Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a single screw adjustment mechanism is used, then the structure is simple, but the adjustment speed is slow

Engineering Contradiction:
Improveadjustment speedVSAvoidstructure complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent combines two screw adjustment mechanisms into a single integrated structure. The first screw adjusts the distance between the first and second connection ears, while the second screw adjusts the distance between the third and fourth connection ears simultaneously. This merging of adjustment functions into one structural unit doubles the adjustment speed compared to single-screw mechanisms, while maintaining structural simplicity through the symmetrical arrangement of components.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If pins are used for connection, then the structure is stable, but the overall structure becomes complex

Engineering Contradiction:
Improvestructural stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the pin connection components from the structure. Instead of using pins to connect the connection ears, the design employs direct bolted connections between the first and second connection ears, and between the third and fourth connection ears. This removal of unnecessary pin components simplifies the overall structure while maintaining structural stability through the rigid bolted joints and the symmetrical arrangement of the connection ears.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the cervical collar has a fixed shape, then the structure is simple, but the ergonomics and adaptability are poor

Engineering Contradiction:
Improveergonomic adaptabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic adjustability to the cervical collar structure through two independent screw mechanisms. The first screw mechanism dynamically adjusts the distance between the first and second connection ears, while the second screw mechanism dynamically adjusts the distance between the third and fourth connection ears. This dynamic adjustment capability allows the collar to adapt to different neck sizes and ergonomic requirements, transforming a static structure into a dynamically adjustable one that maintains simplicity through systematic design.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If multiple adjustment mechanisms are added to improve ergonomics, then the adaptability improves, but the adjustment speed decreases

Engineering Contradiction:
Improveergonomic adaptabilityVSAvoidadjustment speed
Core Design Contradiction:
Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent segments the adjustment functions into two independent but symmetrical screw mechanisms. Each screw mechanism handles a specific adjustment task (first screw for first-second connection ear distance, second screw for third-fourth connection ear distance), allowing for specialized optimization of each segment. This segmentation enables both mechanisms to operate simultaneously and efficiently, maintaining fast adjustment speed while providing comprehensive ergonomic adaptability through the divided functional responsibilities.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention belongs to the technical field of cervical collar, especially refers to a fast adjustable simple cervical collar, including a sponge body and an adjusting bracket located inside the sponge body; the adjusting bracket includes an upper bracket and a lower bracket, the upper bracket and lower bracket realizes distance and angle adjustment between the upper bracket and lower bracket via cooperation of upper bolts, lower bolts and threaded bushings. The adjustment of the cervical collar is faster by adopting the double-bolt structure, which doubles the speed of single-bolt adjustment, and it also realizes adjustment of inclination degree of the cervical collar on left and right sides and height between an upper-layer body and a lower-layer body.
