Solution Overview

Problem

Variable concrete segment thicknesses and coverings over reinforcement make it difficult to position and attach installation parts securely on concrete surfaces without complex fastening methods, especially when formwork elements are absent.

Innovation Solution

An installation part with a tubular side wall and fastening elements that can be easily attached to reinforcement, featuring adjustable positions and a connecting structure for secure fastening, allowing for simplified positioning and easy access after concrete setting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional installation parts are positioned and fastened without formwork elements, then the installation can be performed on open concrete surfaces, but the positioning and fastening become complex and difficult to secure tightly

Engineering Contradiction:

Improveadaptability to concrete surfaces without formworkVSAvoidcomplexity of positioning and fastening

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The installation part is divided into separate components: a fastening element with gripping structure and an installation body. This segmentation allows the fastening element to be specifically designed for secure attachment to reinforcement while the installation body provides the functional housing, simplifying both positioning and fastening operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fastening element acts as an intermediary component between the installation body and the reinforcement. It provides a specialized gripping structure that securely attaches to the reinforcement, thereby simplifying the overall fastening process and enabling reliable installation on open concrete surfaces without formwork elements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If variable concrete coverings over reinforcement are used, then flexibility in concrete segment design is improved, but positioning the installation parts relative to the intended concrete segment surface becomes difficult

Engineering Contradiction:

Improveflexibility in concrete segment designVSAvoidpositioning precision relative to concrete segment surface

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The fastening element is designed with adjustable positioning capabilities, allowing it to be secured at different locations along the reinforcement. This dynamic adjustment feature enables precise positioning of the installation body relative to the intended concrete segment surface, accommodating variable concrete coverings while maintaining manufacturing precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The installation part allows for parameter changes in positioning by enabling the fastening element to be attached at various distances from the ends of the installation body. This flexibility in positioning parameters ensures accurate placement relative to the concrete segment surface despite variable concrete coverings over the reinforcement.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If multiple fastening positions are provided on the installation body, then adaptability to different reinforcement positions is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to different reinforcement positionsVSAvoidcomplexity of fastening element structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening element is designed as a separate, modular component with an integrated gripping structure. This segmentation allows multiple fastening positions to be achieved through simple attachment variations rather than complex internal mechanisms, maintaining structural simplicity while providing adaptability to different reinforcement positions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fastening element incorporates a self-gripping structure that automatically secures to the reinforcement without requiring additional fastening components or complex assembly procedures. This self-service mechanism provides multiple fastening positions through simple placement variations, avoiding increased device complexity.

Inventive Principle:

Principle #25Self-service
