Solution Overview

Problem

Existing bearing designs face limitations in design freedom due to installation processes, require complex constructions, and are not suitable for thin metal sheets, as they often rely on separate fixation and decoupling mechanisms, and cannot effectively handle radial forces on both sides.

Innovation Solution

A bearing design featuring two bearing parts with radially biased pins that interlock via form or friction fit, allowing for vibration-insulating mounting on thin metal sheets with radial force distribution, using a single fastening means and eliminating the need for multiple screws, with optional elastomer ribs and stiffening rings for enhanced fixation and decoupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the holding structure is pressed through the hole on the side facing away from the buffer, then the bearing can be installed, but the holding structure cannot be designed to be as large as desired, limiting design freedom

Engineering Contradiction:
Improvedesign freedomVSAvoidinstallation process constraint
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of pressing the holding structure through the hole from the buffer side (conventional approach), the invention inverts the sequence by first inserting pins through the hole from the buffer side, then pressing the holding structure through the same hole to engage with the pins. This inversion allows the holding structure to be designed larger without installation constraints, as the pins provide a guide and support during installation.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If separate fixation and decoupling mechanisms are used, then sufficient decoupling can be ensured, but the construction becomes complex and multiple screw connections are required

Engineering Contradiction:
Improvedecoupling performanceVSAvoidconstruction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention merges the fixation function (pins through the hole) and the decoupling function (holding structure engaging with the pins) into a single integrated mechanism. The pins serve as both fixation elements and guide elements, while the holding structure provides both the decoupling interface and the mounting interface, eliminating the need for separate screw connections and reducing construction complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If the frame must have sufficient thickness for both bearing halves to be held from above and below, then the bearing can be properly installed, but this option does not apply to installation in a hole in a thin metal sheet

Engineering Contradiction:
Improvebearing installation stabilityVSAvoidapplicability to thin metal sheets
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The invention segments the bearing into two distinct parts: a buffer component and a holding structure component, connected by pins. This segmentation allows the buffer to be installed on one side of the thin metal sheet while the holding structure is installed on the other side through the same hole, eliminating the need for a thick frame and enabling installation on thin metal sheets while maintaining installation stability.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If a single fastening means is used with the radially biased pins, then the bearing becomes easier to manufacture and install, but the pins must be designed to provide both fixation and decoupling functions

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidpin design complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The pins are designed as universal elements that perform multiple functions: they provide fixation by passing through the hole and engaging with the holding structure, provide decoupling through their radial bias that allows vibration isolation, and serve as guide elements during installation. This multi-functionality reduces the number of components needed and simplifies manufacturing, despite the increased complexity in the pin's structural design.

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

AI summary

A bearing provides a vibration-insulating mount on a first component with a hole through which a central longitudinal axis extends. The bearing includes a first bearing part with a first fixing structure that can be arranged on one side of the first component, and a second bearing part with a second fixing structure that can be arranged on the other side of the first component. In embodiments, the first fixing structure comprises first pins that can protrude into the hole, and the second fixing structure comprises second pins that can protrude into the hole. In embodiments, at least one of the pins of each fixing structure is biased or is able to be biased radially outwards with respect to the central longitudinal axis.
