Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a camera device is provided outside the automobile with wireless image transmission, then the ease of operation is improved, but the reliability of power supply deteriorates
Solution Approach 1:
A magnetic attraction box serves as an intermediary component that provides both magnetic attraction for mounting and electrical power transmission. The box includes a power supply socket that electrically connects to the camera device through the magnetic connection, acting as a mediator between the power source and the camera.
Solution Approach 2:
The magnetic attraction box combines three functions into one component: (1) magnetic attraction for securing the camera device, (2) electrical power supply connection, and (3) structural mounting support. This merging eliminates the need for separate power cables and mounting brackets.
2Ease of manufacture
If a magnet is used to fix the camera device outside the automobile, then the ease of manufacture is improved, but the strength of fixation deteriorates
Solution Approach 1:
The magnetic attraction box merges magnetic attraction with mechanical structure. The box itself provides structural support and mounting surfaces, while the magnet provides additional retention force. This combination achieves both ease of manufacture and strong fixation.
Solution Approach 2:
The fixing system uses a composite approach combining magnetic fields (invisible force) with physical structural elements (the box and mounting bracket). This composite system leverages both electromagnetic attraction and mechanical strength for reliable fixation.
3Ease of operation
If a power supply socket is provided outside the tail portion of the automobile, then the ease of operation is improved, but the object-affected harmful factors worsen
Solution Approach 1:
The power supply socket is nested within the magnetic attraction box, which itself is mounted on the vehicle. This nesting protects the electrical connection from environmental factors while maintaining ease of connection. The box acts as a protective enclosure for the socket.
Solution Approach 2:
The magnetic attraction box serves as an intermediary that shields the electrical connection from direct exposure to environmental harmful factors. The box's structure protects the socket from water, dust, and physical damage while allowing easy access for connection.
4Device complexity
If wireless transmission is used for image signals, then the device complexity is reduced, but the loss of information worsens
Solution Approach 1:
The patent replaces mechanical/wired signal transmission with wireless transmission. This substitution eliminates physical cables while maintaining signal integrity through electromagnetic wave transmission, reducing complexity without significant information loss.
