Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If mechanical or non-electrical means are used for measurements, then the system simplicity is improved, but the measurement precision deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidangle accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical measurement methods with a geometric construction system using three cables of specific lengths (40ft, 20ft, 44ft 11/16in) connected to stakes. This mechanical geometry system achieves precise 90-degree angles through mathematical relationships between cable lengths, eliminating the need for electronic devices while maintaining high measurement precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the parameters of the measurement system by using specific cable lengths that form a right triangle (3-4-5 ratio scaled up). The cables are arranged so that when taut, they create precise 90-degree angles at the corner stake, transforming the measurement problem into a geometric configuration problem with known solutions.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If trial and error methods are used to form ninety degree angles, then the ease of operation is improved, but the time consumption increases

Engineering Contradiction:

Improveease of angle formationVSAvoidtime consumption

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-calculating and pre-configuring the three cables with specific lengths before use. The cables are prepared in advance with the correct dimensions to form a right triangle, so that when deployed, they immediately establish accurate 90-degree angles without requiring trial and error adjustments during the actual measurement process.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If electronic devices are used for measurements, then the measurement precision is improved, but the device complexity increases

Engineering Contradiction:

Improveangle accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent substitutes electronic measurement devices with a purely mechanical geometric system. Three cables of predetermined lengths are connected to stakes and pulled taut to form a right triangle, creating 90-degree angles through geometric principles rather than electronic computation. This eliminates electronic complexity while achieving the same measurement precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
