Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If permanently mounted crossbars are used at regular intervals, then the structural simplicity and ease of manufacture are improved, but the adaptability to different user heights is worsened

Engineering Contradiction:

Improveease of manufactureVSAvoidadaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The crossbar system is segmented into removable crossbars and stationary crossbars, allowing the removable crossbars to be repositioned to different heights to accommodate different user shoulder heights while maintaining the structural integrity of the stationary crossbars

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The crossbar system transitions from a static configuration with fixed crossbars to a dynamic configuration where removable crossbars can be moved between different height positions, enabling adaptation to different users while maintaining structural simplicity

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If removable crossbar assembly is added to provide height adjustment, then the adaptability to different user heights is improved, but the device complexity and structural stability are worsened

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment mechanism is segmented into separate components including the removable crossbar, brackets that attach to stationary crossbars, and securement flaps with notches, allowing each component to perform a specific function while maintaining overall system simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Brackets serve as intermediary components that connect the removable crossbar to the stationary crossbar structure, providing a simple mechanical interface that enables height adjustment without requiring complex attachment mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If removable crossbar assembly is added to enable height adjustment, then the adaptability to different user heights is improved, but the structural stability during exercise is worsened

Engineering Contradiction:

ImproveadaptabilityVSAvoidstability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The securement flaps are pre-positioned in the open state during assembly, and the user performs the preliminary action of pivoting them upward to engage the notches with the stationary crossbar, ensuring stable attachment before exercise begins

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notches in the securement flaps are shaped to receive and engage the rounded stationary crossbars, creating a secure mechanical interlock that prevents movement during exercise while allowing for easy release when needed

Inventive Principle:

Principle #14Spheroidality (Curvature)
