Time Integral Measurement TRIZ Cases
- Self-Locking Wire Retention in Meter Housing Supports
A self-locking washer, pin, and wall structure secures meter wires in a compact housing while cutting parts, bulk, and assembly steps.
- Segmented Electric Meter Housing for Live Maintenance Access
A removable outer cover gives access to meter internals without breaking the socket seal, avoiding service interruption and line-voltage exposure.
- Compact Power Meter Terminal Bus Bar Guide Integration
Integrated guide ribs and bus bars secure line conductor lugs to prevent tampering while ensuring accurate current sensing.
- Socket-Jaw Protection Module for Electric Meter Installation
An integrated sensor measures clamping force during installation to prevent hot sockets, eliminating the need for external inspection tools.
- Oblique Inductive Component Mounting for Magnetic Immunity
Orienting the winding axis obliquely breaks symmetry against magnets, preventing fraud while keeping the meter size and cost low.
- Adjustable Meter Box Grounding Clamp for Varying Conductor Sizes
A coupling member adjusts the distance between arms to accommodate varying conductor dimensions without complex rigid adjustments.
- Electricity Meter Connector with Neutral Conductor Integration
An elongated housing integrates a neutral conductor element to resolve size and material cost trade-offs in single-phase electricity meter applications.
- Dual Firmware Architecture for Energy Meters
Segmenting firmware into updateable and non-updatable modules allows device updates without triggering re-approval of the calibrated measurement core.
- Electricity Meter Tamper Detection Circuit
Tamper detection circuit monitors power interruptions to identify meter removal from the socket.
- Three-Phase Meter Power Estimation via Neutral Wire Voltage
A three-phase meter estimates power using neutral wire voltage and unaffected phase data.
- Electric Meter Rear Access for Fraud Prevention
Segmented housing places upstream connectors on the rear face to block customer manipulation, resolving security versus maintenance trade-offs.
- Bypass Detection Module for Utility Meter Remote Monitoring
A bypass detection module monitors line and load side voltages to identify unauthorized service connections.
- Segmented Power Metering System for Cost-Effective Upgrades
Segmenting the system into a basic meter and a detachable diagnostic module resolves the cost-versus-adaptability trade-off in power monitoring infrastructure.
- Fracturable Retainer Locking System for Utility Meter Enclosures
A fracturable retainer secures utility meter enclosures by blocking engagement between interlocking gear teeth until a special tool breaks the seal.
- Lever-Arm Cover Removal Switch for Utility Meters
A pivoting lever arm actuates a switch element when a meter cover is removed.
- Electricity Meter Housing with Tool-Activated Unlocking
Unlocking openings allow authorized tools to shift locking elements out of position for maintenance while the cover prevents unauthorized access.
- Electricity Meter Housing with Internal Locking and External Release
Internal connecting elements form a detent connection via translational movement, eliminating angular positioning requirements for secure assembly.
- Electric Meter Fraud Detection Witness Mechanism
A magnetic witness indicator undergoes irreversible displacement when exposed to external fields, providing physical proof of tampering.
- Magnetic Tamper Detection in Utility Meters
Continuous digital monitoring of magnetic field strength identifies low-level tampering that threshold systems miss.
- Fraud Detection in Electricity Networks via Data Concentrator Analysis
A data concentrator calculates cumulative energy ratios to identify network fraud without modifying individual meters.
- Electricity Meter Clock Accuracy Measurement via Optical Port
Optical signal conversion enables 1 ppm clock accuracy measurement without opening the sealed meter housing.
