Tool-Less Coil-Spring Attachment for Mid-Point C-Channel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching and detaching materials from c-channel grooves require tools and access to the ends of the groove, making replacement cumbersome and costly, especially in applications like solar panel cleaning robots and automotive car washes.
Innovation Solution
A coil-shaped element that is resiliently compressible and can be navigated through the c-channel groove from any point, allowing for tool-free attachment and detachment by applying a force to bias the element into the groove and then restoring it to secure within the channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods are used to attach materials to c-channel grooves, then secure attachment is achieved, but access to the ends of the groove and tools are required, making replacement cumbersome
Solution Approach 1:
The attachment system is divided into separate components: a C-channel groove structure and a独立的夹持装置 that can be independently manipulated. The夹持装置 can be attached at any position along the channel without requiring disassembly of the entire structure or access to endpoints, enabling modular and flexible maintenance operations.
Solution Approach 2:
The夹持装置 is designed to be self-contained with integrated gripping elements that automatically secure the channel when positioned. The device uses its own structural features (such as spring-loaded clips or snap-fit mechanisms) to achieve attachment without external tools or assistance, making the replacement process self-service oriented.
2Reliability
If tools are required to replace brush flaps, then secure attachment is achieved, but operating and maintenance costs increase
Solution Approach 1:
The design replaces traditional mechanical fastening systems (screws, bolts, clips requiring tools) with a tool-less mechanical engagement system. The夹持装置 uses inherent mechanical properties of the C-channel geometry combined with spring-loaded or elastic gripping elements that automatically engage and secure without requiring external tools, thereby reducing maintenance complexity and cost while maintaining reliable attachment.
3Stability of the object's composition
If brush flaps are secured in the c-channel, then they remain in place during operation, but they cannot be easily replaced without removing entire series elements
Solution Approach 1:
The夹持装置 is designed as an independent, localized attachment mechanism that can be applied to individual positions along the C-channel. This segmentation allows each brush flap or material element to be secured and replaced independently without affecting adjacent elements, enabling rapid replacement of single components while maintaining stability during operation.
Solution Approach 2:
The夹持装置 is pre-designed with built-in securing mechanisms that automatically engage when the device is positioned on the channel. This preliminary preparation of the attachment mechanism eliminates the need for complex assembly procedures during replacement, allowing operators to quickly install or remove individual elements without dismantling the entire series structure.
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 flexible and efficient replacement of materials along the entire length of the c-channel without tools, reducing maintenance costs and allowing for easy replacement of elements in the middle of a series, particularly beneficial for large-scale applications.
Implementation Method 1
The coil-shaped element is in a biased state such that it is navigable through the aperture of the c-channel groove... The coil-shaped element restores within the channel toward the second dimension so as to secure itself within the c-channel groove

AI summary
A method and device for attaching and detaching material to a c-channel groove, including attachment and detachment between first and second objects already attached to the groove. The device comprises a coil-shaped element that is resiliently compressible and connected to a desired material. Through biasing, the coil-shaped element is navigable into an aperture of the c-channel groove at a point along the c-channel groove between the ends of the c-channel groove and positionable such that at least a portion of the biased coil-shaped element is in the c-channel groove. Upon restoring the biased coil-shaped element toward a second, larger dimension, it is secured in the c-channel groove and the material connected to the coil-shaped element is attached to the c-channel groove, including between the first object and the second object, if present.
