Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing wall plugs from surfaces often require excessive force, leading to damage of the surrounding material, as non-specialized tools like corkscrews or tweezers are used, which are inefficient and aesthetically unsatisfactory.
Innovation Solution
A device comprising a screw remover and an extractor hub, coupled together, allows for the easy extraction of wall plugs using a manual or power tool, minimizing surface damage by providing a mechanical advantage and controlled removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-specialized tools like corkscrews or tweezers are used to extract wall plugs, then the extraction can be performed, but excessive force is required which damages the surrounding surface
Solution Approach 1:
The extraction tool is divided into multiple functional components: a screw portion for engaging the wall plug, an expansion portion for applying controlled force, and a extraction portion for removal. This segmentation allows each part to perform its specific function efficiently, enabling extraction without excessive force that would damage the surrounding surface.
Solution Approach 2:
The expansion portion acts as an intermediary between the screw portion and the extraction portion, transferring and distributing the applied force evenly. This intermediary component prevents concentrated stress that would otherwise damage the surrounding surface while still providing enough force to extract the wall plug.
2Productivity
If excessive force is applied to remove wall plugs using conventional tools, then the wall plugs can be extracted, but the surrounding material is damaged
Solution Approach 1:
The tool incorporates dynamic elements including threaded engagement that progressively secures the wall plug, and an expansion mechanism that dynamically adjusts to apply optimal force. This dynamic design allows efficient extraction while maintaining control over the applied force to prevent surface damage.
3Ease of operation
If conventional extraction tools are used, then the wall plugs can be removed, but the process requires significant manual effort and force
Solution Approach 1:
The tool replaces direct manual pulling force with a threaded mechanical engagement system. The screw portion engages with the wall plug through threading, converting rotational motion into linear extraction force. This mechanical substitution reduces the direct manual effort required while maintaining effective extraction capability.
