Transformers/Inductances Details TRIZ Cases
- Rectangular Wound Core Structure for Low-Noise Tight Bending
By tuning bend radius and interlaminar friction in grain-oriented steel laminations, this case cuts wound core noise without losing shape precision.
- Wound Core Grain Orientation Control for Lower Iron Loss
Controlled grain orientation near bent portions cuts bending-induced iron loss in wound cores while preserving shape and magnetic performance.
- Conductor Body Encapsulation Using a Carrier Body for Precise Positioning
A carrier body prepositions the conductor body before injection molding, enabling precise shape control with lower production complexity.
- Spring-Loaded Plug-In Insulation to Minimize Air Gaps
A sliding element and spring keep insulating material pressed against the receiving device, reducing air gaps and arcing during temperature changes.
- Coil Magnetic Base Body With Si-Rich Particle Surfaces
Si-rich particle surfaces and Si-O precipitates limit Fe oxidation while preserving oxide-film insulation and magnetic permeability in coil components.
- Coil Lead-Out Structure for Lower Magnetic Resistance
Offset lead-out shaft portions create more flux margin in a compact coil component, reducing magnetic resistance and improving DC superposition.
- Transformer Wound Core Bending With Controlled Subgrain Boundaries
Controlled subgrain boundaries near small-radius bends help wound transformer cores limit iron loss without post-bending annealing.
- Soft Magnetic Alloy Nanocrystal Control for High Bs and Low He
Controlled nanocrystal size and circularity balance high saturation flux density with low coercivity in soft magnetic cores and components.
- Tapered Inductor Core Structure for Accurate Electronic Pen Detection
A tapered tubular inductor core with controlled pore distribution improves electronic pen position detection while reducing surface damage.
- Transformer Coil Filling Layer for Magnetic Flux Conduction
A magnetizable filling layer between the core and coil replaces air gaps, improving flux conduction while reducing electrical steel use and cost.
- Electrical Bushing Anti-Rotation Flange for Fast Transformer Mounting
A locking flange engages a recess on the bushing body to stop post-installation rotation without adhesives, easing transformer assembly and service.
- Overlapped Multilayer Magnetic Sheet to Prevent Flux Leakage
Overlapping laminate substrates remove continuous magnetic gaps, cutting stacking work while preserving permeability, Q factor, and flux shielding.
- Silicon Steel Coating Uniformity for Low-Loss, Low-Noise Transformers
Controlled magnesium silicate reflectivity and gloss uniformity cut iron loss and magnetostriction, lowering transformer vibration noise.
- Amorphous Soft Magnetic Powder for Low Core Loss at High Frequency
Optimized Fe-Si-B amorphous powder composition lowers coercive force while preserving permeability, reducing high-frequency core loss.
- Power Bushing Sealing Arrangement for Thermal Movement and Oil Tightness
A guide element separates static and dynamic seals so a power bushing stays oil-tight during thermal expansion while reducing wear and eccentricity.
- Ceramic-Coated Soft Magnetic Powder With Crack-Resistant Insulating Film
Two-stage mechanical compression bonds ceramic powder into a uniform insulating film that resists peeling, lowers binder use, and cuts eddy current loss.
- Wound Core Bending Hardness Control for Lower Iron Loss
Controlling bending stress, friction, and bent-part hardness keeps plastic strain in wound cores low and reduces iron loss even without annealing.
- Heated Bending of Coated Wound Cores to Suppress Iron Loss
Heating coated grain-oriented steel during bending preserves coating soundness and limits deformation twins, reducing iron loss in wound cores.
