Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a manual lifting mechanism is used to adjust the height of the top part, then the structure can be simple, but the operation becomes labor-intensive and inconvenient

Engineering Contradiction:
Improvestructure complexityVSAvoidoperation convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent replaces the traditional manual mechanical lifting mechanism with an electric motor-driven lifting mechanism. The motor automatically lifts the top part without requiring manual force, thereby maintaining structural simplicity while dramatically improving ease of operation. The motorized system eliminates the need for users to physically lift heavy components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The lifting mechanism incorporates a self-locking feature that automatically maintains the top part at the desired height without requiring continuous manual intervention. The system serves itself by automatically locking into position, eliminating the need for users to constantly adjust or hold the position manually.

Inventive Principle:
Principle #25Self-service

2Area of stationary object

If the lifting mechanism is directly hinged to the bottom part and top part, then the structure can be compact, but the top part must horizontally move a long distance during lifting requiring large operating space

Engineering Contradiction:
Improveoperating spaceVSAvoidhorizontal movement distance
Core Design Contradiction:
Area of stationary objectVSLength of moving object

Solution Approach 1:

The patent introduces an intermediate linkage mechanism that changes the lifting motion from direct vertical movement to a combination of vertical and rotational movements through multiple dimensions. The linkage system allows the top part to be lifted by rotating the lifting arm, which converts the motion path into a more compact trajectory that reduces horizontal displacement while maintaining lifting functionality.

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

3Manufacturing precision

If position holes and position bolts are used for height adjustment, then the top part can be positioned at fixed heights, but the structure becomes complex and lifting height is limited

Engineering Contradiction:
Improvepositioning precisionVSAvoidstructure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces the static positioning system with fixed holes and bolts with a dynamic lifting mechanism driven by an electric motor. The motorized system allows continuous height adjustment without being constrained to fixed positions, eliminating the need for multiple position holes and bolts. This dynamic approach maintains positioning precision while reducing structural complexity and expanding the range of adjustable heights.

Inventive Principle:
Principle #15Dynamics
