Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the rated resistance value is fixed, then the device structure is simple, but the adaptability for different training intensities deteriorates

Engineering Contradiction:

Improveadaptability for different training intensitiesVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gripper ring body is designed with non-uniform cross-sectional areas at different positions, creating local variations in elastic properties. Specifically, the cross-sectional area at the first position differs from that at the second position, causing different resistance characteristics when gripping at each position. This allows a single device to provide multiple resistance levels without additional components.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the physical parameter of the ring body by varying the cross-sectional area at different positions. This geometric parameter modification directly alters the elastic properties and resistance characteristics of each gripping position, enabling adjustable training intensity through position selection rather than structural complexity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the rated resistance value is adjusted by replacement or reconfiguration, then the adaptability improves, but the ease of operation deteriorates

Engineering Contradiction:

Improveadjustable training intensityVSAvoidease of adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Different positions on the gripper ring body are designed with distinct cross-sectional areas, creating localized differences in elastic resistance. Users can easily switch between training intensities by simply changing which position they grip, without any replacement or reconfiguration actions required.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device provides self-adjusting functionality through its geometric design. The varying cross-sectional areas inherently provide different resistance levels, and the user self-selects the appropriate resistance by choosing which position to grip, eliminating the need for external adjustment mechanisms.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the elastic properties are made uniform throughout, then the manufacturing precision is easier to achieve, but the functionality deteriorates

Engineering Contradiction:

Improvemulti-resistance training functionalityVSAvoidmanufacturing precision

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The ring body is manufactured with intentionally non-uniform cross-sectional areas at different positions. This local variation in geometry creates the desired multi-resistance functionality while remaining compatible with standard manufacturing processes like injection molding or 3D printing, which can easily accommodate varying cross-sections.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The gripper ring employs asymmetric cross-sectional design where the cross-sectional area at the first position is deliberately made different from that at the second position. This asymmetric geometry is straightforward to manufacture and directly produces the different elastic properties needed for multi-resistance training.

Inventive Principle:

Principle #4Asymmetry
