Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the robot uses a fixed shelf unit for temporary storage, then the structure is simple, but the space usage is inefficient and travel distances increase

Engineering Contradiction:
Improvestorage capacityVSAvoidshelf unit structure
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The shelf unit incorporates a rotatable portion that can rotate relative to the support structure, transforming the static storage system into a dynamic one. This rotation capability allows the shelf to reorient and maximize storage space utilization, directly resolving the contradiction between simple structure and efficient space usage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotatable portion adds a rotational dimension to the otherwise fixed shelf structure. By introducing this additional degree of freedom, the system can access and utilize storage space more effectively without significantly complicating the overall structure, thereby increasing storage capacity while maintaining relative structural simplicity.

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

2Use of energy by moving object

If the robot travels longer distances to access storage locations, then the robot can use a simpler fixed shelf structure, but energy consumption increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidtravel time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The dynamic rotatable shelf unit allows the robot to optimize its travel path by rotating the shelf to position items in optimal locations. This reduces unnecessary travel distances and time, directly addressing the contradiction between energy consumption and travel time loss.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The robot can pre-rotate the shelf unit to position frequently accessed items in optimal locations before retrieval operations begin. This preliminary action minimizes subsequent travel time and energy consumption during item retrieval, resolving the contradiction between energy use and time loss.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the pick up device has limited movement range, then the device complexity is reduced, but the ability to reach different storage locations is compromised

Engineering Contradiction:
Improvereach capabilityVSAvoidpick up device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pick up device incorporates rotation capability around a vertical axis in addition to linear movement, creating a dynamic positioning system. This allows the device to reach multiple storage locations without requiring excessive linear travel range, balancing adaptability with controlled device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By adding rotational movement around a vertical axis to the linear movement capability, the pick up device gains access to a three-dimensional workspace. This dimensional expansion allows the device to reach different storage locations more effectively without proportionally increasing the device's structural complexity.

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