Solution Overview

Problem

Existing recumbent exercising devices are limited to a single training mode for stretching legs and require multiple apparatuses for various training modes, leading to waste and space inefficiency.

Innovation Solution

A multifunctional recumbent exercising device with a base frame, transmission units, retracting units, resistance units, guiding pieces, and movable seats that allow for various training modes by changing the relative position between the movable seat and the guiding piece.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single training mode device is used, then the device structure is simple, but the training diversity is limited and multiple apparatuses are needed for various training modes

Engineering Contradiction:

Improvetraining mode diversityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The movable seat is designed to be repositionable along the guiding piece to different locations (first location for rowing, second location for stretching, third location for lifting), allowing a single device to perform multiple training functions. This multi-functionality resolves the contradiction by enabling one device to replace multiple specialized apparatuses.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The seat is made dynamically repositionable rather than fixed, allowing users to adjust its position along the guiding piece according to different training needs. This dynamic adjustment capability enables the device to adapt between different training modes without requiring multiple separate apparatuses.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple exercising apparatuses are purchased for various training modes, then the training diversity is enhanced, but the space occupation and cost increase

Engineering Contradiction:

Improvetraining mode diversityVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines rowing, stretching, and lifting training functions into a single integrated device. By merging multiple training modes that would traditionally require separate apparatuses into one unified system, the device reduces space occupation while maintaining training diversity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single device is designed to universally support multiple training modes through the repositionable seat mechanism, eliminating the need for multiple separate apparatuses and thereby reducing the total space required for exercise equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the rack unit structure is changed between horizontal and upright states for different training modes, then various exercising types are achieved, but the operation complexity and assembly time increase

Engineering Contradiction:

Improveexercising typesVSAvoidoperation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of requiring structural reconfiguration between horizontal and upright states, the patent employs a dynamic seat positioning system that allows the seat to move along the guiding piece. This simpler dynamic adjustment replaces complex structural changes, improving ease of operation while maintaining versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The guiding piece is segmented with multiple positioning locations that allow the seat to be independently repositioned for different training modes. This segmentation enables mode switching without requiring overall structural reconfiguration, simplifying operation.

Inventive Principle:

Principle #1Segmentation

AI summary

A multifunctional recumbent exercising device is disclosed, including a base frame, a first transmission unit, a first retracting unit, a resistance unit, a first guiding piece and a first movable seat. By changing a relative position between the first movable seat and the first guiding piece, the position of a first slide-assistance portion of the first movable seat on the base frame can be changed. The multifunctional recumbent exercising device allows an operator to apply force to a first side or a second side of the base frame, in order to select various kinds of training modes.
