Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual alignment is used for vehicle parts, then the device complexity is low, but the manufacturing precision and measurement precision are insufficient

Engineering Contradiction:
Improvealignment precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical alignment with an optical measurement system using a laser emitter. The laser provides a precise reference beam that can be accurately aligned with vehicle parts, eliminating the imprecision of manual eye-based alignment while maintaining operational simplicity through intuitive optical reference.

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

Solution Approach 2:

The patent introduces a laser emitter as an intermediary tool between the aligner and the vehicle parts. The laser beam serves as a precise reference mediator that defines the alignment target, allowing for accurate positioning of seats and wheels without requiring complex mechanical alignment devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a fixed laser holder is used, then the device complexity is low, but the adaptability is limited for aligning different vehicle parts

Engineering Contradiction:
Improvealignment flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustability in the laser holder through a pivot arm mechanism with pivot joints. This allows the laser emitter to be positioned in multiple orientations and angles, adapting to different alignment requirements for various vehicle parts such as seats, wheels, and handlebars, while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent divides the laser holder into segmented components including a pivot arm, pivot joints, and adjustable positioning mechanisms. This segmentation allows independent adjustment of each component to achieve the desired laser orientation, providing versatility for aligning different vehicle parts without requiring a completely different device for each application.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If precise alignment of multiple vehicle parts is required, then the measurement precision improves, but the alignment time increases

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent uses a laser-based optical system to rapidly establish precise alignment references compared to traditional mechanical measurement tools. The laser beam provides immediate visual feedback for alignment, reducing the time required to achieve precise positioning of multiple vehicle parts while maintaining high measurement accuracy.

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

Solution Approach 2:

The patent allows for preliminary setup of the laser holder in a standardized position that can be quickly adjusted to different alignment targets. The pivot arm mechanism can be pre-positioned and then rapidly fine-tuned using the pivot joints, enabling efficient sequential alignment of multiple vehicle parts without requiring complete reconfiguration between measurements.

Inventive Principle:
Principle #10Preliminary action
