Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-defense weapons are often bulky, difficult to conceal, and lack innovative designs for effective use against attackers.
Innovation Solution
A lightweight self-defense whip with a handle and flexible cord system, featuring annular weights and a catch mechanism to prevent weight movement, providing a portable and efficient means of self-defense.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional self-defense weapons are used, then effectiveness against attackers is improved, but portability and concealability deteriorate due to bulkiness
Solution Approach 1:
The self-defense weapon is segmented into distinct components: a flexible cord with multiple annular weights spaced along its length, allowing the weapon to be divided into functional segments that can be independently positioned during use while remaining compact when stored
Solution Approach 2:
The annular weights are designed to nest along the flexible cord, with each weight capable of sliding to specific positions. When not in use, the weights can be positioned close together along the cord, creating a compact nested configuration that fits within a small handle, similar to nested dolls

Solution Approach 2:
The flexible cord allows the annular weights to dynamically change position during use, extending outward to create an effective defensive arc. The cord's flexibility enables the weapon to adapt its shape and volume from a compact stored state to an expanded operational state
3Weight of moving object
If lightweight and portable design is implemented, then portability is improved, but structural stability and weight distribution deteriorate
Solution Approach 1:
Rather than making the entire weapon lightweight, the invention uses a lightweight flexible cord and handle but incorporates dense annular weights at specific locations along the cord. This local quality approach provides concentrated mass for effective impact while keeping the overall structure lightweight and portable
Solution Approach 2:
The annular weights are pre-positioned at specific intervals along the flexible cord during manufacturing, creating optimal weight distribution before use. This preliminary arrangement ensures proper balance and weight distribution is achieved without requiring complex adjustment mechanisms during operation

AI summary
A self-defense whip for protecting against would-be attackers and serving as an alternative to other available means of self-defense includes a handle having a first end and a second end. A flexible cord has a proximate end relative to the handle and a distal end relative to the handle, the proximate end of the flexible cord being coupled to the second end of the handle. Each of a plurality of annular weights receives therethrough the flexible cord proximate the distal end of the flexible cord. A catch is coupled to the distal end of the cable and has a width greater than an inner diameter of each annular weight wherein the catch is configured to prevent each annular weight from moving past the distal end of the flexible cord.
