Rigid Telescopic Protective Cover With Integrated Return Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective covers for machine tools are expensive to produce and heavy due to the need for additional resilient reset elements and complex attachments, which compromise sealing effectiveness and increase weight, making them difficult to process at high speeds.
Innovation Solution
A protective cover design featuring L-shaped segments with a self-rigid, tape-like connecting element that integrates elastic functionality, eliminating the need for separate reset elements and their attachments, providing a secure and dense closure through intrinsic bending stiffness and torque transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate resilient reset elements and their attachments are added to ensure dense closure, then sealing effectiveness is improved, but production cost and weight increase
Solution Approach 1:
The patent combines the resilient reset element function directly into the connecting element that joins protective cover segments. The connecting element itself is made elastically deformable, eliminating the need for separate reset elements and their attachments. This merging reduces production cost and device complexity while maintaining sealing effectiveness through the inherent elasticity of the connecting element.
2Reliability
If separate resilient reset elements and their attachments are added to ensure dense closure, then sealing effectiveness is improved, but weight increases
Solution Approach 1:
The resilient reset function is merged into the connecting element, which is already present in the structure to join protective cover segments. By making the connecting element itself elastically deformable rather than adding separate reset elements, the patent eliminates additional weight while maintaining sealing effectiveness through the connecting element's inherent elasticity.
3Reliability
If additional reset elements and attachments are added, then dense closure is achieved, but manufacturing and assembly effort increase
Solution Approach 1:
The patent merges the resilient reset function into the connecting element, which is an existing structural component. This eliminates the need for separate reset elements and their attachments, significantly reducing manufacturing and assembly effort. The connecting element is designed to be elastically deformable, providing dense closure through its inherent properties without requiring additional manufacturing steps or assembly operations.
4Reliability
If additional reset elements and attachments are added, then dense closure is achieved, but block dimension increases when pushed together
Solution Approach 1:
The resilient reset function is integrated into the connecting element, which is already part of the telescopic structure. This eliminates the need for separate reset elements that would add to the block dimension when the cover is pushed together. The connecting element's elasticity provides dense closure without increasing the compacted length of the protective cover.
5Reliability
If additional reset elements and attachments are added, then dense closure is achieved, but the protective cover becomes more expensive to produce
Solution Approach 1:
The patent merges the resilient reset function into the connecting element, which is an existing structural component. This eliminates the need for separate reset elements and their attachments, reducing the number of parts, materials, and manufacturing steps required. The connecting element is designed to be elastically deformable, providing dense closure through its inherent properties, which simplifies production and reduces costs.
