Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforced supports for building applications suffer from deformation due to hammer blows during disassembly, require complex machining processes, and incur high costs due to mechanical stress on materials and the need for multiple tools, while also posing safety risks with sharp ends.
Innovation Solution
A reinforced support design featuring an outer tubular element with a lower portion having unevenness in the form of transverse, longitudinally offset circular rings for impact resistance, machined using a single tool to minimize mechanical stress and prevent deformation, allowing for efficient and safe disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If continuous axial profiling is used to reinforce the outer tubular element, then impact resistance is improved, but mechanical stress on the material increases and original mechanical characteristics are considerably changed
Solution Approach 1:
The continuous axial profiling is segmented into discrete circumferential rings with projections. Instead of a continuous corrugated profile extending along the entire length, the reinforcement is divided into separate ring structures spaced apart axially. This segmentation reduces cumulative mechanical stress on the material while maintaining impact resistance at the reinforced locations.
Solution Approach 2:
The reinforcement is applied locally at specific circumferential positions rather than continuously along the entire tubular element. The projections are formed at discrete locations around the circumference, providing localized impact resistance where needed while preserving the original mechanical characteristics of the material in non-reinforced areas.
2Strength
If continuous axial profiling with two different tools is used for machining, then impact resistance is improved, but machining costs and time increase
Solution Approach 1:
The machining process merges the functions of two different tools into a single tool. The single tool is designed to both radially deform the inner surface and form the circumferential rings with projections, eliminating the need for separate machining operations and reducing overall machining time and cost.
Solution Approach 2:
The single machining tool is given multi-functionality to perform both the radial deformation of the inner surface and the formation of the circumferential reinforcement rings. This universal tool approach simplifies the manufacturing process and improves productivity by reducing the number of tool changes and setup operations.
3Strength
If axial projections with pointed and sharp ends are used for reinforcement, then impact resistance is improved, but operator safety is compromised due to injury risk
Solution Approach 1:
The pointed and sharp ends of the axial projections are replaced with rounded or curved surfaces. The projections maintain their reinforcing function through their circumferential arrangement and radial deformation capability, while the rounded geometry eliminates the hazard of sharp points that could injure operators during handling or installation.
4Strength
If axial profiling is used for reinforcement, then impact resistance is improved, but the reinforcing portion does not uniformly distribute the impact along the entire extent of the support
Solution Approach 1:
The reinforcement pattern transitions from continuous axial symmetry to a distributed circumferential pattern with discrete rings. The circumferential rings with multiple projections around the circumference create a more uniform distribution of impact forces across different angular positions, preventing concentration of stress at specific axial locations.
