Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the load carrier is suspended from multiple positioning cables connected directly to the load carrier, then the positioning cable tension can be controlled, but the working space is limited and the load carrier cannot be effectively controlled in peripheral regions

Engineering Contradiction:
Improveworking spaceVSAvoidload carrier control
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The cable connectors are made pivotable about two orthogonal pivot axes, transforming the rigid cable connection into a dynamic, adaptable connection. This allows the cable connectors to automatically adjust their orientation based on the load carrier's position, enabling effective control in peripheral regions while expanding the working space.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By introducing pivotable cable connectors with two degrees of freedom (two orthogonal pivot axes), the system adds rotational dimensions to the cable-load carrier connection. This dimensional enhancement allows the load carrier to be positioned and controlled in three-dimensional space, including peripheral regions that were previously inaccessible.

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

2Area of stationary object

If the load carrier operates in peripheral regions close to suspension devices, then more working space is utilized, but sagging occurs in positioning cables and control becomes difficult

Engineering Contradiction:
Improveworking spaceVSAvoidpositioning cable stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The pivotable cable connectors dynamically adjust the cable orientation in response to position changes, allowing the system to maintain stability even when operating in peripheral regions where sagging would normally occur. The connectors adapt to the changing geometry, preventing cable instability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the orientation parameter of the cable connectors through pivoting about two orthogonal axes. This parameter adjustment allows the cables to maintain optimal tension and alignment even when the load carrier is positioned in peripheral regions, preventing sagging and maintaining stability.

Inventive Principle:
Principle #35Parameter changes

3Area of stationary object

If traditional single-cable suspension is used, then the system structure is simple, but the load carrier cannot be effectively controlled in peripheral regions and working space is limited

Engineering Contradiction:
Improveworking spaceVSAvoidsuspension system structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The pivotable cable connectors introduce controlled complexity by adding two degrees of freedom to each cable connection. This dynamic capability enables the load carrier to be precisely positioned in peripheral regions and expands the working space, justifying the increased structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By adding pivotable connections with two orthogonal axes, the system transitions from simple linear cable tensioning to multi-dimensional positioning control. This dimensional enhancement enables operation in peripheral regions and significantly expands the effective working space.

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