Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for assembling household appliances, such as hobs, face challenges in achieving an inexpensive design with improved properties, particularly in terms of storage costs and flexibility in mounting touch control units with varying weights and spring constants.
Innovation Solution
A system comprising a base body made of plastic, designed to absorb the weight of touch control units and hold them in a fixed position, with different spring constants for each type of touch control unit, allowing for flexible storage and configuration, and featuring spring elements and spacer elements for precise positioning and force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different types of touch control units with varying weights and spring constants are used, then functionality and signal detection precision are improved, but storage costs and logistics complexity increase
Solution Approach 1:
The base body is designed as a universal mounting structure that can accommodate multiple types of touch control units (first type with lower weight and spring constant, second type with higher weight and spring constant) through a standardized interface. This allows the same base body to support different touch control unit configurations without requiring separate mounting structures for each type, thereby reducing logistics complexity while maintaining the ability to detect signals precisely from different unit types
2Adaptability or versatility
If touch control units are mounted with different spring constants, then adaptability to different unit types is improved, but manufacturing complexity increases
Solution Approach 1:
The base body incorporates a dynamic spring element with adjustable stiffness characteristics that can adapt to different touch control unit types. The spring element is designed to provide appropriate mounting forces for both first type (lower weight) and second type (higher weight) touch control units through its inherent elastic properties, eliminating the need for multiple specialized mounting structures and simplifying manufacturing while maintaining adaptability
Solution Approach 2:
The spring constant of the mounting system is optimized to accommodate different touch control unit weights and requirements. By designing the spring element with specific stiffness parameters that can handle both lighter first type units and heavier second type units, the system achieves versatility without requiring complex manufacturing processes or multiple component variants
3Quantity of substance
If a standardized base body is used for all touch control units, then storage costs are reduced, but mounting precision for different unit types may be compromised
Solution Approach 1:
While the base body maintains a standardized overall structure for efficient storage and handling, it incorporates localized adaptive features such as adjustable spring elements and configurable mounting positions that can be optimized for specific touch control unit types during assembly. This allows a single standardized base body design to be used across different unit types while still achieving precise mounting for each specific configuration
