Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional training bench is used for weight training, then strength training function is provided, but the equipment is bulky and heavy making it difficult to transport

Engineering Contradiction:

Improvestrength training functionVSAvoidequipment weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The exercise apparatus is divided into a first main body and a second main body that can be folded relative to each other. This segmentation allows the equipment to be disassembled into smaller, more manageable sections for easy transport while maintaining full functionality when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The apparatus incorporates foldable main bodies that can transition between expanded and folded states. This dynamic structure enables the equipment to adapt between a large operational configuration for exercise and a compact configuration for storage and transport.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If conventional rowing machine is used for full-body exercise, then exercise function is provided, but the equipment is large in size

Engineering Contradiction:

Improvefull-body exercise functionVSAvoidequipment size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The rowing machine components are integrated into a segmented structure with first and second main bodies that can be folded. This allows the full-body exercise equipment to be divided into compact sections while maintaining all exercise functions when expanded.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The apparatus is designed so that when folded, the main bodies and components nest together to form a compact box shape, maximizing space efficiency and minimizing the volume occupied during storage and transport.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Volume of moving object

If conventional rowing machine is folded for space reduction, then size is reduced, but it lacks accessories for comprehensive strength training

Engineering Contradiction:

Improveequipment sizeVSAvoidtraining function

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The apparatus is designed as a multi-functional system that combines rowing machine capabilities with weight training accessories. The resistance units with resistance sources and pulling members enable both rowing exercises and strength training exercises for all four limbs, providing universal fitness functionality in a single compact device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If fitness equipment is made compact for easy storage, then portability is improved, but the equipment lacks comprehensive training accessories

Engineering Contradiction:

ImproveportabilityVSAvoidtraining accessory functionality

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The apparatus merges multiple training functions into a single integrated system. The resistance units with resistance sources are integrated into the compact structure, combining rowing machine functionality with weight training capabilities in one portable device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The compact apparatus provides universal fitness functionality through resistance units that can perform both rowing exercises and strength training for all four limbs, ensuring comprehensive training capability despite the compact size.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A portable exercise apparatus includes a first main body, a second main body, a seat, a pedal and at least two resistance units. The second main body is connected to the first main body, the first main body and the second main body are foldable relative to each other so as to be in a folded mode or an expanded mode. The seat can be slidably disposed on the first main body when the first main body and the second main body are in the expanded mode and the pedal is in a slanted position. Each of the two resistance units has a resistance source that can provide a resistance force. When the first main body and the second main body are in the folded mode, the resistance sources of the two resistance units are respectively arranged in the two receiving spaces.
