Circuit Bendability/Stretchability TRIZ Cases

Two independently programmable power management chips share display driving load to support demanding panels while lowering PCB temperature.

A non-metallic central stiffener helps a folded flexible PCB battery absorb shock and vibration while protecting cells and reducing weight.

A bridge film extends COF fan-out beyond the base film, cutting display dead space while supporting thin, bezel-less panel assembly.

A loop antenna routed through the rims and bridge frees temple space, lowers SAR near the body, and improves wireless radiation efficiency.

Varying titanium thickness across wiring regions balances tensile and compressive stress, reducing line disconnection on curved flexible substrates.

Directly welding multilayer copper film portions on the FPC to the busbar removes nickel tabs, prevents sagging, and improves joint reliability.

Large-diameter fibrous carbon and conductive carbon black enable coatable conductive films that keep resistance low during expansion.

A coverlay opening lets condensation drain from the joint region, improving moisture resistance without lowering flexible substrate yield.

Mounting a flexible substrate along an instrument panel reinforcement stabilizes wire harness assembly, saves space, and cuts substrate use.

Spacers between stacked signal strips cut parasitic capacitance in bundled flexible cables, preserving high-frequency insertion and return loss.

Selective extruded coatings reinforce high-wear flex-circuit zones to reduce abrasion, kinking, and electrical noise without losing flexibility.

Overlapping repulsive sensing magnets and Hall detection improve zoom position accuracy in a compact folded telephoto lens module.

A unified FPC and antenna substrate removes solder joints, limits magnetic interference, and prevents connection and foil wrinkle defects.

A conductive housing side member replaces antenna modules, freeing space in large-display foldable electronics while maintaining wireless links.

Continuous via-linked windings in a cylindrical flexible board laminate cut coil joins, heat, and motor manufacturing complexity.

Back-surface legs on the wiring board absorb flat-surface loads, protecting control unit connectors during maintenance and handling.

A bendable board extension replaces cables and connectors to match impedance, cut reflection loss, and support high-speed package signals.

By placing conductive vias only in rigid sections and tuning dielectric layers, this rigid-flex PCB avoids bending cracks and cuts board thickness.

A multilayer PCB uses tuned ground, signal, and dielectric layers to block target-band power noise without extra decoupling components.

Serpentine conductors and redundancy members absorb garment strain to prevent sensor cracking and preserve accurate athletic motion data.

A bent flexible film routes LED connection leads around substrate edges to cut bezel width while reducing stress and breakage during assembly.
