Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems face challenges in being easily producible, stable, and cost-effective, with components often requiring complex manufacturing steps and being difficult to assemble and disassemble, especially when worn parts need replacement.
Innovation Solution
The introduction of a reducing sleeve and pipe connector designs featuring latching devices with springs and cylindrical or circular ring latching lugs, allowing for quick installation and removal without additional manufacturing steps, and a two-part pipe connector design with a metal core sleeve for stability and ease of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional scaffolding components are used, then structural stability is achieved, but assembly and disassembly require complex manufacturing steps and are difficult to perform
Solution Approach 1:
The reducing sleeve is divided into functional segments: a body portion for structural support and locking lugs for connection. This segmentation allows the locking lugs to be independently designed as spring-loaded elements that can engage with scaffold components through simple insertion, eliminating complex manufacturing steps while maintaining stability.
Solution Approach 2:
The locking lugs are designed with spring-loaded mechanisms that automatically engage with the scaffold component's holes upon insertion. The springs provide automatic locking action without requiring additional fastening steps, tools, or complex assembly procedures, enabling workers to quickly assemble and disassemble the scaffolding system.
2Ease of repair
If traditional connection methods are used, then structural stability is achieved, but worn parts are difficult and costly to replace
Solution Approach 1:
The reducing sleeve is designed as a modular component where the body and locking lugs are integrated but functionally separable. When wear occurs, the entire reducing sleeve can be quickly removed from the scaffold component by releasing the spring-loaded locking lugs, and replaced with a new unit without affecting the underlying scaffold structure or requiring complex disassembly procedures.
Solution Approach 2:
The reducing sleeve is designed as a consumable component with a defined service life. When worn, it is replaced rather than repaired, similar to disposable components in other industries. This approach reduces maintenance complexity and downtime, as workers simply remove the worn reducing sleeve and install a new one without needing specialized repair tools or procedures.
3Weight of moving object
If lightweight materials are used for scaffolding, then ease of assembly is improved, but structural stability may be compromised
Solution Approach 1:
The reducing sleeve employs composite construction combining plastic material for the body (providing lightweight properties) with metal locking lugs (providing high-strength connection). This composite approach allows the main body to remain lightweight for easy handling while the metal locking lugs ensure stable, reliable engagement with the scaffold components, achieving both weight reduction and structural stability.

Function Achieved in This Case
Enables the rapid assembly and disassembly of scaffolding components, ensuring stability and cost-effectiveness, with the ability to easily replace worn parts, thus improving the efficiency and longevity of scaffolding systems.
Implementation Method 1
the locking lug projects outwards beyond the outer surface in a locking position and is spring-loaded on the sleeve body such that it can be pressed into the sleeve body from the locking position against a restoring force of the spring
