Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual polishing of aluminum alloy wheels is inefficient and fails to ensure smooth corner finishes due to small corner fillets and insufficient film coverage, particularly at bolt hole, valve hole, outer rim, and cap section corners, leading to corrosion issues.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual polishing is used for wheel corners, then operational flexibility is maintained, but polishing efficiency is low and consistency cannot be guaranteed
Solution Approach 1:
The polishing device is divided into multiple independent polishing modules, each equipped with a polishing head that can be independently controlled. This segmentation allows simultaneous polishing of multiple wheel corners, dramatically increasing productivity while maintaining manageable system complexity through modular architecture
Solution Approach 2:
The polishing device is designed as a multi-functional system capable of polishing various wheel corner types (bolt holes, valve holes, outer rim corners, cap section corners) using the same platform. The universal design achieves high productivity across different wheel configurations without requiring separate dedicated devices for each corner type
2Manufacturing precision
If manual polishing is used, then equipment simplicity is maintained, but corner smoothness and film coverage consistency cannot be ensured
Solution Approach 1:
The polishing device incorporates sensors that detect wheel corner positions and polishing quality in real-time, providing feedback to the control system. This feedback mechanism ensures consistent corner smoothness and film coverage by automatically adjusting polishing parameters, achieving high manufacturing precision through a controlled complex system
Solution Approach 2:
The system replaces manual mechanical polishing with automated polishing heads driven by controlled mechanisms. This substitution ensures uniform polishing pressure and consistent motion patterns, guaranteeing corner smoothness and film coverage consistency that cannot be achieved through manual operations
3Reliability
If automated polishing is implemented for all corner positions, then polishing consistency is improved, but device complexity increases
Solution Approach 1:
The automated polishing system is divided into separate polishing modules for different corner positions (bolt holes, valve holes, outer rim, cap sections). Each module operates independently with its own polishing head, ensuring consistent quality at each position while keeping individual module complexity manageable through modular design
Solution Approach 2:
A universal polishing platform performs all corner polishing operations using standardized polishing heads and control mechanisms. This multi-functional approach achieves reliable consistent results across all corner types without requiring entirely separate systems for each position, balancing reliability with controlled complexity
