Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex positioning structure is used to fix the carrier after rotation, then the carrier can be positioned in different swing directions, but the assembly becomes difficult and cost increases

Engineering Contradiction:

Improvecarrier positioning in different swing directionsVSAvoidpositioning structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The positioning structure is segmented into discrete engaging parts (protrusions) and positioning parts (recesses) distributed around the rotation axis. This segmentation allows the carrier to be positioned at multiple discrete swing directions while using simple, modular components rather than a complex continuous positioning mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elastic protrusions automatically engage with the positioning recesses when the carrier rotates to different positions, providing self-positioning and self-locking functionality. This eliminates the need for complex external positioning mechanisms or manual adjustment devices, reducing overall structure complexity while maintaining versatility.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If a complex positioning structure is used to fix the carrier after rotation, then the carrier can be positioned in different swing directions, but assembly convenience deteriorates

Engineering Contradiction:

Improvecarrier positioning in different swing directionsVSAvoidassembly convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The elastic protrusions automatically engage with the positioning recesses when the carrier rotates to different positions, providing self-positioning and self-locking functionality. This eliminates the need for complex external positioning mechanisms or manual adjustment devices, reducing overall structure complexity while maintaining versatility.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The elastic protrusions are designed to deform elastically during the assembly process, allowing smooth engagement with the positioning recesses. This dynamic flexibility simplifies assembly by eliminating the need for precise manual alignment or complex locking mechanisms, making the assembly process more convenient while still achieving reliable positioning.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple engaging parts and positioning parts are used to fix the carrier after rotation, then the carrier can be positioned in different swing directions, but manufacturing cost increases

Engineering Contradiction:

Improvecarrier positioning in different swing directionsVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The positioning structure is segmented into discrete engaging parts (protrusions) and positioning parts (recesses) distributed around the rotation axis. This segmentation allows the carrier to be positioned at multiple discrete swing directions while using simple, modular components rather than a complex continuous positioning mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The engaging parts and positioning parts are designed as simple, easily manufacturable features that can be integrated into the existing carrier and mounting structure. By using simple geometric features (protrusions and recesses) rather than complex mechanical components, the manufacturing cost is kept low while still achieving the desired positioning functionality in multiple swing directions.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

The present disclosure provides a carrier mounting part disposed on a swing arm rotatably connected to a bracket of a seat. The carrier mounting part includes: a rotating base; and a fixed base. The rotating base is provided with engaging parts, and the fixed base is provided with a positioning part. Alternatively, the rotating base is provided with an engaging part, and the fixed base is provided with positioning parts. One of the rotating base and the fixed base is provided with a side wall, and the side wall is provided with the engaging part or the positioning part. The engaging part or the positioning part disposed on the side wall includes an elastic protrusion. When the rotating base and the fixed base are relatively fixed, the elastic protrusion abuts against the engaging part or the positioning part. The present disclosure also relates to a seat.
