Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in facilitating the transport and assembly of Ridelle enhancements, which are large and prone to damage due to their size, while maintaining mechanical integrity and appearance consistency with existing structures.
Innovation Solution
A modular framework comprising profiled parts with circular sections and longitudinal ribs, allowing for easy assembly with screws, and accommodating filling panels like grids or plates, ensuring rigidity and ease of transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the Ridelle enhancement is made as a large single part, then it provides sufficient structural integrity and appearance, but it becomes difficult to transport and prone to damage
Solution Approach 1:
The Ridelle enhancement frame is divided into multiple profiled parts (at least four profiled parts forming rectangular angles) that can be separately transported and assembled on-site. This segmentation allows compact packaging and easier handling while maintaining the overall structural integrity when assembled together with screws at each angle.
2Ease of operation
If the Ridelle enhancement is divided into several small parts, then it becomes easier to transport, but the assembly complexity increases and mechanical characteristics may be compromised
Solution Approach 1:
The connection elements (screws) are extracted as separate components from the frame structure itself. Each profiled part has built-in passages that guide and accommodate the screws, allowing for simple assembly by inserting screws through the passages without requiring additional intermediate connection parts or complex assembly procedures.
3Strength
If intermediate parts are used to connect profiled parts, then the assembly may be more robust, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The connection function is merged directly into the profiled parts themselves through the integration of passages within the profile structure. The passages are formed as part of the profiled parts during manufacturing, eliminating the need for separate intermediate connection components. The screws pass through these integrated passages to directly connect the profiled parts, simplifying the overall assembly.
4Strength
If the profiled parts are made with complex internal structures to ensure rigidity, then the mechanical characteristics improve, but the manufacturing cost increases
Solution Approach 1:
All profiled parts are designed with the same transverse profile, making them universal components that can be manufactured using the same mold or manufacturing process. This universality reduces manufacturing complexity and cost while maintaining consistent mechanical properties across all frame components. The same profile design serves multiple functions: structural integrity, rigidity, and integration of passage features.

AI summary
This frame comprises four assembled profiled pieces (2, 4, 6, 6'). Each profiled piece (2, 4, 6, 6') has a tubular section (18) and two parallel longitudinal ribs (20) extending from the tubular section (18). Within the tubular section (18) of at least two profiled pieces is a housing (30) with a circular cross-section. The profiled pieces have transverse end faces. At each corner, at least one end of a profiled part is machined such that the longitudinal ribs (20) of at least one profiled part are shortened, and a screw (16) can engage in the generally circular recess (30) of one profiled part by passing through the tubular zone (18) of the other profiled part, the longitudinal ribs (20) of one profiled part being coplanar with the longitudinal ribs (20) of the other profiled part. A riser incorporating such a frame.
