Solution Overview

Problem

Mounting large and heavy articles such as televisions, paintings, or mirrors often requires multiple people due to their uneven weight distribution, making it time-consuming and costly for delivery and mounting services.

Innovation Solution

A support tray system with a load lift frame that includes a support tray removably coupled to a load lift frame, equipped with wheels, a lifting mechanism, and extenders, allowing a single person to lift and align the article to a desired location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple people are used to mount heavy articles, then the article can be lifted and positioned, but the process becomes time-consuming and costly

Engineering Contradiction:

Improveease of mountingVSAvoidmounting time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The support tray acts as an intermediary device between the heavy article and the mounting location. It provides a stable platform with built-in lifting mechanisms that enable a single person to safely lift and position heavy articles that would otherwise require multiple people, thereby reducing mounting time and labor costs

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the manual mechanical system of multiple people physically lifting and carrying articles with a mechanical lifting system integrated into the support tray. This system uses mechanical advantage through levers, pulleys, or hydraulic mechanisms to amplify the force of a single person, enabling them to lift heavy loads efficiently

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If multiple people are used to mount heavy articles, then the article can be positioned accurately, but the cost and complexity increase

Engineering Contradiction:

Improvealignment precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The support tray incorporates leveling mechanisms and adjustable components that create an equipotential working surface, allowing the tray to be easily leveled and positioned at any height. This enables a single person to achieve precise alignment of heavy articles without requiring multiple people to manually adjust and balance the load

Inventive Principle:

Principle #12Equipotentiality

Solution Approach 2:

The support tray features dynamic adjustment capabilities including height adjustment, angle adjustment, and position adjustment mechanisms. These dynamic features allow the tray to be easily repositioned and aligned to various mounting locations, providing the precision of multiple people with the simplicity of a single-person operation

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If a support tray is used to lift heavy articles, then weight distribution is improved, but the device complexity increases

Engineering Contradiction:

Improveweight distributionVSAvoiddevice complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support tray divides the heavy article's weight into multiple contact points and distributes it across several structural elements of the tray. This segmentation of the load-bearing function allows the tray to handle heavy weights while maintaining a relatively simple overall structure that can be managed by a single person

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support tray concentrates structural reinforcement and weight-distribution features at specific critical locations rather than throughout the entire structure. This localized strengthening provides optimal weight distribution and stability while minimizing unnecessary material and structural complexity

Inventive Principle:

Principle #3Local quality
