but appearance becomes unattractive and contact state easily deteriorates due to external contamination
Solution Approach 1:
The patent extracts the contact terminals from the external environment by providing a protective cover that encloses them during non-charging periods. The cover can be opened or detached when charging is needed, allowing electrical connection while protecting the terminals from dust, moisture, and other contaminants when not in use.
Solution Approach 2:
The protective cover acts as an intermediary element between the contact terminals and the external environment. It provides a physical barrier that prevents direct exposure of the terminals to harmful external factors while still allowing the charging function to be performed when the cover is opened or removed.
2Ease of operation
If contact terminals are exposed for charging connection, then electrical connection is achieved, but risk of short-circuiting and energy loss increases due to moisture exposure
Solution Approach 1:
The contact terminals are extracted from continuous exposure to the environment by implementing a cover mechanism. The terminals remain enclosed during normal operation and are only exposed when charging is actively needed, thereby minimizing the window of opportunity for moisture contamination and short-circuiting.
Solution Approach 2:
The protective cover provides beforehand protection against moisture and contaminants that could cause short-circuiting. By maintaining the terminals in a protected state during non-charging periods, the system preemptively prevents potential harmful effects before they can occur.
3Adaptability or versatility
If wireless charging components are integrated into the device body, then charging function is achieved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The wireless charging system is segmented into separate functional modules: a power receiving device with coil and charging circuit, and a detachable protective cover. This modular segmentation allows each component to be manufactured and tested independently, then assembled into the final product, thereby reducing overall manufacturing complexity.
Solution Approach 2:
The power receiving device is designed as a universal module that can be applied to various portable electronic devices. By standardizing this component, manufacturers can reuse the same design across different product lines, reducing the need for custom manufacturing processes and lowering overall complexity.
