Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If absolute data is recorded on scales without embedded identification codes, then the data structure is simple, but it becomes impossible to identify which scale the data belongs to when multiple scales are used

Engineering Contradiction:

Improvescale identification informationVSAvoiddata structure complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the scale ID and position data into a single integrated absolute data value. The detector reads this combined data directly from the scale, eliminating the need for separate identification mechanisms while maintaining the ability to distinguish between multiple scales.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The absolute data serves multiple functions simultaneously: it provides both the scale identification information and the position information. This multi-functional approach eliminates the need for separate data structures for identification and positioning.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If separate identification systems are added to scales, then scale identification becomes possible, but the device complexity and data processing requirements increase

Engineering Contradiction:

Improvescale identification accuracyVSAvoiddetection system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The scale ID and position data are merged into a single absolute data value that is directly readable by the detector. This eliminates the need for separate identification systems while maintaining reliable scale identification.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If external tables or complex calculations are used to extract scale ID and position data, then accurate position detection is achieved, but processing time and computational requirements increase

Engineering Contradiction:

Improveposition detection accuracyVSAvoiddata processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts the scale ID and position data as direct components of the absolute data structure itself. The extractor unit separates these elements from the combined absolute data through simple operations, eliminating the need for complex external tables or iterative calculations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The scale ID and position data are pre-structured within the absolute data value in a format that allows for rapid extraction. This preliminary organization of data enables quick retrieval without requiring complex processing during operation.

Inventive Principle:

Principle #10Preliminary action

AI summary

Data is utilized more efficiently and effectively. A position detection device includes a plurality of scales that each record absolute data embedded with a scale ID for identifying a scale, a detector that detects the absolute data from each of the plurality of scales, and an extractor that extracts, from the detected absolute data, the scale ID and position data representing the position of the scale.
