Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldered connections are used to connect consumers to contact surfaces, then electrical connection reliability is improved, but ease of operation deteriorates and device complexity increases
Solution Approach 1:
The device is segmented into modular components: a support element with conductor tracks, contact surfaces for power supply, and a plug for consumer connection. This segmentation allows the plug to be a separate, easily replaceable component rather than requiring permanent soldered connections, thus improving ease of operation while maintaining reliable electrical contact through dedicated contact surfaces.
Solution Approach 2:
The plug acts as an intermediary component between the power supply system and the consumer. Instead of directly soldering the consumer to the contact surfaces, the plug provides a standardized interface that simplifies connection while ensuring reliable electrical contact through its design with dedicated contact surfaces.
2Reliability
If soldered connections are used to connect consumers to contact surfaces, then electrical connection reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The device is segmented into modular components that can be manufactured separately and assembled. The support element with conductor tracks and contact surfaces can be manufactured as a complete unit, and the plug can be manufactured separately and then connected. This segmentation simplifies the manufacturing process compared to requiring precise soldering operations for each connection.
Solution Approach 2:
The support element is designed with self-adhesive properties, allowing it to be easily attached to carriers or surfaces without requiring complex manufacturing processes. The plug and contact surfaces are designed to work together automatically when connected, reducing the need for specialized assembly skills.
3Adaptability or versatility
If consumers are replaced by detaching soldered connections, then adaptability is improved, but loss of time increases and productivity decreases
Solution Approach 1:
The modular design with a separate plug component allows consumers to be quickly disconnected and replaced by simply detaching the plug, rather than requiring time-consuming desoldering and resoldering operations. This segmentation enables rapid consumer replacement while maintaining reliable electrical connections.
Solution Approach 2:
The design allows for easy discarding of old consumers and recovery of the plug component. The plug remains with the support element and can be reused with different consumers, reducing waste and enabling quick replacement without losing the connection infrastructure.
4Shape
If a flat plug design is used, then visual appearance is improved, but device complexity increases
Solution Approach 1:
The plug is permanently connected to the support element, merging these two components into a single integrated unit. This eliminates the need for separate mounting hardware and reduces overall device complexity while achieving a flat, visually appealing design that can be easily attached to carriers.
Solution Approach 2:
The plug design with conductor tracks and contact surfaces creates a standardized interface that can be replicated and integrated into different support element configurations. This standardized copying of the plug design simplifies manufacturing and assembly while maintaining a consistent, clean visual appearance.
