Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional high lift jack is used, then the basic lifting function is provided, but the flexibility and versatility in various applications are limited

Engineering Contradiction:

Improveflexibility in use and applicationVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The service accessory is designed with multiple working surfaces (first, second, third, and fourth working surfaces) that can be presented at different service orientations relative to the jack beam through various assembly configurations. This allows a single accessory to perform multiple functions including lifting, spreading, clamping, and winching operations, thereby improving adaptability without requiring multiple separate tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The service accessory incorporates separate guide structures (first elongate guide and second elongate guide) that can be selectively positioned to create different assembly configurations. This segmentation allows the accessory body to be oriented in multiple ways relative to the jack beam, enabling versatile applications while maintaining a relatively simple overall structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple service orientations are provided, then the versatility for different applications is improved, but the device complexity increases

Engineering Contradiction:

Improveservice orientationsVSAvoidaccessory structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple guide structures (first elongate guide and second elongate guide) are integrated into a single service accessory body rather than being separate components. This merging allows the accessory to achieve multiple assembly configurations and service orientations while maintaining a unified, relatively simple structure that does not require complex assembly mechanisms

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A jack assembly includes a jack, and a service accessory including a plurality of different working surfaces defining a plurality of different service orientations. The service accessory includes a first elongate guide structured to mate the service accessory to the jack beam in a first assembly configuration presenting some of the working surfaces at first service orientations relative to a jack beam, and a second elongate guide structured to mate the service accessory in a second assembly configuration presenting some of the working surfaces at second service orientations relative to the jack beam.
