Solution Overview
Problem
Refrigeration appliance manufacturers face challenges in creating distinct models with varying external appearances while maintaining cost-effectiveness, as complex molds for custom door components are expensive and limit design flexibility.
Innovation Solution
A modular door component design featuring thin-walled, decorative elements that can be easily attached to standard side panels, allowing for varying external appearances without additional static functions or anchoring requirements, enabling the use of simple and inexpensive manufacturing tools and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom injection molds are used for each built-in part to achieve design freedom and individual character, then the external appearance can be customized, but the production cost increases significantly
Solution Approach 1:
The built-in part is divided into two functional segments: a standardized carrier body (base) and a model-specific decorative element (cover). The carrier body remains uniform across all models, while the decorative element varies by model to provide individual character. This segmentation eliminates the need for custom injection molds for each model while maintaining design freedom.
2Ease of manufacture
If modular components are used to reduce mold costs, then production cost decreases, but the side walls remain complex in shape requiring expensive custom molds
Solution Approach 1:
The complex decorative outer shell is extracted as a separate standardized component that can be produced with simple molds. The underlying carrier body retains the necessary structural complexity for functionality but is manufactured separately. This allows the complex shaping to be achieved through assembly rather than complex molding.
3Ease of manufacture
If standardized components are used across different models, then production cost decreases, but the individual character of different models is lost
Solution Approach 1:
The standardized carrier body provides uniform structural quality across all models, while the decorative element applied to each carrier body provides local visual differentiation. This allows the majority of the component (carrier body) to be manufactured standardly, while only the visible surface (decorative element) varies by model to maintain individual character.
