Solution Overview

Problem

Existing grease nipples lack efficient and reliable methods for tracking lubrication processes, particularly in scenarios with multiple lubrication points close together, leading to potential mix-ups and inefficiencies in maintenance recording.

Innovation Solution

Integration of an RFID transponder within a ring groove in the key handle of the grease nipple, allowing for wireless communication with a reading device to record lubrication data, ensuring accurate tracking of lubrication points and times without manual assembly or special operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If an RFID transponder is integrated into the grease nipple, then lubrication process tracking precision is improved, but device complexity increases

Engineering Contradiction:
Improvelubrication process tracking precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The RFID transponder is merged with the grease nipple by integrating it into the key handle, creating a single unified component. This combination eliminates the need for separate transponder installation while enabling precise lubrication tracking, thus resolving the contradiction between tracking precision and device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The annular RFID transponder is nested within the key handle structure, specifically positioned in a groove that accommodates it. This nesting approach allows the transponder to be housed within the existing grease nipple geometry, adding tracking capability without significantly increasing overall device complexity

Inventive Principle:
Principle #7Nested doll (Nesting)

2Measurement precision

If multiple lubrication points are tracked separately, then lubrication point identification accuracy is improved, but time consumption increases

Engineering Contradiction:
Improvelubrication point identification accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The manual process of recording lubrication points is replaced with automated RFID wireless communication. The read head automatically detects and records the transponder identifier, eliminating manual writing or data entry time while maintaining accurate identification of lubrication points

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs automatic identification and recording of lubrication points through the RFID transponder and read head combination. The process is self-acting during the lubrication operation, requiring no additional time from the operator beyond the normal lubrication task itself

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manual assembly of transponders is required, then manufacturing precision is improved, but productivity decreases

Engineering Contradiction:
Improvetransponder assembly precisionVSAvoidmanufacturing productivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The transponder is pre-integrated into the key handle during the molding process itself, rather than being assembled afterward. This preliminary integration ensures proper positioning and secure mounting while enabling high-speed automated manufacturing, thus improving both precision and productivity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manufacturing process transitions from manual assembly to automated injection molding, changing the production parameter from labor-intensive to machine-intensive. This parameter change enables high-volume production with consistent precision, resolving the contradiction between manufacturing precision and productivity

Inventive Principle:
Principle #35Parameter changes
