Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling machines face issues with maintaining the position of the lead at a predetermined angle, as existing fixing structures can be damaged when adjusting the rotation angle, and external forces can alter the lead's position, leading to malfunctions.
Innovation Solution
A lead supporting device with a hinge shaft coupling the lead to the frame, main cylinders for rotation, a rotatable guide body, and a lead position fixing unit with gripping members and uneven surfaces to securely fix the lead's position and prevent angle changes from external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate brackets and support bars are installed to fix the lead position, then the lead position can be maintained at a predetermined angle, but the structure cannot be eliminated during working and may be damaged when the cylinder is actuated
Solution Approach 1:
The patent applies the dynamics principle by designing a lead position fixing unit that can dynamically transition between fixed and movable states. The gripping members can clamp down to fix the guide rod when needed, and release to allow adjustment during operation. This dynamic capability resolves the contradiction by providing reliable fixation when required while maintaining operational flexibility when adjustment is needed.
Solution Approach 2:
The patent uses an intermediary approach by introducing a guide rod and guide body mechanism between the lead and the frame. The guide rod can be gripped by the fixing unit to establish a fixed position, but can also be released to allow the lead to move freely. This intermediary mechanism resolves the contradiction by mediating between the need for stable fixation and the need for operational adjustability.
2Reliability
If the lead position is fixed using coupling devices or support bars, then the lead position can be maintained, but peripheral devices for rotating the lead may be damaged when the cylinder is actuated
Solution Approach 1:
The patent applies dynamics by designing a system where the gripping members can dynamically clamp and release. When the lead position needs to be maintained, the gripping members clamp onto the guide rod to prevent movement. When the cylinder is actuated to adjust the lead angle, the gripping members can be released to prevent damage to peripheral devices. This dynamic control resolves the contradiction between position stability and damage resistance.
Solution Approach 2:
The patent implements beforehand cushioning by designing the gripping members to release before damage can occur. The system is configured so that when the cylinder actuates to adjust the lead angle, the gripping members are designed to release in advance, preventing the peripheral rotating devices from being damaged by the actuation force. This protective mechanism resolves the contradiction by preventing damage before it can occur.
3Reliability
If the lead position is fixed, then the lead can be maintained at a predetermined angle, but the rotation angle cannot be adjusted without risking damage
Solution Approach 1:
The patent applies the dynamics principle by designing a lead position fixing unit with gripping members that can transition between clamped and released states. When clamped, the guide rod is securely held to maintain the lead at a predetermined angle. When released, the lead can be freely adjusted to different angles. This dynamic capability resolves the contradiction by providing both reliable position fixation and angle adjustment versatility.
Solution Approach 2:
The patent uses an intermediary mechanism with a guide rod that acts as a mediator between the lead and the fixing unit. The guide rod can be gripped by the fixing unit to establish a fixed position, or released to allow angle adjustment. This intermediary mechanism resolves the contradiction by mediating between the need for stable fixation and the need for adaptability in angle adjustment.
