Installation Part Wall Area Breakout Stiffening
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Force
If the wall area is reinforced with additional structures, then force distribution is improved, but manufacturing precision requirements increase
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.
