Reinforcement Ring for Electromechanical Actuator Housing Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromechanical actuator (EMA) housing designs suffer from deflection issues that lead to inaccurate load cell measurements and reduced braking response time, necessitating re-trimming and increased weight due to the use of thick steel washers for stabilization.
Innovation Solution
Incorporating a reinforcement ring within the EMA housing assembly that decreases axial distance towards the centerline, reducing material usage and eliminating the need for thick washers, while maintaining or slightly increasing the housing's stiffness and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If thick steel washers are used for stabilization, then housing stability is improved, but weight increases
Solution Approach 1:
The patent removes the thick steel washers from the housing assembly and replaces them with a reinforcement ring integrated into the housing structure. This extraction of the separate washer component eliminates the weight penalty while maintaining stability through the integrated ring design.
Solution Approach 2:
The reinforcement ring is integrated directly into the housing structure, merging the stabilization function with the housing itself. This integration eliminates the need for separate thick steel washers, reducing overall weight while maintaining structural stability.
2Ease of manufacture
If conventional housing design is used, then manufacturing is simpler, but deflection occurs leading to measurement inaccuracy
Solution Approach 1:
The reinforcement ring is strategically positioned at the top of the housing where deflection occurs, providing localized structural support. This allows the rest of the housing to remain simple for easy manufacturing, while the specific area prone to deflection receives enhanced support to maintain measurement accuracy.
3Measurement precision
If reinforcement ring is added, then deflection is reduced, but manufacturing complexity increases
Solution Approach 1:
The reinforcement ring utilizes a composite structure combining aluminum housing material with strategic reinforcement elements. This composite approach provides the necessary stiffness to reduce deflection and improve measurement accuracy while keeping the overall design manageable and not excessively complex.
4Weight of moving object
If material usage is reduced, then weight decreases, but structural strength may be compromised
Solution Approach 1:
The reinforcement ring changes the structural parameters of the housing by introducing a geometric feature that increases stiffness without proportionally increasing material volume. The ring's shape and positioning are optimized to provide maximum structural benefit with minimal material addition, maintaining strength while controlling weight.
