Solution Overview

Problem

Vehicle engine servicing requires access to various engine components, necessitating a mechanical device to support and elevate the engine relative to the vehicle frame for adequate access, which existing solutions fail to provide efficiently.

Innovation Solution

An engine support system comprising a frame mount with slidably mounted arms and a jack assembly, featuring a coupler that attaches to the engine block, allowing for vertical movement of the engine relative to the frame, enabling secure engagement with the vehicle frame and facilitating access for servicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mechanical device is used to support and elevate the engine, then access to engine components is improved, but device complexity increases

Engineering Contradiction:
Improveaccess to engine componentsVSAvoidmechanical device complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The engine support system is divided into separate functional components: a frame mount with elongated body that attaches to the vehicle frame, a coupler that attaches to the engine, and a jack assembly with movable collar and jack rod. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collar is slidably mounted on the elongated body, allowing the collar to move along the body's length. The jack rod is coupled to the collar and moves perpendicular to the body's longitudinal direction. This nested arrangement enables compact storage when not in use while providing full elevation capability when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the engine is elevated relative to the frame, then servicing access is improved, but stability of engine position may worsen

Engineering Contradiction:
Improveservicing accessVSAvoidengine position stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The collar is designed to be slidable on the elongated body, allowing dynamic adjustment of the engine's horizontal position along the frame. The jack rod provides vertical elevation while the collars' sliding capability enables fine-tuning of the engine's position to achieve both accessibility and stability during servicing operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The flanges on the arms are tapered to increase contact surface area with the frame rails, providing localized enhanced stability at the attachment points while allowing the engine to be elevated and accessed from below.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If slidably mounted arms are used to engage the frame, then adaptability to different frame positions is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to frame positionsVSAvoidarm mounting mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The arms are slidably mounted on the elongated body, allowing them to move horizontally along the body's length. This dynamic capability enables the arms to adapt to different frame rail positions while maintaining a simple structural design without requiring complex adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elongated body serves multiple functions: it provides the mounting structure for the arms, serves as a guide for the sliding collar, and acts as the primary attachment element to the vehicle frame. This multi-functionality reduces overall device complexity while maintaining adaptability.

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