Mechanical Apparatus TRIZ Cases

Weather and agency inputs let the thermostat switch heating or cooling in advance, improving convenient and reliable home temperature control.

Stacked substrate treatment lines enable parallel processing to raise throughput without enlarging footprint or compromising clean transport areas.

Using the condenser motor as an electrical load dissipates backspin power from the compressor and prevents damaging voltage spikes in HVAC systems.

Periodic diffusion cycles and sensor feedback balance dispersal and decay to maintain target scent concentration without user fatigue.

Local temperature feedback adjusts injector flow across plate passages to maintain uniform evaporation and avoid part-load malfunctions.

A blinking light and adjustable range stop help verify damper position and simplify HVAC actuator installation in insulated ducts.

Axial airflow and an anodized aluminum housing improve cooling, EMI shielding, and rigidity in a compact desktop computer.

Dual-sided evaporator heating cuts defrost time and keeps supply air stable by combining hot refrigerant flow with reduced heat recovery.

Pre-modeled operating points and feedback control cut chiller plant room energy use despite changing cooling loads and weather.

Feedback control of fan speed, dampers, and nozzles maintains exhaust pressure and velocity to cut energy waste and prevent fume re-entrainment.

A thermostat applies an offset to sensed temperature, cutting HVAC peak-demand operation without changing the user-set temperature.

Flush ceiling infrared radiant panels heat clean rooms evenly while minimizing air turbulence and preserving stable laminar airflow.

Soft elastic flap attachments damp flap motion in a self-adjusting cold air outlet, cutting noise while keeping airflow stable.

Using only outdoor temperature, current, and voltage sensing, this case detects low-efficiency HVAC operation and predicts failures without indoor sensors.

Periodic wake-up bidirectional communication lets the remote display operation time, power use, and louver direction without draining battery.

Using discharge-line and condenser temperatures with voltage and current sensing, this case enables low-cost remote HVAC fault diagnosis before failure.

Switching between comfort and economy modes lets an HVAC controller use local energy when available while preserving reliable building comfort.

Thermal load estimation adjusts compressor speed and fan operation to stabilize cabin temperature while cutting power loss from compressor cycling.

A pass variable tube and segmented outdoor heat exchanger improve refrigerant distribution, heat exchange time, and pressure control in heating.

By changing expansion settings and comparing sensor responses to expected patterns, wire connections can be identified without rewiring.

A helical flash tank with a central auger separates CO2 vapor and liquid under vibration, improving compact mobile transcritical cooling.
