Battery Support Beam Internal Stabilizer Buckling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automobile battery enclosures face challenges in reducing weight while maintaining structural integrity, particularly in preventing buckling under impact due to the use of lighter materials for support members.
Innovation Solution
A support beam design featuring an internal stabilizer within a through passage at the beam end, with stabilizer sidewalls and a bridge connecting them, which is coupled to external bulkheads to resist buckling by transmitting loads along the beam's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lighter materials are used for support members to reduce weight, then the weight of the battery enclosure is reduced, but the support members may buckle under impact
Solution Approach 1:
The patent applies nesting by placing an internal stabilizer inside the support beam's hollow body. The stabilizer is positioned within the through passage of the beam, creating a nested structure where a smaller structural element is contained within a larger one. This nested configuration allows the lighter hollow beam to gain additional buckling resistance from the internal stabilizer without sacrificing the weight reduction benefits of the hollow design.
Solution Approach 2:
The patent applies composite structural design by combining the hollow beam body with an internal stabilizer to create a composite support member. The final structure integrates two different structural elements (the hollow beam and the internal stabilizer) into a unified composite component that achieves both weight reduction and enhanced buckling resistance, effectively resolving the contradiction between light weight and strength.
2Weight of moving object
If a hollow support beam is used to reduce weight, then the weight of the battery enclosure is reduced, but the structural integrity under impact is compromised
Solution Approach 1:
The hollow support beam contains an internal stabilizer nested within its through passage, creating a nested structure that enhances reliability. The internal stabilizer is positioned to provide structural support along the length of the hollow beam, ensuring that the lightweight hollow design maintains sufficient structural integrity to resist buckling under impact conditions.
Solution Approach 2:
The patent creates a composite structural system by integrating the hollow beam body with an internal stabilizer. This composite design combines the weight advantages of the hollow structure with the reliability benefits of the internal stabilizer, achieving both reduced weight and maintained structural integrity under impact loading.
3Strength
If an internal stabilizer is added to prevent buckling, then the buckling resistance of the support beam is improved, but the device complexity increases
Solution Approach 1:
The internal stabilizer is nested within the existing hollow support beam structure, utilizing the available internal space of the through passage. This nesting approach allows the buckling resistance to be improved without adding external components or significantly increasing overall structural complexity, as the stabilizer fits within the existing hollow geometry of the beam.
