Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The weight applicator is designed to automatically detect wheel parameters, apply adhesive, position weights, and verify balance without human intervention. The system performs self-service functions including automated weight selection, application force control, and balance verification, eliminating the need for human operators while maintaining precise control over the balancing process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The weight applicator integrates multiple functions into a single automated device: it detects wheel parameters, applies adhesive to the weight, positions the weight on the wheel, compresses it for bonding, and verifies balance. This multi-functional integration achieves high automation while managing device complexity through consolidated operations

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

2Productivity
