Solution Overview

Problem

The heavy weight of laser system modules makes them difficult to install and remove safely without mechanical assistance, requiring multiple personnel or inefficient resource use, especially when servicing field locations with varying module heights.

Innovation Solution

A modular service shelf that can be attached at different heights within the laser system, allowing modules to be slid onto it for safe handling and storage, enabling a single technician to service modules efficiently by distributing the weight and allowing internal storage within the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple personnel are used to service heavy laser modules, then safety and correctness of module handling is improved, but resource efficiency and cost increase due to requiring several technicians

Engineering Contradiction:
Improvesafety of module handlingVSAvoidresource efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

A mechanical assistance device is introduced as an intermediary between the technician and the heavy laser module. The device includes a support structure with adjustable height and a lifting mechanism that enables a single technician to safely handle modules weighing over 100lbs, eliminating the need for multiple personnel while maintaining safety standards

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If adjustable lifting mechanisms or tables are used to service modules at different heights, then ease of servicing is improved, but device complexity and resource requirements increase

Engineering Contradiction:
Improveease of servicing modulesVSAvoidcomplexity of lifting mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure incorporates an adjustable height mechanism that can be dynamically repositioned to match the location of laser modules within the rack system. This dynamic adjustment capability allows the same simple device to service modules at any height without requiring complex specialized equipment for each height level

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lifting device is designed as a universal tool that can service laser modules at any height within the rack system. The adjustable support structure and standardized lifting mechanism allow a single device to perform multiple functions across different module locations, eliminating the need for height-specific equipment

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

3Productivity

If heavy laser modules are installed high in the rack system, then space utilization is improved, but difficulty of installation and removal increases due to height and weight

Engineering Contradiction:
Improvespace utilizationVSAvoidease of installation and removal
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The mechanical assistance device serves as an intermediary that bridges the gap between the technician and high-mounted heavy modules. The device's support structure can be positioned at elevated rack levels, and the lifting mechanism provides the necessary mechanical advantage to install and remove modules from high locations without straining the technician

Inventive Principle:
Principle #24Intermediary (Mediator)
