Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If current is transmitted through electrical connectors and circuit boards with long transmission paths, then the power distribution device can be assembled with standard components, but current loss increases and large current transmission becomes difficult
Solution Approach 1:
The patent extracts the current transmission function from the traditional circuit board pathway and creates a separate, dedicated transmission mechanism. This involves removing current transmission from the signal pathway and establishing independent current transmission elements that directly connect power supply units to output elements, bypassing the circuit board's limited current capacity and long transmission path.
Solution Approach 2:
The patent segments the power distribution function into separate components: signal transmission elements for control signals and power transmission elements for current. This segmentation allows each element to be optimized for its specific function, with current transmission elements having sufficient current capacity and short transmission paths, while signal elements handle control functions.
2Power
If copper foil thickness is increased to transmit large current, then large current transmission capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the current transmission function with dedicated transmission elements that are specifically designed for high current capacity. Instead of relying on standard circuit board copper foil, the invention integrates current transmission pathways directly into the circuit board structure or uses separate transmission elements that are optimized for current carrying capacity without requiring excessive copper thickness.
Solution Approach 2:
The patent transitions from planar current transmission on circuit boards to three-dimensional transmission pathways. This involves creating vertical or layered current transmission routes that reduce the effective transmission distance and allow for more efficient current distribution without increasing copper foil thickness in the traditional plane.
3Adaptability or versatility
If numerous components are used in the power distribution device, then functional requirements are met, but assembly complexity increases and assembly time is extended
Solution Approach 1:
The patent creates transmission elements that serve multiple functions: signal transmission elements handle control signals while power transmission elements handle current. This multi-functionality reduces the total number of components needed, as each element is designed to handle its specific type of transmission efficiently, eliminating the need for separate dedicated components for each function.
Solution Approach 2:
The patent designs the circuit board and transmission elements during the manufacturing process to inherently provide the necessary transmission paths. This preliminary action embeds the current and signal transmission capabilities directly into the board structure during manufacturing, rather than requiring separate assembly steps to install additional transmission components, thereby reducing assembly complexity and time.
