Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vast array of structural adhesives with specifically chosen properties is provided to meet customer requirements, then customer needs are met, but inventory requirements increase significantly
Solution Approach 1:
The adhesive system is divided into modular components: a base adhesive formulation and separate property adjustment components. This segmentation allows customers to combine the base adhesive with different property modifiers to achieve desired characteristics without maintaining separate inventories for each adhesive variant.
Solution Approach 2:
The base adhesive formulation is designed to be universal and can be combined with multiple different property adjustment components to meet various customer requirements. This multi-functional approach replaces the need for multiple specialized adhesive formulations in inventory.
2Adaptability or versatility
If a vast array of structural adhesives with specifically chosen properties is provided, then customer needs are met, but costs increase
Solution Approach 1:
By segmenting the adhesive system into a base formulation and separate property adjustment components, the manufacturing cost is reduced compared to producing multiple complete adhesive formulations. The base adhesive is manufactured once and can be combined with different property modifiers as needed.
Solution Approach 2:
Instead of manufacturing different adhesives with different properties, the invention changes parameters of a single base adhesive formulation by adding different property adjustment components. This parameter-based customization approach is more cost-effective than producing multiple fixed formulations.
3Adaptability or versatility
If a vast array of structural adhesives with specifically chosen properties is provided, then customer needs are met, but knowledge requirements and verification needs increase
Solution Approach 1:
The adhesive system is segmented into a base formulation and separate property adjustment components, simplifying the knowledge structure. Instead of needing to understand multiple complete adhesive formulations, users only need to understand the base adhesive and which property modifiers to add for desired characteristics.
Solution Approach 2:
The base adhesive formulation acts as an intermediary that can be combined with different property adjustment components. This intermediary approach simplifies the system by providing a consistent base that mediates between the customer's needs and the available property modifiers.
