Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a projection-shaped terminal is inserted into a recess for easy attachment and detachment, then ease of operation is improved, but reliability of electric connection deteriorates
Solution Approach 1:
The power supply terminal is divided into distinct functional segments: a projection-shaped body portion for insertion, a terminal portion for electrical contact, and an elastic portion for securing. This segmentation allows each component to perform its specific function optimally - the projection shape enables easy attachment/detachment while the elastic portion ensures reliable electrical connection through continuous contact pressure.
Solution Approach 2:
The elastic portion changes its physical state from a deformed condition (during insertion) to a recovered condition (after insertion), utilizing elastic deformation to generate securing force. This parameter change allows the terminal to transition from a simple insertion motion to a secure, spring-loaded electrical connection, simultaneously achieving ease of operation and connection reliability.
2Ease of operation
If the conductive member protrudes outward for easy insertion, then ease of operation is improved, but stability of the object's composition deteriorates
Solution Approach 1:
The solution moves the stability mechanism from the horizontal insertion dimension to the vertical elastic deformation dimension. The elastic portion extends in a direction perpendicular to the insertion direction, allowing the terminal to be easily inserted horizontally while the elastic portion provides vertical securing force through elastic recovery, thus achieving both ease of operation and structural stability.

AI summary
A power supply rail includes a groove extending in a first direction in a base portion and having an opening on a one-end side in a second direction, a conductive portion provided at a bottom surface of the groove, and a first recess formed on a first side wall of the groove. A power supply terminal is attachable/detachable into/from the groove, and includes terminal portions formed on an other-end side in the second direction of a body portion, a lead-wire portion from the terminal portions and elastic portions provided on a first side surface of the body portion. The elastic portions are latched in contact with an inside of the first recess of the power supply rail, and the terminal portions contact with the conductive portion.
