Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beginners learn swimming strokes directly in water, then they can practice real swimming movements, but they experience fear of water and poor learning effect due to incorrect techniques

Engineering Contradiction:

Improvelearning effectVSAvoidfear of water

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a training device as an intermediary between the learner and water environment. The device includes a support structure with guide rails that constrain and guide the learner's limbs through correct swimming stroke trajectories, providing a safe intermediate training environment before water entry

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device enables preliminary practice of swimming strokes on land before actual water entry. The guide rails pre-establish the correct movement paths for arms and legs, allowing learners to master proper techniques in advance without facing water-related fears

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If learners practice swimming strokes on land without proper guidance, then they can avoid water fear, but they develop wrong strokes resulting in poor learning effect

Engineering Contradiction:

Improvewater safetyVSAvoidstroke technique accuracy

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The device applies localized guidance through guide rails at specific positions for arm and leg movements. Each guide rail is positioned to enforce correct trajectory for specific body parts, ensuring locally accurate stroke mechanics while maintaining overall safety

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The guide rails act as mechanical intermediaries that physically guide the learner's limbs through correct stroke paths, providing tactile feedback and constraint that ensures proper technique development without water exposure

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a swimming exercise device is designed with multiple stroke simulation capabilities, then it provides versatility for learning different strokes, but the device complexity increases

Engineering Contradiction:

Improvestroke simulation varietyVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device employs universal guide rail structures that can accommodate different swimming stroke patterns. The support structure and guide rail system are designed to be adjustable and adaptable to various stroke types (freestyle, breaststroke, backstroke) without requiring completely separate mechanisms for each stroke

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device divides the complex task of teaching multiple strokes into separate, manageable guide rail modules. Each stroke type has its own dedicated guide rail configuration, allowing the complex functionality to be segmented into simpler, interchangeable components

Inventive Principle:

Principle #1Segmentation
