Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If programmable toys with microprocessor control are used, then functional versatility is improved, but device complexity and programming difficulty increase

Engineering Contradiction:
Improvefunctional versatilityVSAvoidprogramming complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides control functionality into separate control building elements that can be independently connected to function building elements. Each control element handles specific control signals, breaking down the complex programming task into simple physical connections. Children can create different functionalities by simply connecting and disconnecting control elements rather than writing programs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Control building elements act as intermediaries between the user and function building elements. Instead of directly programming microprocessors, users interact with simplified control elements that translate physical connections into control signals. This intermediary layer abstracts away the complexity of programming while maintaining functional versatility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If separate wiring is required for each function building element, then control precision is improved, but device complexity and ease of operation worsen

Engineering Contradiction:
Improvecontrol precisionVSAvoidwiring complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple control signals are merged into a single connector interface. The control building elements and function building elements use standardized connectors that combine multiple electrical contacts (power, ground, control signals) into one physical connection point. This allows precise control of multiple functions through a single unified connection rather than separate wiring for each function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector design provides universal interfaces that can simultaneously handle power supply, ground connections, and multiple control signals. A single connector type works across all building elements, enabling one connection to establish multiple electrical pathways for precise control without requiring separate dedicated wires for each function.

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

3Ease of operation

If manual activation of triggers is used, then ease of operation is improved, but adaptability and play value worsen

Engineering Contradiction:
Improveactivation simplicityVSAvoidplay value
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The control system transitions from static manual triggers to dynamic control signals that can be automatically generated and propagated. Control building elements can respond to various stimuli (physical interaction, sensors, timing) and dynamically activate multiple function elements in sequences or simultaneously, creating more varied and engaging play scenarios while maintaining simple physical interaction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where control signals can be triggered by user interaction and then propagate through connected function elements, creating observable effects that feed back into the play experience. This allows simple manual activation to result in complex, multi-functional responses that enhance play value without increasing operational complexity.

Inventive Principle:
Principle #23Feedback
