Wrapping Machine Light Projection for Flexible Zone Marking

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wrapping machines require manual painting or taping of wrapping zones on the floor, which fades or peels over time, limiting their flexibility and usability across different locations.

Innovation Solution

A wrapping machine equipped with an indicating device that projects a visible wrapping-zone indicator using light sources to define the wrapping zone, eliminating the need for physical markings on the floor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If paint or tape is used to mark the wrapping zone on the floor, then the wrapping zone boundary is clearly indicated, but the markings fade or peel over time requiring maintenance and reapplication

Engineering Contradiction:

Improvewrapping zone indication durabilityVSAvoidmaintenance effort

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the mechanical marking system (paint or tape applied to the floor) with an optical indication system. The wrapping machine includes an indicating device with light sources that project visible wrapping-zone indicators directly onto the floor, eliminating the need for physical markings and their associated maintenance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wrapping machine itself provides the indication function through its indicating device, rather than relying on separate floor markings. The machine projects the wrapping zone boundary automatically when in operation, making the system self-sufficient and eliminating the need for external maintenance of markings.

Inventive Principle:

Principle #25Self-service

2Reliability

If paint or tape is applied to mark the wrapping zone, then the wrapping zone is clearly defined, but the wrapping machine cannot be easily moved to different locations

Engineering Contradiction:

Improvewrapping zone indicationVSAvoidmachine mobility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

By replacing static floor markings with a dynamic optical projection system integrated into the wrapping machine, the patent enables the machine to indicate the wrapping zone at any location. The light sources project the wrapping-zone indicator directly onto the floor at the machine's current position, allowing free movement without requiring markings at each location.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transitions from a static indication system (fixed paint or tape markings) to a dynamic system where the wrapping zone indicator moves with the wrapping machine. The indicating device projects the wrapping zone boundary relative to the machine's position, enabling adaptability to different locations while maintaining clear zone definition.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If paint or tape is used to indicate the wrapping zone, then the zone boundary is visible, but the markings deteriorate due to fading, chipping, or peeling

Engineering Contradiction:

Improvewrapping zone visibilityVSAvoidmarking longevity

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The patent substitutes the mechanical marking materials (paint and tape) with an optical indication system using light sources. The projected wrapping-zone indicator remains visible and does not deteriorate like physical markings, as it is generated electronically and projected onto the floor surface without physical contact or adhesion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of using durable but maintenance-intensive paint or tape, the patent employs a disposable-like optical projection that can be activated and deactivated as needed. The light-based indicator provides temporary but perfect visibility for each wrapping operation without the degradation issues of physical markings.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
