Printed Circuit Details TRIZ Cases
- RF Module Filter Stacking With Inner-Space Terminal Connection
A conductive link between opposed transmit and receive filters shortens the common path to reduce transmission loss, coupling, and heat buildup.
- Vehicle Switch Panel With Focused Optical Finger Sensing
Focused optical sensing with a lens improves finger recognition accuracy in compact vehicle switch panels under harsh conditions.
- Vehicle Actuation Unit Assembly With Elastic Inductive Target
An elastic metallic target compressed between housing and support keeps inductive sensor alignment stable despite assembly tolerances.
- Modular Circuit Board Switch Detection via Marked Potential
A shared marked-potential scheme lets interchangeable modular circuit boards detect mistaken switch triggering without hardware or firmware changes.
- RF Module 3D Interconnection Layout for Lower Mismatching Loss
A bridging component spans separated RF parts to shorten interconnects, cut wiring loss and noise, and support smaller module layouts.
- Metal Mesh Breakpoint Compensation for Lower Display Visibility
An insulated compensating line segment beside metal mesh breakpoints cuts their visual impact while preserving sensing function and low-cost fabrication.
- Flexible PCB Pressure Sensor Using a Ceramic Capacitor Stack
A flexible PCB, ceramic capacitor stack, and soft conductive pad simplify pressure sensor assembly while maintaining reliable capacitance sensing.
- Wideband RF Amplifier Bias Circuit for Baseband Resonance
Distributed inductors and capacitors in baseband and harmonic decoupling circuits widen RF amplifier bias response while improving linearity.
