Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual methods are used to locate vectors by holding bushings in place, then the device complexity is reduced, but the measurement precision deteriorates (accuracy of approximately fifteen thousandths of an inch)
Solution Approach 1:
The patent replaces manual mechanical positioning with an optical measurement system (laser tracker) to achieve high-precision vector location. The laser tracker optically measures the positions of tracker objects at two different orientations to calculate the precise vector location, eliminating the need for manual bushing placement while achieving accuracy of one thousandth of an inch or better.
2Manufacturing precision
If machined hard tooling is used to locate vectors, then the manufacturing precision is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces complex machined hard tooling with a measurement-based optical system. Instead of manufacturing precision tooling fixtures, the system uses a laser tracker to measure and calculate vector locations, significantly reducing device complexity and manufacturing cost while maintaining high precision.
Solution Approach 2:
The patent creates a virtual model of the vector location through optical measurement and calculation rather than using physical hard tooling. The laser tracker captures spatial coordinates and computes the vector position, effectively copying the location information into digital form for processing and reproduction.
3Manufacturing precision
If machined hard tooling is used to locate vectors, then the manufacturing precision is improved, but the loss of time increases due to design and manufacturing requirements
Solution Approach 1:
The patent performs the vector location measurement directly on the part or tool in its final position using the laser tracker, eliminating the need for preliminary design and manufacturing of hard tooling fixtures. The measurement process itself establishes the precise vector location without requiring pre-fabricated positioning equipment.
4Device complexity
If manual methods are used to locate vectors, then the device complexity is reduced, but the productivity deteriorates due to time-consuming operations
Solution Approach 1:
The patent replaces time-consuming manual operations with an automated optical measurement system. The laser tracker automatically captures coordinates and calculates vector positions, dramatically improving productivity while keeping the device setup relatively simple.

AI summary
In one embodiment, a spatial vector locator device includes a first tracker object, a first restraint, and a first bushing. The spatial vector locator device further includes a second tracker object, a second restraint, and a second bushing. A first reference point on the first tracker object is aligned with a vector to determine a first vector point along the vector. A second reference point on the second tracker object is aligned with the vector to determine a second vector point along the vector. An alignment rod is inserted through a first hole of the first bushing and a second hole of the second bushing to physically locate the vector in space.
