Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If exercise devices use fixed configuration for the whole exercise, then device structure is simple and stable, but inability to generate unpredictable motor interferences limits proprioceptive training effectiveness

Engineering Contradiction:

Improveability to generate unpredictable motor interferencesVSAvoiddevice structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The exercise device transforms from a static fixed configuration to a dynamic system where the mass can be positioned at different locations on the suspension means, allowing unpredictable movements and motor interferences during exercise, thereby improving proprioceptive training effectiveness without requiring complex active control mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device serves multiple functions: it can be used for various exercises (arm muscles, core stability, balance training), accommodates different user skill levels by adjusting mass position, and generates both predictable and unpredictable motor interferences, making it universally applicable across different training disciplines

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If exercise device generates unpredictable motor interferences, then proprioceptive training effectiveness is improved, but device becomes more complex and expensive to produce

Engineering Contradiction:

Improveproprioceptive training effectivenessVSAvoidproduction cost and complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The device uses simple, inexpensive components: a basic suspension means (rope, band, or spring) and a detachable mass that can be made from simple materials. This avoids expensive sensors, motors, or electronic control systems while still achieving reliable proprioceptive training through passive mechanical unpredictability

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The device generates motor interferences passively through the natural dynamics of the suspended mass and suspension means interaction, without requiring external power sources, sensors, or active control systems. The unpredictability arises automatically from the physical system's inherent dynamics

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If exercise device uses detachable mass with suspension means, then versatility and ease of assembly are improved, but connection reliability between components may be compromised

Engineering Contradiction:

Improveease of assembly and configurationVSAvoidconnection reliability between components

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The device is divided into separate modular components (suspension means, mass, fastening element) that can be independently assembled and configured. The fastening element provides a reliable connection interface between the mass and suspension means, allowing easy assembly while maintaining connection reliability through dedicated coupling mechanisms

Inventive Principle:

Principle #1Segmentation
