A bearing design featuring a generally cylindrical sidewall with a low friction material and an engagement feature, including a flange and radially extending features, which can be adapted to fit various structures through arcuate or polygonal relief portions, allowing for secure locking without additional flanges and accommodating different thicknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bearing uses a simple cylindrical design without additional installation features, then it is easy to manufacture and has simple structure, but it lacks secure locking capability and adaptability to varying structural thicknesses

Engineering Contradiction:
Improveadaptability to varying structural thicknessesVSAvoidbearing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bearing is divided into distinct functional segments: a cylindrical body portion for rotation, a flange for positioning, and radially extending features for locking. This segmentation allows each part to perform its specific function while maintaining overall simplicity in the manufacturing process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bearing design transitions from a simple two-dimensional cylindrical surface to a three-dimensional structure with radially extending features that protrude outward. This dimensional addition enables secure locking capability without significantly increasing manufacturing complexity, as the features are formed as integral parts of the bearing body.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If a bearing includes additional flanges and complex features for secure locking, then it achieves reliable installation, but it increases manufacturing complexity and production cost

Engineering Contradiction:
Improveinstallation securityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple bearing components are merged into a single integrated structure. The cylindrical body, flange, and radially extending locking features are formed as one piece, eliminating the need for separate parts and assembly steps. This merging maintains installation security while significantly simplifying manufacturing processes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bearing design incorporates multi-functional elements where the radially extending features serve dual purposes: they provide secure locking engagement with the structure and can be used for alignment during installation. This universality reduces the need for additional specialized components, thereby simplifying manufacturing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If a bearing has a simple design without alignment features, then it is easier to manufacture, but it lacks easy alignment and rotation capability during installation

Engineering Contradiction:
Improvealignment and rotation easeVSAvoidbearing feature complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bearing incorporates self-aligning features in the form of radially extending elements that automatically guide the bearing into proper alignment during installation. These features work passively without requiring external alignment tools or complex adjustment mechanisms, thereby improving ease of operation while maintaining manufacturing simplicity.

Inventive Principle:
Principle #25Self-service

AI summary

A bearing can include a generally cylindrical sidewall, a flange extending radially from the generally cylindrical sidewall, and a feature extending radially from the generally cylindrical sidewall at a location disposed a distance from the flange. An assembly can include the beating and a structure having an opening with a relief portion adapted to receive the feature.
