Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited installation space in electronic control systems of heating devices for motor vehicles makes it difficult to integrate filter devices directly, occupying valuable space and limiting the placement of other electronic elements.
Innovation Solution
Integrating a filter device for electric supply current filtration within the electrical adapter rather than the control unit, allowing for effective filtering of high-frequency components and current peaks while preserving space for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is integrated directly into the electronic control system, then effective filtering of supply current is achieved, but installation space for other electronic elements is reduced
Solution Approach 1:
The electrical adapter is divided into functionally independent components: signal lines for control signals, supply lines for power, and a filter device for current filtering. This segmentation allows each component to be optimized independently and arranged in space without interfering with others, resolving the contradiction between filtering effectiveness and installation space.
Solution Approach 2:
The filter device is arranged in three-dimensional space adjacent to the supply lines rather than being planarly integrated on the circuit board. This spatial reconfiguration in another dimension maintains effective filtering while preserving valuable two-dimensional installation space for other electronic elements.
2Area of stationary object
If a filter device is integrated into the electrical adapter, then installation space in the control system is preserved, but the distance from supply lines increases potentially reducing filtering effectiveness
Solution Approach 1:
The filter device is positioned locally adjacent to the supply lines at the point where filtering is most needed, rather than being centrally located in the adapter. This local placement ensures effective filtering of supply current while maintaining compact overall adapter dimensions, preserving installation space in the control system.
3Area of stationary object
If installation space is optimized by leaving out filter device space during control system construction, then more space is available for other components, but the filter device must be integrated into the adapter increasing adapter complexity
Solution Approach 1:
The filter device is merged with the electrical adapter structure, forming an integrated assembly. This combining approach consolidates multiple functions (signal transmission, power supply, and filtering) into a single adapter unit, maintaining compact overall dimensions while preserving installation space in the control system, despite increased adapter internal complexity.
