Tail Attachment Shackle Rod Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tail attachment methods for role-play costumes, such as those in the furry subculture, face issues with secure and easy detachment, as they often rely on glued connections that are prone to inadvertent detachment and lack durability.
Innovation Solution
A tail assembly that uses a bodily insertion device with a shackle and rod system, where the rod is inserted through an eyelet in the tail and secured between spaced arms of the shackle, providing a strong and mechanical coupling that allows for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If glued connections are used to attach the tail to the bodily insertion device, then the attachment process is simple, but the connection strength and reliability are insufficient and prone to inadvertent detachment
Solution Approach 1:
The attachment system is divided into separate components: a shackle with spaced arms attached to the bodily insertion device, and a tail with an eyelet. These segments are connected through a rod that passes through both components, allowing for modular assembly and disassembly while maintaining strong connection.
Solution Approach 2:
A rod serves as an intermediary element that connects the shackle and the tail. The rod passes through the spaced arms of the shackle and the eyelet of the tail, creating a mechanical linkage that provides both ease of attachment and strong connection strength.
2Device complexity
If glued connections are used to attach the tail, then the device structure is simple, but the durability and resistance to pulling forces are insufficient
Solution Approach 1:
The attachment system allows for dynamic assembly and disassembly through the rod mechanism. The rod can be easily inserted and removed from the spaced arms and eyelet, providing both structural integrity during use and ease of removal when needed, thus balancing complexity with strength requirements.
Solution Approach 2:
The shackle features asymmetric spaced arms that are positioned to receive the rod, creating a configuration where the tail is securely held in place during normal use but can be easily removed by applying force in the opposite direction, thus achieving both strength and ease of detachment.
3Reliability
If a mechanical shackle and rod system is used instead of glued connections, then the connection strength and reliability are improved, but the device complexity increases
Solution Approach 1:
The shackle with spaced arms serves multiple functions: it provides structural support for the tail attachment, acts as a mounting interface for the rod, and enables easy assembly and disassembly. This multi-functionality reduces the need for additional components, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The rod is nested within the spaced arms of the shackle and passes through the eyelet of the tail, creating a compact nested structure. This nesting arrangement minimizes the space required for the attachment mechanism and reduces the number of separate components needed, thus limiting the increase in device complexity.

AI summary
An example tail assembly includes a bodily insertion device that extends along a longitudinal axis from a base to a tip. A shackle is secured to the base and includes a pair of spaced apart arms. The example tail assembly also includes a tail having an eyelet, and a rod inserted into respective openings in the spaced apart arms. The rod is inserted through the eyelet between the respective openings, thereby securing the tail to the bodily insertion device. A method of securing a tail to a bodily insertion device is also disclosed.
