Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control units (ECUs) require complete replacement when components are upgraded, leading to increased material usage and costs, as well as heat management issues due to the need for maintaining heat sink structures.
Innovation Solution
A removable heat transfer adapter with a body having a base surface for contacting the housing and pedestals for contacting electronic components on a printed circuit board, allowing for the upgrade or replacement of components while maintaining heat dissipation through the housing or associated heat sink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complete ECU replacement is performed when components need upgrading, then electronic component upgrades are achieved, but material usage increases and costs increase
Solution Approach 1:
The ECU is divided into separable modules: a reusable housing containing the heat sink, and a replaceable adapter assembly containing the PCB and electronic components. This segmentation allows upgrading only the necessary components while retaining the housing and heat sink structure, thereby reducing material waste.
Solution Approach 2:
The housing and heat sink structures are recovered and reused across multiple component upgrades, while only the adapter and electronic components are discarded and replaced. This recovery approach directly addresses the material usage problem by preventing unnecessary disposal of durable structural elements.
2Adaptability or versatility
If complete ECU replacement is performed when components need upgrading, then electronic component upgrades are achieved, but manufacturing costs increase
Solution Approach 1:
By segmenting the ECU into reusable housing and replaceable adapter assemblies, manufacturing costs are reduced because the expensive housing and heat sink structures are manufactured once and reused, rather than being manufactured with every component upgrade.
Solution Approach 2:
The housing and heat sink structures serve as universal components that can accommodate multiple different adapter assemblies with various electronic components. This multi-functionality allows a single housing design to support multiple product generations, reducing per-unit manufacturing costs.
3Temperature
If heat sink structures need to be maintained after component upgrades, then heat dissipation function is preserved, but device complexity increases
Solution Approach 1:
The heat sink function is merged with the reusable housing structure, creating an integrated thermal management solution. This eliminates the need for separate heat sink maintenance operations, as the housing itself serves as the heat dissipation structure throughout the ECU's lifecycle.
Solution Approach 2:
The adapter assembly acts as an intermediary thermal interface between the electronic components and the housing heat sink. This intermediary design allows heat transfer while maintaining the simplicity of the housing structure, as the adapter handles component-specific thermal requirements without requiring housing modifications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the substitution and upgrade of electronic components within the ECU, minimizing material usage and reducing costs by allowing the adapter to be easily removed and reinstalled, while maintaining effective heat transfer and reducing the need for new aluminum usage.
Implementation Method 1
The adapter provides an interface between the PCB and a wall of the ECU housing that functions as a bridge for heat transfer, so that the heat dissipating function of the housing or an associated heat sink can be maintained
