Solution Overview

Problem

Conventional rowing machines occupy significant floor space when not in use, making them less space-efficient for home storage.

Innovation Solution

A rowing machine design featuring a frame with a hinge joint that allows the beam to pivot and fold, reducing the overall footprint by aligning or tilting sections when transitioning from an operational to a storage position, utilizing a pull mechanism with a resistance system and a dampener to facilitate compact storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the rowing machine uses a fixed beam structure, then the structural stability is maintained, but the floor space occupied during storage is large

Engineering Contradiction:
Improvefloor space occupiedVSAvoidstructural stability
Core Design Contradiction:
Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The beam is divided into multiple sections (first beam section, second beam section, third beam section) connected by hinge joints, allowing the structure to be segmented for folding while maintaining stability when assembled

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The beam structure transitions from a static fixed configuration to a dynamic foldable configuration through hinge joints, enabling the rowing machine to adapt between operational and storage states

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the rowing machine beam is made foldable with hinge joints, then the storage space is reduced, but the structural complexity increases

Engineering Contradiction:
Improvestorage footprintVSAvoidbeam structure complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The beam is segmented into multiple sections connected by hinge joints, allowing compact folding while distributing the complexity across standardized joint components rather than a single complex mechanism

Inventive Principle:

AI summary

A rowing machine includes a frame where the frame includes a first support, a second support, and a beam extending between the first support and the second support. A track is defined by at least a portion of the beam, and a sliding member is movably disposed on the track. A hinge joint is disposed in the beam between the first support and the second support defining a first section of the beam and a second section of the beam.
