Solution Overview
Problem
Existing drive units for ice making devices face challenges in electrically connecting circuit boards and drive mechanisms through partition members without obstructing the mounting process, as wiring often becomes an obstacle when extending outside the case.
Innovation Solution
A drive unit design featuring a partition member with penetration parts and terminal holders, where the terminal holder is supported by holder support parts on both sides, allowing for secure and stable electrical connection between the circuit board and drive mechanism, preventing disconnection and facilitating easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wiring is extended outside the case for electrical connection, then electrical connection between circuit board and drive mechanism is achieved, but wiring becomes an obstacle during mounting
Solution Approach 1:
The partition member serves as an intermediary structure that integrates both electrical connection and mechanical support functions. By incorporating penetration parts and terminal holders directly into the partition member, the invention eliminates the need for separate wiring extensions, thus resolving the contradiction between achieving reliable electrical connection and maintaining ease of mounting operation
Solution Approach 2:
The invention merges the electrical connection function with the structural partition function. The terminal holder is integrated into the partition member, combining what were previously separate components (wiring and partition structure) into a unified assembly that achieves both electrical connectivity and structural integrity without interfering with the mounting process
2Reliability
If terminal holder is secured in penetration part, then electrical connection stability is improved, but assembly complexity increases
Solution Approach 1:
The partition member is segmented to include integrated penetration parts and terminal holders as built-in features rather than separate components. This segmentation approach allows the terminal holder to be securely formed within the partition structure itself, achieving connection stability without adding external assembly complexity
Solution Approach 2:
The terminal holder is designed to be self-securing within the penetration part through the integrated structure of the partition member. The holder support parts provide automatic positioning and retention, eliminating the need for additional fastening mechanisms or complex assembly steps, thus maintaining simplicity while ensuring stability

AI summary
A drive unit for an ice making device comprises a partition member formed with a penetration part, a circuit board disposed on one side with respect to the partition member, a drive mechanism disposed on the other side with respect to the partition member, and a terminal holder disposed on an inner side of the penetration part. The partition member comprises a first holder support part which supports a first side face of the terminal holder with elasticity, and a second holder support part which supports a second side face of the terminal holder. The terminal holder comprises a first engaging protruded part which is engaged with an end part of the first holder support part, and the first holder support part comprises a first guide groove which guides the first engaging protruded part when the terminal holder is inserted into the penetration part.
