Propulsion By Humans/Animals TRIZ Cases

Resistive torque is adjusted from estimated pedal power to avoid sensor lag and keep pedaling smooth and comfortable at high speeds.

A radially offset hub interface combines torque support and electrical coupling to simplify assembly and protect wiring from damage.

Integrated switches and wireless units on the battery holder shorten e-bike control wiring while keeping battery replacement and operation easy.

Wheel movement sensed by a dynamo wakes the battery automatically, avoiding confusing manual startup on shared scooters and bikes.

Selective charging targets the most efficient e-bike battery to extend range, preserve battery life, and limit switching power loss.

A can-mounted guard slows and redirects leakage at the case-end lid joint, lowering short-circuit fire risk in battery cells.

A can-mounted guard covers the case-lid joint, slows electrolyte leakage, and guides it to an outlet to reduce short-circuit fire risk.

Battery packs share internal state and transfer output authority locally, cutting controller load while keeping EV power delivery stable.

Delaying second-motor assist until speed difference falls below a threshold restores smooth pedaling recovery and protects the target speed ratio.

Arc-transition casing geometry and layered insulators keep the electrode assembly close to the wall while preventing wrinkling and internal shorts.

A detachable auxiliary battery connects in series with the main e-bike battery to extend range when needed without carrying extra weight on short rides.

A linked hood and battery lock enables one-step battery removal while reducing vibration, contact wear, water ingress, and hinge stress.

Closed-loop control stabilizes intermediate circuit voltage by matching e-drive power to fluctuating generator output in battery-free cargo e-bikes.

A radially offset hub interface combines torque support and electrical coupling to protect the connection and simplify bicycle hub mounting.

A base-mounted switch, wireless link, and battery lock shorten wiring while keeping motor assist controls easy to reach.

A wheel-mounted dynamo detects movement and signals battery wake-up, removing confusing manual activation on shared scooters and bikes.

Compact electric cycle propulsion unit integrates electronics inside the housing to dissipate heat via an intermediate element, reducing bulk and weight.

A control unit processes drawbar load data to activate an electric motor, maintaining tensile stress below a fatigue threshold.

GPS tracking and tamper-proof mechanisms prevent unauthorized removal of electric vehicle battery packs.

Segmenting the frame into separable modules with integrated wiring channels resolves the contradiction between aesthetic integration and ease of repair.
