Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing members for electronic components in high-voltage electrical equipment, such as those in electric or hybrid vehicles, can cause damage due to excessive force exerted on the components' surfaces, and existing solutions complicate assembly and increase height.
Innovation Solution
A pressing member with a plate-shaped portion and leaf springs where all edges of through-openings are formed by leaf springs, distributing force more evenly and reducing the risk of surface damage, allowing for a more efficient and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a pressing member with spring blades is used to clamp electronic components against a cooling system surface, then effective cooling is achieved through improved thermal contact, but the surface of the electronic component can be damaged due to excessive force from individual spring blades
Solution Approach 1:
The pressing member is segmented into multiple spring blades (at least three) that are distributed around a through-opening. This segmentation allows the total clamping force to be divided into multiple smaller contact points, reducing the force concentration on any single point of the electronic component surface while maintaining overall effective cooling contact.
Solution Approach 2:
The spring blades are positioned to contact specific local areas of the electronic component surface rather than applying uniform pressure across the entire surface. This localized contact approach ensures adequate thermal contact for cooling while avoiding excessive force on any single vulnerable surface area.
2Object-affected harmful factors
If a second plate is introduced between the electronic component and the pressing member to distribute force, then surface damage is prevented, but the height of the assembly increases and assembly becomes more complex
Solution Approach 1:
The function of force distribution is merged directly into the pressing member structure itself through the through-opening design with spring blades. Instead of requiring a separate force-distributing plate, the pressing member's own geometry (the through-opening surrounded by spring blades) performs both the clamping and force distribution functions simultaneously, reducing assembly complexity and overall height.
Solution Approach 2:
The pressing member with the through-opening configuration serves multiple functions: it provides the clamping force necessary for cooling contact, distributes that force to prevent surface damage, and maintains structural integrity. This multi-functional design eliminates the need for separate dedicated force-distributing components.
3Object-affected harmful factors
If multiple spring blades are used to distribute pressing force, then surface damage is reduced, but the structure becomes more complex
Solution Approach 1:
The pressing member is segmented into multiple spring blades that are naturally formed by cutting or shaping the plate material around a through-opening. This segmentation achieves force distribution while maintaining a relatively simple overall structure that can be manufactured as a single piece, minimizing structural complexity.
