Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing anchor elements that protrude from drilled holes in materials pose safety risks and obstacles when their required length is slightly longer than standard lengths, and custom-tailored lengths are costly.

Innovation Solution

Cutting the protruding portion of standard-length anchor elements to the required length and covering it with a protective cap, using an adhesive material to ensure safety and durability, while allowing for reliable anchoring and reduced production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a standard-length anchor element is used, then production cost is reduced, but the projecting portion becomes too long and represents a safety risk and/or obstacle

Engineering Contradiction:

Improveproduction costVSAvoidsafety risk

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The anchor element is divided into two parts: a standardized anchor portion that remains in the material and a separate protective cap that covers the projecting portion. This segmentation allows the anchor element to be manufactured in standard lengths while eliminating the safety risk of the projecting portion through the protective cap.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A protective cap is introduced as an intermediary component between the anchor element and the environment. This protective cap covers the projecting portion, eliminating the safety risk and obstacle problems while allowing the use of cost-effective standard-length anchor elements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a custom-tailored length anchor element is manufactured, then the projecting portion length is precisely matched to requirements, but production costs are high

Engineering Contradiction:

Improvelength precisionVSAvoidproduction cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The solution segments the anchor element into a standardized mass-produced anchor portion and a separate protective cap. This allows the anchor element to be manufactured in standard lengths at low cost, while the protective cap provides the necessary length customization and protection without increasing anchor element production costs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of changing the manufacturing parameters of the anchor element itself, the solution changes the state of the projecting portion by covering it with a protective cap. This parameter change approach maintains cost-effectiveness while achieving the desired length precision and safety.
