Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a laser level is manually held and adjusted by an operator, then the device is simple and portable, but the operator becomes fatigued and measurement precision deteriorates over time

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

Solution Approach 1:

The patent applies dynamics by making the bracket system movable rather than fixed. The movable bracket is driven by a motor to automatically adjust the laser level's position and orientation, enabling dynamic tracking and leveling without manual intervention. This resolves the contradiction by eliminating operator fatigue while maintaining measurement precision through automated positional adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The laser level assembly performs self-service through automated functions. The motor-driven movable bracket automatically adjusts the laser level position, and the level assembly self-corrects its orientation using integrated sensors and control mechanisms. This eliminates the need for continuous manual adjustment, maintaining precision without increasing operational complexity.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If a laser level is mounted on a fixed bracket, then the structure is simple, but the device cannot adapt to different positioning requirements

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

Solution Approach 1:

The bracket is designed as a movable structure driven by a motor, allowing the laser level to be dynamically repositioned to various locations and angles. This dynamic capability provides adaptability to different positioning requirements while the motorized control system manages the complexity through automated operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable bracket system provides multi-functionality by enabling the laser level to perform multiple positioning tasks. The same bracket mechanism can adjust position, orientation, and elevation, making the device universally adaptable to various measurement scenarios without requiring multiple separate devices.

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

3Productivity

If manual adjustment mechanisms are used, then the device is simple, but productivity and measurement speed are reduced

Engineering Contradiction:
Improvemeasurement speedVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical adjustment with an automated motor-driven system. The motor automatically positions the movable bracket and adjusts the laser level orientation, eliminating the need for manual manipulation. This substitution significantly increases measurement speed and productivity while the automated control system manages the added mechanical complexity.

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

4Stability of the object's composition

If the laser level is held manually, then no mounting structure is needed, but operator fatigue increases and stability decreases

Engineering Contradiction:
Improvemeasurement stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The motor-driven movable bracket provides dynamic stabilization by automatically adjusting the laser level position to maintain optimal measurement conditions. The system compensates for disturbances and maintains stability without manual intervention, resolving the contradiction between stability and the simplicity of manual holding.

Inventive Principle:
Principle #15Dynamics

AI summary

A laser level assembly comprises a mounting bracket comprising an attachment bracket and a movable bracket. A laser level is mounted on the movable bracket, the laser level configured to project at least one of a horizontal line, a vertical line, or a laser spot. There is a motor in the movable bracket, and a clutch is operatively associated with the motor. The motor is configured to drive movement of the movable bracket relative to the attachment bracket.
