Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cards are inserted into the card slot, then the doll can play audio and control eye movements, but the doll may not reliably trigger the correct key if card insertion direction varies
Solution Approach 1:
The patent applies asymmetry by making the push button bulges asymmetrically positioned on the card, corresponding to specific keys on the input keyboard. This asymmetric design ensures that only the correct key is triggered when the card is inserted in the proper direction, while preventing incorrect triggering when inserted in wrong directions, thus resolving the contradiction between insertion flexibility and key triggering reliability.
2Adaptability or versatility
If simple functions are used in dolls, then the device complexity is low, but the interaction and learning functions are insufficient
Solution Approach 1:
The patent applies multi-functionality by integrating multiple functions into a single system: the input keyboard enables remote control, the card slot provides learning functionality through educational cards, the speaker delivers audio output, and the eye movement mechanism creates interactive engagement. This combination of multiple functions in one device resolves the contradiction between enhanced interaction/learning capabilities and device complexity.
Solution Approach 2:
The patent uses an infrared signal as an intermediary between the remote control and the doll's control circuit. The infrared transmission module receives infrared signals from the remote control and converts them into control commands, enabling complex interactions without requiring direct electrical connections or complex wiring between components.
3Reliability
If positioning mechanisms are added to ensure correct card insertion, then key triggering reliability improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the positioning function into two separate components: positioning grooves formed on the card slot and positioning protrusions formed on the card. This segmentation allows each component to be independently designed and manufactured, simplifying the overall positioning mechanism while ensuring reliable directional control for card insertion.
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
Enhances user interaction and provides a learning function by ensuring consistent key triggering regardless of card insertion direction, enabling the doll to play audio and control eye movements based on card content.
Implementation Method 1
the first processor is used for controlling the infrared emission circuit to emit an infrared signal according to an input of the input keyboard
Implementation Method 2
the infrared receiver receives the infrared signal emitted by the infrared emission circuit and transfers the infrared signal to the second processor
