Awning Arm Asymmetrical Profiles Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulated arms for awnings lack structural improvements for compactness and safety, particularly in terms of space optimization and risk of tensioning means breakage during assembly and transport, which can lead to injuries.
Innovation Solution
The articulated arm features asymmetrical profiles with a convex and concave design, incorporating a spring, flexible strip, hook, and bolt tensioning means, along with metallic safety covers and trims to prevent component ejection and enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional symmetrical profiles are used for articulated arms, then the structure is simple to manufacture, but the arm cannot compact effectively in the closed position and occupies excessive space
Solution Approach 1:
The patent applies asymmetry by designing the articulated arm with non-symmetrical profiles where one profile has a convex shape and the other has a concave shape. This asymmetric configuration allows the profiles to nest within each other when the arm is in the closed position, significantly reducing the space occupied by the arm while maintaining structural integrity and functionality.
2Reliability
If plastic covers are used for safety protection, then the manufacturing cost is reduced, but the covers deteriorate quickly and fail to prevent component ejection effectively
Solution Approach 1:
The patent employs composite materials by combining metallic safety covers and trims with the existing profile structure. The metallic covers provide enhanced durability, strength, and resistance to deterioration compared to plastic alternatives, while still being integrable into the overall manufacturing process. This composite approach ensures reliable protection against component ejection while maintaining reasonable manufacturing feasibility.
3Reliability
If the tensioning means are secured firmly in the arm, then the risk of breakage during handling is reduced, but the assembly complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-securing the tensioning means within the profile structure during manufacturing. The tensioning means are positioned and fixed in advance within the hollow section of the profile, ensuring they are properly secured before the product reaches the customer. This preliminary securing reduces the risk of breakage during handling and transport while minimizing assembly complexity for the end user.
