Solution Overview

Problem

Existing lifting technologies for large wall and panel structures in construction are unsafe, inefficient, and require multiple workers, lacking adequate mechanisms for secure hoisting and stabilization in a vertical position.

Innovation Solution

An electronic winch system with telescoping components and keepers is used to lift and stabilize wall structures, allowing single-operator operation, safe hoisting, and secure vertical placement, with adjustable configurations for various panel sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual lifting techniques are used with multiple workers, then wall structures can be lifted into place, but worker safety is compromised due to injuries from slippage and mishaps

Engineering Contradiction:

Improveworker safetyVSAvoidlifting operation safety

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical lifting with an electronic winch system that uses motorized mechanical advantage. The winch device with cable and reel mechanism substitutes human physical effort, eliminating worker exposure to lifting hazards while maintaining controlled, safe operation for hoisting wall panels to vertical position.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces keepers as intermediary safety devices that catch and secure wall panels during the hoisting process. These keepers act as mediators between the winch system and the wall panel, providing an additional safety layer that prevents accidental drops and ensures controlled placement, directly addressing worker safety concerns.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If multiple workers are used for lifting, then wall structures can be safely hoisted, but labor costs and operational complexity increase

Engineering Contradiction:

Improvelifting safetyVSAvoidoperational efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements a self-service hoisting system where the electronic winch automatically performs the lifting function that previously required multiple workers. The system is designed to be operated by a single technician who controls the winch, eliminating the need for additional labor while maintaining safe and reliable wall panel hoisting operations.

Inventive Principle:

Principle #25Self-service

3Force

If industrial lifting devices are used, then lifting capacity is sufficient, but the devices are ill-equipped for safe and secure lifting of large wall structures

Engineering Contradiction:

Improvelifting capacityVSAvoidsecure hoisting capability

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

The patent applies local quality by designing the winch system with specific features tailored for wall panel hoisting: the cable is routed to attach at optimal points on the wall structure, the keepers are positioned to catch panels at critical angles, and the electronic control system is calibrated for the specific weight and dimensions of wall panels, ensuring secure and reliable lifting.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent incorporates dynamic elements including the ability to adjust the winch position and cable attachment points, movable keepers that can be repositioned along the hoist path, and electronic control that can modulate lifting speed and force. This dynamic capability allows the system to adapt to different wall panel sizes and lifting conditions, enhancing secure hoisting capability.

Inventive Principle:

Principle #15Dynamics

4Volume of moving object

If telescoping components are used for portability, then device size is minimized for transport, but structural stability during operation must be maintained

Engineering Contradiction:

Improvetransport sizeVSAvoidstructural stability

Core Design Contradiction:

Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The patent uses nesting by placing telescoping structural members inside one another for compact storage and transport. During operation, these nested members extend to their full length and are locked into position, providing the necessary structural stability for safe wall panel hoisting while maintaining portability when collapsed.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

System, apparatus, device, kit, method and associated technique for safely and securely lifting wall and other structures to a vertical position. An electronic winch device that when connected to an end of a wall structure lifts the structure. A keeper or catchment such that when the electronic winch has hoisted the wall structure to a substantially vertical position, catches and keeps the wall structure in place, allowing the technician to more properly secure the wall structure. The apparatuses are also designed for portability and collapsibility, with structural members telescoping inside one another to minimize size in transport but securely configurable when extended and locked into place.
