Solution Overview

Problem

Existing installation parts for electrical and concrete installations face difficulties in completely breaking out wall areas delimited by predetermined breaking points due to insufficient force distribution, often resulting in incomplete removal or requiring additional manipulation, especially in confined spaces.

Innovation Solution

The engagement contour is reinforced with a cup-like pocket and additional material webs that extend over the wall area, allowing the force of a screwdriver to be effectively distributed across a larger surface, ensuring complete removal of the wall area by adapting the pocket's depth to the tool's penetration and incorporating stiffening elements like ribs and collars.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the wall area is made thin to reduce material usage and simplify installation, then ease of manufacture and installation is improved, but the wall area cannot be completely broken out by tool manipulation

Engineering Contradiction:
Improveease of manufactureVSAvoidease of operation
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies local quality by providing reinforcement elements (such as ribs or stiffening structures) specifically in the wall area to be broken out, while the rest of the installation part maintains thin wall thickness. This localized reinforcement enables complete break-out of the wall area by tool manipulation without requiring the entire structure to be thick, thus resolving the contradiction between ease of manufacture and ease of operation.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the wall area is reinforced to enable complete break-out by tool manipulation, then ease of operation is improved, but the structure becomes more complex and requires additional material

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the wall structure into different functional zones: a thin-walled region for ease of manufacture and installation, and a locally reinforced wall area with integration elements for complete break-out capability. This segmentation allows the structure to achieve ease of operation through targeted reinforcement without requiring complex design throughout the entire device, thus resolving the contradiction between ease of operation and device complexity.

Inventive Principle:
Principle #1Segmentation

3Force

If the wall area is reinforced with additional structures, then force distribution is improved, but manufacturing precision requirements increase

Engineering Contradiction:
ImproveforceVSAvoidmanufacturing precision
Core Design Contradiction:
ForceVSManufacturing precision

Solution Approach 1:

The patent employs composite material structures in the wall area, combining base material with integrated reinforcement elements (such as ribs or stiffening structures) that are molded or formed as part of the single component. This composite approach improves force distribution during break-out operations while maintaining relatively simple manufacturing processes, as the reinforcement elements are integrated into the molding process rather than requiring separate precision assembly steps, thus resolving the contradiction between force enhancement and manufacturing precision requirements.

Inventive Principle:
Principle #40Composite materials
