Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a clamping mechanism with screws is used to attach the accessory coupling device to the bicycle saddle, then the attachment reliability is improved, but the ease of operation deteriorates due to the need for screwdrivers and regular tightening

Engineering Contradiction:

Improveattachment reliabilityVSAvoidease of attachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the screw-based mechanical fastening system with a magnetic coupling system. The coupling module contains a magnet that magnetically attracts to a ferromagnetic component on the accessory, enabling tool-free attachment and detachment while maintaining secure connection. This substitution eliminates the need for screwdrivers and manual tightening operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the attachment mechanism from friction-based screw clamping to magnetic field-based attraction. By utilizing magnetic force as the attachment parameter, the system achieves both strong holding force and easy separation by simply overcoming the magnetic attraction, without requiring mechanical tools or adjustment operations.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a screw-based clamping mechanism is used, then the firmness of attachment is improved, but the time required for attachment increases due to tool usage and tightening procedures

Engineering Contradiction:

Improvefirmness of attachmentVSAvoidattachment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The magnetic coupling system replaces the multi-step screw fastening process with a single magnetic attraction action. The magnet in the coupling module automatically secures the accessory when brought near, eliminating the time required for screw insertion, tightening, and verification, while maintaining firm attachment through magnetic force.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic coupling mechanism is self-securing - when the accessory is brought near the coupling module, the magnetic force automatically engages and holds the components together without requiring external tools or manual tightening operations, significantly reducing attachment time.

Inventive Principle:

Principle #25Self-service

3Reliability

If a tool-based fastening system is used, then the security of attachment is improved, but the complexity of the device increases due to additional components and tools

Engineering Contradiction:

Improvesecurity of attachmentVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the complex screw-based mechanical fastening system with a simple magnetic coupling system. The coupling module contains a magnet that provides secure attachment through magnetic attraction, eliminating the need for screws, screwdrivers, and associated fastening components, thereby reducing overall device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts and eliminates the unnecessary screw fastening components from the attachment system. By removing screws, screwdrivers, and related mechanical fastening elements, the design achieves secure attachment with a simplified magnetic coupling mechanism, reducing the number of parts and overall system complexity.
