Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If coupling sections are integrated into the channel module, then structural stability is significantly improved, but device complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The coupling sections are integrated directly into the channel module, merging the coupling function with the channel structure. This eliminates the need for separate coupling mechanisms and significantly improves structural stability while the modular design keeps the added complexity manageable.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling sections serve multiple functions: they provide structural stability for the channel module, enable connection to underlying building blocks via coupling holes, and allow attachment of additional blocks via coupling studs. This multi-functionality resolves the contradiction by achieving high stability without proportionally increasing complexity.

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

2Stability of the object's composition

If coupling holes are provided laterally offset from the marble run, then hold on underlying building block is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvehold on underlying building blockVSAvoidmanufacturing precision
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The coupling holes are positioned at specific lateral offsets from the marble run at the coupling sections, creating localized connection points that optimize the hold on underlying building blocks. This localized positioning approach improves stability without requiring high precision across the entire channel module.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The channel module is segmented into distinct coupling sections at the ends and a central section in between. The coupling holes are concentrated in the coupling sections, allowing precision to be focused on specific areas rather than the entire structure, thereby reducing overall manufacturing precision requirements.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If coupling sections have lower height, then several chute building blocks can be connected without vertical protrusion, but coupling strength is reduced

Engineering Contradiction:
Improvecompact constructionVSAvoidcoupling strength
Core Design Contradiction:
Stability of the object's compositionVSStrength

Solution Approach 1:

Instead of increasing coupling strength through greater vertical height, the design uses lateral offset coupling sections that extend beyond the sides of the channel. This shifts the coupling mechanism to a different spatial dimension, allowing multiple blocks to connect compactly vertically while maintaining coupling strength through lateral distribution.

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

Solution Approach 2:

The coupling sections are positioned at the ends of the channel module in advance, with coupling holes and studs pre-configured for connection. This preliminary positioning allows several chute building blocks to be connected without vertical protrusion while ensuring adequate coupling strength through proper placement before assembly.

Inventive Principle:
Principle #10Preliminary action
