Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a laser level is made rotatable about multiple axes with motor drivers, then positioning precision and flexibility are improved, but device complexity increases

Engineering Contradiction:
Improvepositioning precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The laser level system is divided into multiple independent rotational modules, each controlled by separate motors. The first motor controls rotation about a first axis, while the second motor controls rotation about a second axis. This segmentation allows each motor to independently control one rotational degree of freedom, simplifying the control architecture while achieving precise multi-axis positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The laser level is designed with dynamic rotational capabilities about multiple axes rather than being fixed. The system transitions from a static mounting configuration to a dynamic one where the laser level can be rotated about a first axis and simultaneously rotated about a second axis that is transverse to the first axis, enabling flexible positioning adaptability.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If separate motors are used for each rotational axis, then rotational control precision is improved, but device complexity and component count increase

Engineering Contradiction:
Improverotational control precisionVSAvoidcomponent count
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The rotational control system is segmented into independent motor units, with each motor dedicated to controlling rotation about a specific axis. This segmentation provides precise control for each rotational degree of freedom while maintaining modular architecture that simplifies the overall control system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each motor unit is designed to be universally applicable to its specific rotational axis, with the first motor controlling rotation about the first axis and the second motor controlling rotation about the second axis. This universal design approach allows each motor to perform its specific function optimally while the entire system achieves multi-axis rotational capability.

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

3Adaptability or versatility

If the laser level is made rotatable about two transverse axes, then positioning flexibility and adaptability are improved, but structural complexity increases

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The laser level mounting structure is transformed from static to dynamic by introducing rotational degrees of freedom. The laser level can rotate about a first axis and simultaneously rotate about a second axis that is transverse to the first axis, providing dynamic adaptability for various positioning requirements in construction environments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotational mechanism is segmented into independent rotational joints, with each joint responsible for rotation about a specific axis. This segmentation of the structural system allows for controlled rotation about the first axis and the second transverse axis independently, achieving positioning flexibility while managing structural complexity through modular design.

Inventive Principle:
Principle #1Segmentation
