Solution Overview
Problem
The existing detection tools fail to accurately determine the position and depth of threaded holes in steering knuckles, which is crucial for proper assembly of sensors, leading to potential assembly issues.
Innovation Solution
A comprehensive detection tool comprising a base, detection pin, sliding sleeve, jack screws, positioning pin, guide sleeve, and spring, which allows for precise detection of threaded hole position and depth by matching the threaded section with the detected element and utilizing a spring for uniform contact, enabling qualification of hole position and depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a simple detection tool is used, then the device complexity is low, but the measurement precision of threaded hole position and depth is insufficient
Solution Approach 1:
The detection tool employs a nested structure where the detection pin is inserted into the sliding sleeve, which is then inserted into the detection hole. The positioning pin is fitted into the guide sleeve with tight clearance (0.005mm), and the jack screw is inserted into the sliding chute. This nested arrangement allows multiple detection functions to be integrated in a compact form, achieving high measurement precision without excessive device complexity
Solution Approach 2:
The sliding sleeve acts as an intermediary component between the detection pin and the base. It features a sliding chute that guides the jack screw, and its inner hole matches the detection section of the pin. This intermediary structure enables precise transmission of the detection pin's position and depth information while maintaining overall structural compactness
2Adaptability or versatility
If multiple detection functions are integrated into one tool, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The detection tool is designed as a universal multi-functional device that can detect both the position and depth of threaded holes, as well as verify sensor mounting hole positions. The detection pin with its threaded section can engage with various threaded holes in the steering knuckle, while the sliding sleeve and jack screw mechanism enable depth measurement. This multi-functionality is achieved through a unified structure rather than separate tools
Solution Approach 2:
The tool combines multiple detection functions into a single integrated device. The positioning pin and guide sleeve are combined to provide precise lateral positioning, while the jack screw and sliding chute combination enables depth measurement. The detection pin integrates both position detection (through its shaft) and depth detection (through the threaded section engagement with the jack screw) capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool effectively detects the position and depth of threaded holes, ensuring accurate assembly of sensors by determining if the threaded hole is correctly positioned and meets the required depth, thereby preventing assembly failures.

AI summary
A comprehensive detection tool for a steering knuckle includes a base, a detection pin, a sliding sleeve, a first jack screw, a positioning pin, a guide sleeve and a spring. When the comprehensive detection tool is used, under the action of the spring, the conical portion of the positioning pin contacts a reference hole B of a detected element; and the bottom surface of the base is closely clung to a reference surface A of the detected element; the threaded section of the detection pin is inserted into a left hole on the base, and then a handle is rotated to allow the threaded section to mate with the threads of the detected element.
