Innovation Solution
A connection adapter with a printed circuit board featuring a comb-shaped line structure and an electrical connector interface, allowing for efficient connection using pre-assembled multi-pole cables and connectors, such as FLK, D-SUB, or Fujitsu FCN, which can be mechanically fixed to screw terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual connection lines are connected to screw terminals one by one, then reliable electrical connection is achieved, but the connection process becomes time-consuming and uncomfortable
Solution Approach 1:
The invention divides the connection process into two segments: a first connection element with multiple connection lines and a second connection element with multiple screw terminals. By separating these elements and allowing the first element to be connected as a unit to the second element, the patent enables simultaneous connection of multiple lines while maintaining individual terminal reliability through screw fastening.
Solution Approach 2:
The patent combines multiple individual connection lines into a single integrated first connection element that can be connected to multiple screw terminals simultaneously. This merging approach allows parallel connection of all lines during a single operation, eliminating the need for sequential individual connections while maintaining reliable electrical contact at each terminal.
2Reliability
If multiple individual connection lines are connected to terminal blocks, then electrical connectivity is established, but the overall system complexity increases
Solution Approach 1:
The invention merges multiple individual connection operations into a single integrated connection element that interfaces with multiple terminals simultaneously. This reduces the number of separate connection components and simplifies the overall connection system architecture while maintaining all necessary electrical pathways.
Solution Approach 2:
The first connection element is designed as a universal interface that can simultaneously connect to multiple screw terminals, serving multiple functions in a single component. This multi-functional design reduces the need for multiple specialized connection devices, thereby simplifying the overall system complexity.
3Productivity
If pre-assembled multi-pole cables with connectors are used, then connection efficiency is improved, but the cost of the connection system increases
Solution Approach 1:
The invention segments the connection system into a reusable first connection element that can be attached to different multi-pole cables. This segmentation allows the expensive connector part to be shared across multiple cables, reducing the overall system cost while maintaining high connection efficiency through the reusable interface.
Solution Approach 2:
The patent employs a design where the first connection element can be easily attached and detached, allowing the use of simpler, less expensive cable assemblies that can be replaced if needed, while the durable connector interface is reused. This approach reduces the cost of individual cable components while maintaining connection efficiency through the robust reusable connector.
