Marking and Fastening Device with Ratchet System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices lack the ability to both mark and securely attach to materials without permanent attachment methods, leading to inefficiencies and errors in positioning, and do not allow for easy reusability or adjustability.
Innovation Solution
A marking and fastening device featuring a ratchet system with a projection and pawl mechanism that allows for detachable attachment and marking of materials, enabling secure fastening without conventional attachment means and allowing for easy repositioning and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If female sockets are permanently mounted on tarp material by riveting, then the attachment strength is improved, but the ease of repair and reusability deteriorates
Solution Approach 1:
The device is divided into separate components: a marking member with projection and a fastening member with aperture, allowing the marking function and fastening function to be separated yet coordinated. This segmentation enables the marking to be made without permanently attaching the fastening elements to the material.
Solution Approach 2:
The projection on the marking member performs the marking action on the material before the fastening member is permanently attached. This preliminary marking guides the subsequent permanent attachment, allowing for error correction before final commitment of the fastening elements.
2Manufacturing precision
If tarp material is secured over the object with clamps for marking, then the positioning accuracy is improved, but the labor time and complexity increase
Solution Approach 1:
The marking member itself performs the marking function by directly contacting and marking the material through its projection, eliminating the need for separate clamping devices and manual positioning operations. The device serves its own marking purpose without requiring additional securing mechanisms.
3Reliability
If female sockets are permanently secured onto tarp material, then the reliability of attachment is improved, but the adaptability deteriorates
Solution Approach 1:
The marking is performed in advance before permanent attachment, allowing the user to verify positioning accuracy and make adjustments if needed. Only after satisfactory marking and positioning is confirmed does the permanent attachment proceed, ensuring both reliability and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A fastening device and a method of using same is provided. The fastening device includes a male member having a projection on a first side and a securing means on a second opposing side. A female member configured to receive the projection detachably secures the female member onto the male member. The female member and the male member comprises a ratchet system to removeably secure the female member onto the male member. The securing means on the second opposing side of the male member is configured to mate with a corresponding securing member mounted on an object. By securing a material such as a shade screen or a tarp on the male member by mating the male member with the female member, the shade screen or tarp may be detachably fastened onto an object.
