Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connectors often damage printed circuit boards during transportation due to collisions with the housing, affecting their performance.
Innovation Solution
The electric connector features an insulative housing with barriers forming a clamping space, where the printed circuit board is securely positioned, and conductive terminals with soldering portions to ensure stable fixation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the printed circuit board is not secured to the housing, then the assembly process is simple, but the printed circuit board may collide with the housing during transportation and cause damage
Solution Approach 1:
The housing is divided into an insulative housing and a metal housing, with the metal housing forming a protective cage around the printed circuit board. This segmentation allows the insulative housing to maintain assembly simplicity while the metal housing provides structural protection during transportation.
Solution Approach 2:
The metal housing is designed with a protective cage structure that surrounds the printed circuit board before transportation occurs. This pre-established protective structure prevents collisions and damage during handling and transport, addressing the reliability issue without complicating the assembly process.
2Reliability
If the printed circuit board is secured to the housing, then the printed circuit board is protected during transportation, but the assembly process becomes more complex
Solution Approach 1:
The protective function is merged into the metal housing structure itself, which forms an integrated protective cage around the printed circuit board. This eliminates the need for separate securing mechanisms, maintaining reliability while avoiding increased assembly complexity.
Solution Approach 2:
The metal housing serves multiple functions: it provides structural support, electrical shielding, and physical protection during transportation. This multi-functionality allows the housing to protect the printed circuit board without requiring additional dedicated securing components.
3Reliability
If a protective structure is added for the printed circuit board, then transportation damage is prevented, but the device complexity increases
Solution Approach 1:
The protective structure is merged with the existing housing design by using the metal housing to form a protective cage. This integration ensures that the protective function is achieved without adding separate structural components, thereby preventing transportation damage while maintaining structural simplicity.
Solution Approach 2:
The design allows the printed circuit board to be freely positioned within the protective cage during assembly, with the metal housing providing flexible protection. This dynamic approach enables the protective structure to adapt to different assembly configurations without requiring complex fixed mounting mechanisms.
