Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual burr removal is used, then operational flexibility is maintained, but manufacturing precision and product consistency deteriorate due to deformation and manual error

Engineering Contradiction:
Improveoperational flexibilityVSAvoidburr removal consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical burr removal with an automated system using a servo motor-driven rotating tool that applies controlled mechanical force. The ranging sensor detects burr position and the controller automatically adjusts tool position and force, eliminating manual error while maintaining operational flexibility through programmable control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-adjustment through the ranging sensor that automatically detects burr location and depth, feeds this information to the controller, which then self-corrects tool position and applying force. This closed-loop self-service mechanism ensures consistent burr removal without manual intervention while adapting to each workpiece's specific conditions.

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual burr removal is used, then device complexity is low, but productivity and efficiency deteriorate due to incomplete coverage and rework

Engineering Contradiction:
Improvesystem simplicityVSAvoidburr removal efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent implements continuous automatic rotation of the workpiece via servo motor while the burr removal tool continuously engages with the riser edge. The system maintains continuous useful action through automated positioning and force application, eliminating interruptions and ensuring complete coverage without manual repositioning, thereby significantly improving productivity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The automated device integrates multiple functions into a single system: the servo motor provides both workpiece rotation and tool positioning, the ranging sensor performs detection and feedback, and the controller coordinates all operations. This multi-functional integration achieves high productivity while keeping the overall device structure relatively simple and compact.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If inconsistent burr removal is performed, then operational simplicity is maintained, but reliability deteriorates due to increased corrosion risk and poor paint coverage

Engineering Contradiction:
Improveoperational simplicityVSAvoidcorrosion protection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent incorporates a ranging sensor that provides real-time feedback on burr position, depth, and removal status. This feedback loop allows the controller to continuously adjust tool position and applying force to ensure complete and consistent burr removal. The feedback mechanism guarantees reliable results by verifying each burr's complete elimination before proceeding, eliminating corrosion risks from incomplete removal.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system replaces unpredictable manual mechanical removal with controlled automated mechanical action. The servo motor provides precise, repeatable force application while the ranging sensor ensures consistent positioning. This substitution of manual operation with automated mechanical control delivers reliable and consistent burr removal that protects against corrosion and ensures proper paint adhesion.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a left sliding plate to move, a clamping wheel is controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheel, so that the wheel can rotate while being clamped. When a distance adjusting cylinder drives a right sliding block to move, a left sliding block and the right sliding block move synchronously under the action of a feed gear rack structure, so that a left burr tool and a right burr tool move synchronously to adjust the distance between the tools according to the diameter of a cap slot, which solves the problem of inconsistency of the riser after the burrs are removed from the wheel.
