Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single supply head with multiple nozzles is used to cover the entire predetermined region, then the adhesive application coverage is improved, but the flow paths become complicated and prone to clogging
Solution Approach 1:
The single supply head with multiple nozzles is divided into multiple independent supply heads, each with a single nozzle. This segmentation simplifies the flow paths of each supply head, reducing the complexity and susceptibility to clogging, while collectively maintaining comprehensive adhesive application coverage through coordinated operation of multiple supply heads.
2Area of stationary object
If a single supply head with multiple nozzles is used to cover the entire predetermined region, then the adhesive application coverage is improved, but the path difference of each flow path becomes large causing variation in adhesive discharge
Solution Approach 1:
By segmenting the supply system into multiple independent supply heads with single nozzles, each supply head has a short and uniform flow path. This eliminates the large path differences that would otherwise cause variation in adhesive discharge, ensuring consistent adhesive application across the entire predetermined region.
3Productivity
If multiple nozzles are provided in a single supply head, then the adhesive application efficiency is improved, but the maintenance work time and labor increase
Solution Approach 1:
The supply head is segmented into multiple independent units, each with a single nozzle. This segmentation simplifies maintenance operations, allowing individual nozzles to be quickly accessed and cleaned without disassembling complex flow paths. Consequently, maintenance time and labor are reduced while adhesive application efficiency is maintained through parallel operation of multiple supply heads.
4Manufacturing precision
If the flow paths are simplified by using individual supply units, then the adhesive discharge consistency is improved, but the number of supply units increases
Solution Approach 1:
While segmentation increases the number of supply units, each unit is designed to be simple and modular. The standardized design of individual supply heads allows for easy coordination and control, managing the overall system complexity. The benefit of consistent adhesive discharge from each simplified flow path outweighs the increase in the number of units.
