Ice-Making Tray Frame Wiring Support Against Side-Plate Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ice making devices face challenges in handling wiring efficiently and preventing damage to the side plate during twist operations, as the wiring is not adequately supported, leading to stress concentration and potential damage when a penetration part is formed in the side plate.
Innovation Solution
The design includes a penetration part in the side plate to support the wiring, which is drawn along the inner surface and then outside through the penetration part, and attachment parts on the opposite side to distribute the force applied during twist operations, preventing stress concentration and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a penetration part is formed in the side plate to support the wiring, then wiring handling becomes easier, but stress concentrates in the vicinity of the penetration part and the side plate may be damaged
Solution Approach 1:
A wiring support part is introduced as an intermediary component between the side plate and the wiring. This support part extends from the inner surface of the side plate to support the wiring, allowing the penetration part to be positioned away from high-stress areas while still providing adequate wiring support. The wiring support part acts as a mediator that transfers the support function from the side plate structure to a dedicated component, reducing stress concentration on the side plate.
Solution Approach 2:
The side plate is divided into functionally distinct regions: a penetration part for wiring passage positioned away from high-stress areas, and a separate wiring support part for supporting the wiring. This segmentation allows each part to be optimized for its specific function - the penetration part for wiring access and the support part for wiring stabilization - while distributing structural stresses away from the penetration area.
2Device complexity
If the wiring is drawn directly from the drive unit to the outside of the frame without support, then the structure is simpler, but much time and effort is required for handling the wiring
Solution Approach 1:
The wiring support part serves as an intermediary structure that guides and supports the wiring from the drive unit to the outside of the frame. This intermediate support structure prevents the wiring from sagging or tangling, making handling significantly easier while adding only minimal structural complexity. The support part creates a defined pathway for the wiring, reducing the effort required for installation and maintenance.
3Adaptability or versatility
If a penetration part is formed in the side plate, then the wiring can be drawn through the side plate, but stress concentrates in the vicinity of the penetration part during twist operations
Solution Approach 1:
The side plate structure is segmented into a penetration part for wiring routing and a wiring support part for mechanical support. The penetration part is positioned away from high-stress regions to maintain wiring routing flexibility, while the separate wiring support part provides structural reinforcement without interfering with the penetration function. This segmentation decouples the wiring access function from the structural load-bearing function.
Solution Approach 2:
The wiring support part acts as an intermediary element that allows the penetration part to be located in a low-stress area while still providing adequate wiring support. The support part mediates between the wiring routing requirement and the structural integrity requirement, enabling the penetration part to be positioned optimally for wiring access without compromising side plate strength during twist operations.
