Solution Overview

Problem

Existing rowing machine handles are rigid and inflexible, preventing natural wrist rotation and causing discomfort, and alternative designs often require complex components that can fail or lead to improper technique, risking injury and disrupting the natural rowing motion.

Innovation Solution

A strap clip that secures straps to the rowing machine handle, allowing for a comfortable, alterable grip without interfering with the handle's operation, enabling smooth transitions between handle and strap use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rigid handle is used, then the handle structure is simple and strong, but the operator cannot adjust body position and natural wrist rotation is prevented

Engineering Contradiction:

Improvehandle adaptabilityVSAvoidoperator comfort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The handle is divided into multiple segments that can rotate relative to each other about a central axis. Each segment can be independently positioned to accommodate different operator preferences and body types, allowing adjustment of hand and wrist positions while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle incorporates dynamic rotation capabilities, allowing the segments to move from fixed positions to alternative orientations during operation. This enables the operator to adjust body position and wrist rotation naturally while maintaining a secure grip throughout the rowing motion.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a pivotable handle design is used, then handle orientation can be changed, but the pivot component may fail due to wear and manufacturing imperfections

Engineering Contradiction:

Improvehandle orientation adjustmentVSAvoidcomponent failure risk

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The design incorporates redundant support structures and load-distributing features that prevent excessive stress concentration on any single pivot component. By distributing forces across multiple contact points and structural elements, the system cushions against wear and manufacturing variations before they can lead to failure.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The handle segments utilize flexible materials and thin-walled structures that can accommodate minor manufacturing variations and wear without rigid failure. The flexibility allows for stress redistribution and prevents catastrophic failure while maintaining functional integrity.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If a complex handle system with multiple components is used, then natural wrist rotation and hand positioning are enabled, but component failure can render the entire system unusable

Engineering Contradiction:

Improvenatural wrist rotationVSAvoidsystem usability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The handle system is segmented into independent rotational sections that can function with partial component failure. If one segment or pivot fails, the remaining segments maintain operational capability, allowing the operator to continue using the handle with reduced but still effective functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle components are designed with uniform material properties and structural characteristics throughout, ensuring consistent performance and failure modes. This homogeneity allows for predictable behavior and easier replacement of any single component without affecting the overall system design philosophy.

Inventive Principle:

Principle #33Homogeneity

4Adaptability or versatility

If disconnected separate handles are used, then operator flexibility is increased, but improper technique may be formed

Engineering Contradiction:

Improveoperator flexibilityVSAvoidproper technique

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The handle design provides multiple functions within a single integrated structure. It maintains the connection between handle segments to ensure proper rowing technique while simultaneously offering rotational flexibility and adjustable positioning. The universal design accommodates different operator needs without compromising technical correctness.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A strap clip for a rowing machine is attachable to a handle of the rowing machine. The strap clip can secure attachment ends of straps to the handle. The strap clip can additionally hold interaction ends of the straps against the handle, such as when the straps are not in use. Due to the location where the straps are held against the handle by the strap clip, an operator can easily and effectively transition between using the handle and using the straps during operation of the rowing machine, both seamlessly and with stoppage of the operation of the rowing machine.
