Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual arrangement of arrangement targets is performed in the virtual space, then positioning accuracy can be achieved, but time and labor expenditure increase significantly

Engineering Contradiction:
Improvepositioning accuracyVSAvoidtime and labor expenditure
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service arrangement by allowing the work machine to automatically position arrangement targets based on its own movement and work information, eliminating the need for manual positioning while maintaining accuracy through the machine's operational data

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical positioning with an automated information processing system that uses the work machine's movement data, work information, and virtual space coordinates to automatically determine and set the positions of arrangement targets

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

2Productivity

If automated arrangement assistance is implemented, then time and labor are reduced, but system complexity increases

Engineering Contradiction:
Improvearrangement efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The work machine performs multiple functions: it executes construction work while simultaneously collecting movement information, work information, and position data that are used for automated arrangement assistance, eliminating the need for separate positioning systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a virtual space as an intermediary layer that stores and processes work information, movement data, and position coordinates, serving as a mediator between the physical work machine and the arrangement assistance function

Inventive Principle:
Principle #24Intermediary (Mediator)
