Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener tools often experience slippage during tightening or loosening due to worn fasteners, corrosion, or damage, leading to inefficiencies and the need for additional tools like bolt extractors that require drilling.
Innovation Solution
A ball-shaped bit with a bevel edge design that engages the fastener head, allowing torque application without slippage and enabling angled rotation, eliminating the need for bolt extractors by providing a multi-grip socket bit compatible with various torque tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional driver bit is used to tighten or loosen fasteners, then the operation is simple and straightforward, but slippage occurs during torque application due to worn or damaged fastener heads
Solution Approach 1:
The driver bit features a spherical engagement tip with curved contact surfaces that conform to the fastener head geometry. This spherical design allows the bit to self-align and maintain continuous contact with the fastener head during torque application, preventing slippage while preserving ease of operation through automatic alignment.
Solution Approach 2:
The engagement surfaces of the driver bit are designed with asymmetric bevel edges that match the asymmetric geometry of typical fastener heads. This asymmetric configuration ensures optimal contact distribution and torque transfer while accommodating variations in fastener head conditions such as wear or damage.
2Adaptability or versatility
If a standard straight bit is used, then the tool design is simple, but it cannot access fasteners in hard-to-reach areas
Solution Approach 1:
The driver bit incorporates a spherical engagement tip that enables angular orientation relative to the fastener head, adding a rotational dimension to the otherwise linear tool-shaft alignment. This allows the bit to access fasteners in confined spaces and hard-to-reach areas while maintaining a relatively simple overall tool design.
3Adaptability or versatility
If bolt extractors are used to remove damaged fasteners, then extraction capability is achieved, but additional drilling and specialized tools are required
Solution Approach 1:
The driver bit is designed with a universal engagement mechanism that can effectively grip and remove various types of fasteners including damaged, stripped, or corroded ones. The spherical tip with bevel edges provides multi-functional capability to handle different fastener conditions without requiring specialized extraction tools or drilling operations.

AI summary
A screw bit body which allows for efficient torque force application onto a socket fastener from a variety of angles. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a concave surface, a convex surface, and an engagement cavity. The convex surface is adjacent to the first base and the concave surface is adjacent to the second base to create a ball-like shape. The engagement cavity creates a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base.
