Solution Overview

Problem

Existing ABS unit attachment structures that use floating support via vibration absorbing members do not sufficiently suppress vibrations, leading to unsatisfied vibration conditions and restricted layout options for the ABS unit.

Innovation Solution

An ABS unit attachment structure that includes a floating bracket supported by a vehicle body frame via vibration absorbing members, with an additional weight attached to the bracket to increase the total supported weight, thereby reducing vibration transmission to the ABS unit, and allowing for increased layout flexibility by sharing the floating bracket with other components like the exhaust valve actuator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the ABS unit is supported by a vehicle body frame in a floated manner via vibration absorbing members, then vibration from the vehicle body frame is absorbed, but the vibration suppression is insufficient and layout options are restricted

Engineering Contradiction:

Improvevibration transmission to ABS unitVSAvoidlayout flexibility of ABS unit

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent combines the ABS unit bracket with the exhaust valve actuator bracket into a single integrated bracket structure. This merging allows the ABS unit to share the same mounting location and support structure as the exhaust valve actuator, thereby increasing layout flexibility without compromising vibration suppression. The integrated bracket is supported by the vehicle body frame in a floated manner via vibration absorbing members, providing sufficient vibration isolation for both mounted components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bracket structure serves multiple functions: it mounts the ABS unit, mounts the exhaust valve actuator, and provides vibration isolation through floated support via vibration absorbing members. By making the bracket multi-functional, the patent eliminates the need for separate brackets and mounting structures, thereby increasing layout flexibility and reducing the number of components while maintaining effective vibration suppression.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If a separate bracket is provided for the exhaust valve actuator, then the actuator can be mounted, but the number of components increases and weight increases

Engineering Contradiction:

Improvecomponent assemblyVSAvoidtotal weight of bracket system

Core Design Contradiction:

Ease of manufactureVSWeight of moving object

Solution Approach 1:

The patent merges the ABS unit bracket and exhaust valve actuator bracket into a single integrated bracket structure. This eliminates the need for separate brackets and reduces the total number of components. The integrated design reduces overall weight while simplifying assembly, as both components are mounted to the same bracket structure that is already supported by the vehicle body frame.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the ABS unit is mounted at locations with high vibration transmission, then layout freedom is increased, but vibration conditions for the ABS unit are not satisfied

Engineering Contradiction:

Improvelayout freedom of ABS unitVSAvoidvibration condition satisfaction of ABS unit

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces vibration absorbing members as an intermediary between the vehicle body frame and the integrated bracket. These members provide floated support that absorbs vibrations from the vehicle body frame before they reach the ABS unit and exhaust valve actuator. This intermediary mechanism enables the ABS unit to be mounted in locations with greater layout freedom while still satisfying vibration conditions through effective vibration isolation.

Inventive Principle:

Principle #24Intermediary (Mediator)
