Two-Piece Cam Lever Accessory Lock for Tool-Free Pole Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for securing accessories to vertical poles require tools and often use sleeves or wedges, which can be inconvenient and limiting in terms of versatility and ease of use.
Innovation Solution
A two-piece accessory lock system that interlocks around a vertical pole without the need for tools, utilizing a cam lever and tension device to secure shelves, hooks, and other accessories, with optional features like integral hooks and removable brackets for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional devices with sleeves or wedges are used to secure accessories to vertical poles, then the attachment is secure and reliable, but the installation requires tools and is time-consuming
Solution Approach 1:
The accessory lock is divided into two separable pieces (first piece and second piece) that can be independently positioned and then interlocked together around the pole, enabling tool-free assembly while maintaining secure attachment
Solution Approach 2:
The lever mechanism transforms rotational motion into linear clamping force, dynamically adjusting the tension between the two pieces to securely grip the pole without requiring tools for installation
2Adaptability or versatility
If sleeves or wedges are used to secure accessories, then the attachment mechanism is simple, but the versatility for different accessories is limited
Solution Approach 1:
The accessory lock design with two interlocking pieces and a lever mechanism creates a universal attachment system that can accommodate various accessories (shelves, hooks, bins, mirrors) on different pole diameters without requiring accessory-specific hardware
Solution Approach 2:
The two pieces of the accessory lock nest together around the pole, with one piece fitting inside or alongside the other, creating a compact and adaptable structure that can adjust to different pole sizes while maintaining a simple overall form
3Productivity
If traditional attachment methods are used, then the components are simple in design, but the installation time is excessive
Solution Approach 1:
The two pieces of the accessory lock are designed to be pre-positioned around the pole before final tightening, allowing for quick alignment and rapid installation without requiring complex tool-based assembly procedures
Solution Approach 2:
The lever mechanism enables rapid transformation from an open to a closed clamping position through simple rotational motion, dramatically reducing installation time compared to traditional tool-based tightening methods
