Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two sets of signal contacts are arranged along a straight line to enable bidirectional connection, then the tablet computer can be connected in either direction, but the number of signal contacts increases occupying extra space
Solution Approach 1:
The patent merges the functions of multiple signal contacts into a single set of contacts. By using a single set of signal contacts arranged in parallel in the center, the system eliminates the need for two separate sets, thereby reducing the number of contacts while maintaining bidirectional connection capability through automatic signal detection and reordering
2Adaptability or versatility
If two sets of signal contacts are arranged in parallel in the center to enable bidirectional connection, then the tablet computer can be connected in either direction, but the thickness increases
Solution Approach 1:
The patent merges multiple contact sets into a single compact arrangement. By positioning one set of signal contacts in the center and using a decision circuit to handle bidirectional signal routing, the design achieves space efficiency and reduced thickness while maintaining the ability to connect in either direction
3Adaptability or versatility
If an extra set of signal contacts is added to support bidirectional connection, then connection flexibility is improved, but space occupation increases
Solution Approach 1:
The single set of signal contacts serves multiple functions by supporting bidirectional connections. The decision circuit enables the same physical contacts to correctly route signals regardless of connection orientation, making the contact system universal and multi-functional without requiring additional contacts

the decision circuit detects a current outputted from the first direct current power source flowing from the first contact towards the third contact
Data Source
AI summary
A first electronic device has a first side provided with first and second contacts. The first contact is connected to a direct current power source and the second contact is grounded. A second electronic device has a decision circuit and a second side removably connected to the first side. The second side includes third and fourth contacts. When the first and second electronic devices are connected in a first configuration, the decision circuit outputs a first signal according to the first configuration, whereas when the electronic devices are connected in a second configuration opposite to the first configuration, the decision circuit outputs a second signal according to the second configuration.
