Solution Overview

Problem

Gym patrons face the risk of damaging their phones or cameras by placing them on the ground or unstable gym equipment during workouts, as current mounts require ground support or balance on other equipment.

Innovation Solution

A lifting rack j-hook phone/camera mount assembly that integrates a flexible arm and modified j-hook body to securely attach to the weightlifting rack, providing stable support and adjustable positioning for mobile devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If phone/camera is placed on the ground or other equipment, then it is easy to position, but the risk of damage increases and mounting becomes unsteady

Engineering Contradiction:
Improveease of positioningVSAvoidmounting stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines a phone/camera mount with a weightlifting rack structure, merging two previously separate functions (supporting equipment and holding devices) into a single integrated unit. The mount becomes part of the rack itself, eliminating the need to place devices on the ground or other equipment while ensuring stable mounting through the rack's sturdy construction.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If current phone/camera mounts are used on ground or equipment, then they provide basic support, but they increase risk of damage and create unsteady mounting

Engineering Contradiction:
Improvesupport capabilityVSAvoiddamage risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a dedicated mounting structure as an intermediary between the weightlifting rack and the phone/camera. This intermediary mount provides a stable, purpose-built platform that transfers the load to the rack's strong structure, eliminating the harmful effect of placing devices directly on the ground or unstable surfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a dedicated mount structure is created, then damage risk is reduced and stability is improved, but device complexity increases

Engineering Contradiction:
Improvemounting securityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs the mount to serve multiple functions: it attaches to the weightlifting rack, holds the phone/camera securely, and provides adjustable positioning. By making the mount universal and multi-functional, the design achieves high reliability without excessive complexity, as a single structure accomplishes multiple tasks that would otherwise require separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
