Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional assembly methods are used to connect acoustic transmitters with flexible printed circuit boards, then manufacturing complexity increases, but assembly simplicity deteriorates
Solution Approach 1:
The device is divided into separate modular components: the acoustic transmitter, the flexible printed circuit board, and the resilient holder are distinct elements that can be manufactured independently and then assembled together using simple snap-fit or press-fit connections, reducing overall manufacturing complexity
Solution Approach 2:
The resilient holder acts as an intermediary component that facilitates the connection between the acoustic transmitter and the flexible printed circuit board. This intermediate element simplifies the assembly process by providing a pre-formed interface that requires no complex bonding or soldering operations
2Productivity
If product design is standardized, then manufacturing efficiency improves, but product differentiation capability deteriorates
Solution Approach 1:
The resilient holder and basic pen structure are designed as universal components that can accommodate different acoustic transmitter models and configurations. This allows the core manufacturing process to remain standardized while enabling product differentiation through various transmitter options and cover element designs
Solution Approach 2:
The product design incorporates dynamic elements such as interchangeable cover elements and selectable switching modes that allow customization after the base manufacturing is complete. This enables efficient standardized production of core components while maintaining flexibility for product differentiation
3Reliability
If acoustic transmitter is permanently attached to circuit board, then connection reliability improves, but assembly ease deteriorates
Solution Approach 1:
The resilient holder incorporates elastic or spring-loaded elements that provide pre-compression force to maintain reliable electrical and mechanical connections between the acoustic transmitter and the circuit board. This beforehand cushioning ensures connection reliability without requiring permanent attachment methods
4Adaptability or versatility
If switch assembly has multiple switching modes, then functionality increases, but device complexity increases
Solution Approach 1:
Multiple switching modes are combined into a single integrated switch assembly with multiple contacts or positions. This merging of functions into one component achieves enhanced functionality while minimizing the increase in device complexity compared to using separate switches for each mode
