Solution Overview
Problem
Existing ice making devices face challenges in assembly workability and connection accuracy due to soldering of lead wires between circuit boards, leading to increased device size and complexity.
Innovation Solution
The device employs inter-board connectors to connect first and second boards vertically, eliminating the need for lead wires and allowing flexible arrangement of components, with the first board handling power conversion and mechanical functions, and the second board managing control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lead wires are used for connection between boards, then connection flexibility is improved, but device size is increased
Solution Approach 1:
The patent extracts and eliminates lead wires from the connection system between boards. By removing the lead wire component entirely and replacing it with direct board-to-board connectors, the invention reduces device size while maintaining connection functionality through alternative means.
Solution Approach 2:
The patent replaces the mechanical lead wire connection system with an electrical direct-connect system. Instead of using flexible mechanical lead wires, the invention uses rigid electrical connectors integrated into the board structures, substituting one connection mechanism with another that achieves the same electrical connectivity without the space requirements of lead wires.
2Manufacturing precision
If soldering of lead wires is used for board connection, then connection accuracy is improved, but workability of assembling work is deteriorated
Solution Approach 1:
The patent segments the connection function into separate board-integrated connectors rather than using separate lead wires requiring soldering. Each board has its own connector elements, allowing for modular assembly where boards can be connected directly without complex soldering operations on thin lead wires.
Solution Approach 2:
The patent introduces board-integrated connectors as intermediary elements that facilitate direct connection between boards. These connectors serve as built-in mediators that eliminate the need for external lead wires and soldering processes, simplifying the assembly workflow while ensuring reliable electrical connections.
3Device complexity
If boards are arranged on the same plane, then connection simplicity is improved, but device size is increased
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement of boards to a three-dimensional stacked configuration. By arranging boards vertically on different planes and using through-board connectors, the invention achieves compact spatial utilization while maintaining simple electrical connections through the vertical dimension.
