Adjustable Screw-In Guide for Long Screws Without Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw-in aids for long screws in wood construction often result in screws slipping out and lack functionality for adjusting angles and distances, especially during roof construction.
Innovation Solution
A screw-in aid with a triangular or quadrangular configuration, featuring grooves, latching units, spacers, and magnetized screw holders to securely guide and adjust screws, allowing multiple angles and distances for precise screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple triangular screw-in aid is used, then the device structure is simple, but the screw easily slips out and the screwing reliability is poor
Solution Approach 1:
The screw-in aid is divided into a base body and a separate screw holder that can be attached and detached. The screw holder contains the groove for receiving the screw, while the base body provides the ground engaging portion. This segmentation allows the screw holder to securely grip the screw while the base body remains simple and stable on the ground.
Solution Approach 2:
The screw holder acts as an intermediary component between the screw and the user's hand. It provides a secure grip on the screw through the groove and transfers the screwing force reliably to the screw, preventing slippage while maintaining overall device simplicity.
2Device complexity
If a fixed-angle screw-in aid is used, then the device structure is simple, but the adaptability to different screwing angles and distances is limited
Solution Approach 1:
The screw holder is designed to be displaceable along the ground engaging portion, allowing dynamic adjustment of the screwing angle and distance from the ground. The holder can be positioned at different locations and angles while maintaining secure grip on the screw, enabling adaptation to various screwing requirements without changing the basic device structure.
Solution Approach 2:
The screw-in aid can perform multiple functions by adjusting the position and angle of the screw holder. The same device can accommodate different screw lengths, angles, and distances by simply repositioning the holder, making it a universal tool for various screwing operations without requiring multiple specialized tools.
3Device complexity
If the screw holder is fixed in position, then the device structure is simple, but the ability to adjust distance to adjacent objects is limited
Solution Approach 1:
The screw holder is designed with dynamic positioning capability along the ground engaging portion. It can be displaced to different positions and locked at desired locations, allowing adjustment of the distance between the screw and adjacent objects while maintaining a relatively simple device structure without complex adjustment mechanisms.
