Paint Roller Handle Bracket Separation for Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Color roller brackets, typically made of plastic and metal, are often discarded after use, contributing to waste and resource inefficiency, as they are difficult to recycle due to their integrated design.
Innovation Solution
A color roller bracket design where the handle and bracket can be easily separated by the user, allowing for separate recycling of plastic and metal components, featuring a pipe segment with projections to prevent rotation and a tube with clamping sections for secure attachment and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the handle and bracket are integrated into a single design, then the structural stability and simplicity are improved, but the recyclability and resource conservation are worsened
Solution Approach 1:
The paint roller handle is divided into two separate components: a handle body and a bracket, connected through a receptacle system. This segmentation allows the components to be separated for recycling while maintaining structural stability during use, directly resolving the contradiction between integrated design stability and recyclability.
2Reliability
If the handle and bracket are made of different materials (plastic and metal alloy), then the functional performance is improved, but the recyclability is worsened due to material mixing
Solution Approach 1:
The handle and bracket are designed as separable components made of different materials (plastic handle and metal alloy bracket). The segmentation enables each material to be recycled separately despite the functional benefits of using different materials for different components.
Solution Approach 2:
The design facilitates the discarding and recovering process by enabling easy separation of the plastic handle and metal bracket components. Users can manually detach the bracket from the handle, allowing each material type to be recovered and recycled independently, resolving the recyclability issue while maintaining functional performance.
3Stability of the object's composition
If the bracket is securely fixed in the holder, then the stability during use is improved, but the ease of separation for recycling is worsened
Solution Approach 1:
The connection between the bracket and holder is designed to be dynamic rather than permanent. The receptacle system allows the bracket to be securely held during use but enables easy manual separation when needed for recycling, resolving the contradiction between stability during operation and ease of separation.
Solution Approach 2:
The holder and receptacle are designed to work together in a self-service manner, where the structural design itself enables easy separation without requiring additional tools or complex mechanisms. The user can simply pull the bracket out of the holder manually, making the separation process as easy as the initial attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables sustainable reuse and recycling of the bracket and handle, reducing waste and conserving resources by allowing manual separation and recycling of the materials without tools.
Implementation Method 1
The projections of the holder surround the angled section of the bracket in a form-fitting and/or friction-fitting manner. The two projections exhibit a certain degree of elasticity. When inserting the bracket, the projections are pushed apart at least slightly. When mounted, they exert at least a slight holding force on the bracket.
Implementation Method 2
The two projections exhibit a certain degree of elasticity. When inserting the bracket, the projections are pushed apart at least slightly. When mounted, they exert at least a slight holding force on the bracket.
Implementation Method 3
The inner diameter of the clamping sections and the outer diameter of the bracket are selected such that the clamping sections are pressed outward and elastically deformed upon insertion into the receptacle. The elastic clamping sections ensure a positive and/or non-positive mounting and connection between the end section of the bracket and the receptacle.
