Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical connectors often suffer from stripping or breaking due to over-torquing, and existing solutions are either ineffective or require complex and costly remediation techniques, leading to difficulties in removal and collateral damage.
Innovation Solution
A powered driver bit with sensory capabilities that detects proper orientation and contact with connectors, reduces or alters power when improper contact is sensed, and includes multiple-section connector sets and anchor point matrices to distribute load and prevent over-torquing, along with driver systems that detect seating and tightness conditions to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If higher torque is applied to tighten connectors, then connection strength is improved, but connector stripping or breaking occurs
Solution Approach 1:
The patent employs feedback mechanisms through sensor-equipped driver bits that detect seating conditions and tightness levels of connectors. The system continuously monitors torque application and provides real-time feedback to the control system, which adjusts power delivery to prevent over-torquing while ensuring adequate connection strength.
Solution Approach 2:
The control system dynamically changes operational parameters (power delivery, torque limits) based on detected connector conditions. The system adapts torque thresholds and power levels according to the specific connector type, material properties, and seating status, optimizing the balance between achieving sufficient connection strength and preventing damage.
2Ease of repair
If complex remediation techniques are used to address stripped connectors, then connector extraction is improved, but device complexity and cost increase
Solution Approach 1:
The system performs preliminary detection and prevention actions before connector damage occurs. By monitoring torque and seating conditions in real-time, the system prevents stripping from happening in the first place, eliminating the need for complex extraction procedures and specialized remediation tools.
Solution Approach 2:
The driver system performs self-diagnosis and self-adjustment through integrated sensors and control logic. The system automatically detects potential issues and adjusts its operation to prevent damage, reducing the need for external inspection tools and complex remediation equipment.
3Device complexity
If driver bits without sensory capabilities are used, then device simplicity is maintained, but proper torque application and damage prevention are compromised
Solution Approach 1:
The driver bit is designed with multi-functionality, serving both as a mechanical driving tool and as a sensing device. The same bit that applies torque also contains sensors that detect seating conditions and tightness levels, eliminating the need for separate inspection tools while ensuring reliable torque application.
Solution Approach 2:
The patent merges the driving function and sensing function into a single integrated driver bit assembly. The sensor elements are incorporated directly into the bit structure, combining mechanical torque application with electrical or magnetic sensing capabilities in one unified tool.
