Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital image data transmission is increased to handle higher pixel density, then image quality is improved, but transmission delay and electromagnetic interference increase
Solution Approach 1:
The patent replaces the electrical signal transmission system with an optical signal transmission system. The image sensor converts light signals into optical signals that are transmitted through optical fibers to the application processor, eliminating the need for electrical circuit board transmission. This substitution resolves the transmission delay and electromagnetic interference problems while maintaining high image quality from increased pixel density.
Solution Approach 2:
The patent introduces an optical fiber as an intermediary medium between the image sensor and application processor. The optical fiber serves as a mediator that transmits optical signals without the electromagnetic interference and signal noise that plague electrical transmission, thereby enabling rapid transmission of high-quality image data from high-density pixel sensors.
2Productivity
If circuit board density is increased to transmit more data, then data transmission capacity is improved, but electromagnetic wave interference and signal noise increase
Solution Approach 1:
The patent substitutes the electrical circuit board transmission system with an optical fiber transmission system. Instead of increasing circuit board density to handle more data, the system converts image data into optical signals transmitted through optical fibers, which do not suffer from electromagnetic wave interference or signal noise, thereby maintaining high data transmission capacity without the harmful effects of dense electrical circuits.
3Productivity
If multilayer board design is used to increase data transmission capacity, then transmission capacity is improved, but thermal effect and product lifetime are worsened
Solution Approach 1:
The patent replaces the electrical multilayer board transmission system with an optical fiber transmission system. Optical fibers transmit data as light signals without generating significant heat, eliminating the thermal effects that limit the lifetime of electrical circuit boards. This substitution maintains high data transmission capacity while avoiding thermal degradation and extending product lifetime.
4Power
If flash device is used to transmit large current, then power delivery is improved, but signal transmission is interfered with causing noise and delay
Solution Approach 1:
The patent substitutes electrical current transmission through flash devices with optical signal transmission through optical fibers. Optical signals are not affected by electromagnetic interference from large currents, eliminating signal noise and transmission delays that occur when flash devices are used to deliver power in electrical systems.
