Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packages are used for abrasive wheels, then the wheels are protected from atmospheric agents, but the empty packages occupy excessive transportation space and cannot be efficiently stacked when filled
Solution Approach 1:
The base is designed with a frustoconical shape that allows empty bases to be nested inside one another during transportation, significantly reducing the volume occupied by empty packages. The tapered geometry enables one base to fit within another, creating a compact nested arrangement that minimizes transportation space while maintaining protection capabilities when the packages are filled and stacked.
2Reliability
If conventional packages are used for abrasive wheels, then the wheels are protected from atmospheric agents, but the packages cannot be efficiently stacked together when filled
Solution Approach 1:
The base employs asymmetric geometry with a frustoconical shape featuring a specific half-cone angle (0.5° to 4°), creating an asymmetric profile that enables efficient stacking. The asymmetric design allows the base to fit into the cover and subsequent bases in a tapered arrangement, optimizing stacking efficiency and space utilization when multiple packages are stacked together while maintaining atmospheric protection.
3Productivity
If the base has a frustoconical shape with specific angle, then stacking efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The invention specifies a range for the half-cone angle (0.5° to 4°, preferably 1° to 3°) rather than a single precise value, allowing manufacturing flexibility while achieving the desired stacking efficiency. This parameter range approach balances manufacturing precision requirements with functional performance, enabling efficient stacking without imposing overly stringent tolerances that would increase manufacturing complexity and cost.
