Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing recognition methods for employees, such as stickers and metal awards, are not durable, safe, or easily updatable for hardhats and protective helmets, and do not provide a professional or lasting way to acknowledge performance and service, while also posing electrical hazards.

Innovation Solution

A detachable, non-conductive holder for attaching recognition awards or personnel identification units, such as RFID chips, to hardhats and helmets, allowing for customization and easy replacement, using a pocket or accessory slot, and incorporating a clear plastic lens for protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If stickers are used for recognition, then cost is reduced, but durability and professional appearance deteriorate

Engineering Contradiction:

ImprovecostVSAvoiddurability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent uses inexpensive plastic or acrylic materials for the recognition award instead of expensive metal, accepting that it may be replaced over time. This resolves the contradiction by using a cheap material that is sufficiently durable for the application while maintaining cost-effectiveness.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The recognition award combines plastic/acrylic material with metal fastening components (screws, clips) to create a composite structure. The plastic provides durability and professional appearance, while the metal components provide secure attachment, resolving the contradiction between cost and durability.

Inventive Principle:

Principle #40Composite materials

2Reliability

If metal awards are used for recognition, then professional appearance and durability are improved, but safety deteriorates due to electrical shock hazards

Engineering Contradiction:

ImprovedurabilityVSAvoidelectrical shock hazard

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from conductive metal to non-conductive plastic or acrylic. This parameter change eliminates the electrical shock hazard while maintaining the durability and professional appearance needed for recognition awards in construction environments.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses plastic materials that are non-conductive and sufficiently durable for the application. While plastic may be less durable than metal in some aspects, it provides the necessary safety特性 (non-conductive) while maintaining adequate durability for recognition purposes.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If stickers are used for recognition, then cost is reduced and ease of application is improved, but adaptability deteriorates as they cannot be removed or updated

Engineering Contradiction:

ImprovecostVSAvoidremovability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent separates the recognition award from the hard hat by using a removable attachment mechanism (screws, clips, or adhesive backing). This segmentation allows the recognition award to be independently removed, replaced, or updated without affecting the hard hat, resolving the contradiction between cost and adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a dynamic system where the recognition award can be easily attached and detached. The use of removable fastening mechanisms transforms the static sticker into a dynamic component that can be updated as needed, providing adaptability while maintaining cost-effectiveness.

Inventive Principle:

Principle #15Dynamics

4Strength

If metal pins are used for attachment, then strength is improved, but safety deteriorates due to electrical shock hazards

Engineering Contradiction:

Improveattachment strengthVSAvoidelectrical shock hazard

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the attachment mechanism from metal pins to non-conductive alternatives such as plastic screws, acrylic clips, or adhesive backings. This parameter change maintains attachment strength while eliminating the electrical shock hazard associated with metal components.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses non-metallic attachment components that are sufficiently strong for the application. While metal pins provide maximum strength, the non-conductive alternatives provide adequate attachment strength while ensuring safety in electrical environments.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
