Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the body type is changed according to the vehicle's intended use, then the usability of the vehicle is increased, but the complexity of the vehicle structure increases

Engineering Contradiction:

ImproveusabilityVSAvoidvehicle structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vehicle body is divided into a fixed part (frame) and a variable part that can be selectively attached and detached. This segmentation allows the vehicle structure to be simplified while maintaining the capability for body type changes, resolving the contradiction between adaptability and structural complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vehicle body configuration is made dynamic through the use of magnetically controlled engagement mechanisms that allow the variable part to be easily attached and detached. This dynamic design enables quick reconfiguration without complex mechanical operations, maintaining simplicity while achieving adaptability.

Inventive Principle:

Principle #15Dynamics

2Productivity

If a magnetic controller is used to form an engaging magnetic field, then the connection and separation speed is increased, but the energy consumption increases

Engineering Contradiction:

Improveconnection and separation speedVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The magnetic controller operates periodically by selectively supplying control magnetic fields only when connection or separation is required, rather than maintaining continuous magnetic fields. This periodic operation achieves rapid connection and separation while significantly reducing overall energy consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Traditional mechanical connection and separation mechanisms are replaced with a magnetic field-based system. The magnetic controller generates engaging magnetic fields to automatically attract and connect parts, eliminating the need for manual mechanical operations and thereby increasing productivity while managing energy consumption through controlled field generation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a lifter is used to separate or set the variable part, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveconnection and separation operationVSAvoidapparatus configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The lifter is designed to automatically separate or set the variable part through magnetic attraction and gravitational force without requiring complex control mechanisms. The system serves itself by using the magnetic field to initiate movement and gravity to complete the separation or positioning, improving ease of operation while minimizing additional complexity.

Inventive Principle:

Principle #25Self-service
