CFRP Beam Member Weight Reduction in Component Mounting Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting machines face limitations in weight reduction of the X beam, high-speed movement, and increased manufacturing costs due to the complexity and processing difficulties of carbon fiber reinforced plastic (CFRP) or aramid fiber reinforced plastic (AFRP) components.
Innovation Solution
The component mounting machine employs a beam member made of CFRP or AFRP in a rectangular tubular shape, bridged between linear guides, allowing for weight reduction while maintaining rigidity and facilitating high-speed movement, and simplifying processing to reduce manufacturing costs.

Engineering Contradiction Analysis
1Weight of moving object
If the beam member is made of carbon fiber reinforced plastic or aramid fiber reinforced plastic, then weight reduction is achieved, but processing difficulty increases and manufacturing cost increases
Solution Approach 1:
The invention changes the geometric parameters of the beam member by adopting a rectangular tubular shape with specific dimension ratios. This parameter optimization allows the beam to achieve maximum structural efficiency with minimum material, reducing weight while maintaining processability of composite materials.
Solution Approach 2:
The invention utilizes carbon fiber reinforced plastic or aramid fiber reinforced plastic as the beam material. These composite materials provide high strength-to-weight ratio, enabling weight reduction while maintaining structural integrity. The simple rectangular tubular geometry is specifically chosen to be compatible with composite material manufacturing processes.
2Weight of moving object
If the beam member is made of carbon fiber reinforced plastic or aramid fiber reinforced plastic, then weight reduction is achieved, but manufacturing cost increases
Solution Approach 1:
The invention optimizes the geometric parameters of the beam member by adopting a rectangular tubular shape with specific dimension ratios. This parameter optimization allows the beam to achieve maximum structural efficiency with minimum material, reducing both weight and material cost.
Solution Approach 2:
The invention employs a simple rectangular tubular shape that can be manufactured using cost-effective composite material processing techniques. The design prioritizes manufacturing simplicity over complex geometries, reducing overall manufacturing cost despite using advanced composite materials.
3Ease of manufacture
If the beam member has a simple shape, then manufacturing cost is reduced, but rigidity may be compromised
Solution Approach 1:
The invention carefully optimizes the geometric parameters of the rectangular tubular shape, including wall thickness, outer dimensions, and length-to-diameter ratios. These parameter adjustments ensure that the simple shape provides sufficient rigidity for high-speed movement while maintaining manufacturing simplicity and cost-effectiveness.
