Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the laser leveling device is moved continuously to complete complex layouts, then the reference laser lines can be extended, but the layout process becomes disrupted and time-consuming

Engineering Contradiction:

Improvelayout completion speedVSAvoidoperation continuity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The device divides the layout task into two independent functions: (1) a stationary reference laser system that establishes fixed reference lines, and (2) a mobile measurement system with distance measuring lasers that can be positioned at different locations. This segmentation allows the reference lines to remain continuous while measurements can be taken at multiple positions without moving the reference system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces distance measuring lasers as an intermediary tool between the stationary reference laser system and the user. These distance measuring lasers project measurement beams that can be interrupted by a handheld display or target, allowing distance measurements to be taken from various positions along the reference lines without moving the reference laser device itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the reference laser lines are interrupted to measure distances, then distance measurements can be taken, but the reference lines are disrupted

Engineering Contradiction:

Improvedistance measurement accuracyVSAvoidreference line continuity

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The laser system is segmented into two independent laser beams: (1) reference laser lines that provide continuous horizontal and vertical references, and (2) distance measuring lasers that are used temporarily for measurement purposes. The distance measuring lasers can be interrupted by handheld displays or targets without affecting the continuous reference lines, as they operate independently.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the laser system have different functional qualities: the reference laser system provides continuous, uninterrupted reference lines for alignment, while the distance measuring lasers provide temporary, interruptible measurement beams. Each laser component is optimized for its specific function, allowing distance measurements to be taken locally without disrupting the overall reference system.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple distance measuring lasers are used at predetermined angles, then comprehensive distance measurements can be taken from a single position, but the device complexity increases

Engineering Contradiction:

Improvemeasurement coverageVSAvoidlaser system configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple distance measuring lasers into a single base unit that can perform multiple measurement functions. The base contains several distance measuring lasers positioned at predetermined angles (e.g., 0°, 45°, 90°), allowing the device to measure distances in multiple directions from a single location. This multi-functionality is achieved within a unified device structure, avoiding the need for multiple separate measurement devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)
