Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection structures for electronic components and electrically conductive flat square bodies face difficulties in ensuring reliable connections without bending, especially as components and connectors become smaller in size.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crimp piece is used to pierce and fix the electrically conductive flat square body, then the connection is secured, but the connector size increases making it difficult to achieve smaller component sizes
Solution Approach 1:
The piercing piece is divided into multiple thin plate-shaped piercing edges arranged in parallel, allowing the connection function to be distributed across multiple small elements rather than requiring a single large crimp piece. This segmentation enables smaller overall connector size while maintaining reliable connection through cumulative piercing action
Solution Approach 2:
A plate with insertion openings is introduced as an intermediary component between the piercing terminal and the electrically conductive flat square body. This plate mediates the connection by providing guided insertion paths and positioning features, enabling secure connection without requiring a large crimping mechanism
2Volume of moving object
If the connector size is reduced to accommodate smaller electronic components, then component miniaturization is achieved, but the bend formation of the crimp piece becomes difficult
Solution Approach 1:
The bend formation step is extracted and eliminated from the manufacturing process. Instead of requiring the crimp piece to be bent and formed, the invention uses pre-formed thin plate-shaped piercing pieces that are simply inserted through the plate openings, completely removing the complex bend formation operation from the manufacturing sequence
Solution Approach 2:
The piercing piece geometry is changed from a thick crimpable form to a thin plate shape with multiple piercing edges. This parameter change in thickness and cross-sectional geometry makes the piece suitable for direct insertion without bending, while the thin plate shape maintains flexibility for insertion through small openings
3Reliability
If multiple piercing pieces are used to ensure reliable connection, then connection security improves, but the risk of pieces slipping increases
Solution Approach 1:
The plate with insertion openings serves as a mediator that prevents the piercing pieces from slipping. The openings provide physical constraints and frictional resistance that hold the thin plate-shaped piercing pieces in place, ensuring stable positioning while allowing multiple pieces to be used for enhanced connection security
Solution Approach 2:
The insertion openings in the plate are designed with asymmetric features including positioning protrusions and corresponding recesses, as well as friction-resistant surface profiles. This asymmetric geometry prevents the piercing pieces from slipping laterally while allowing insertion from one direction, providing stable positioning for multiple piercing pieces
