Protective Coat Rack With Strobe and Alarm Attack Deterrence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preventive measures against bladed weapon assaults require personal commitment and regular training, lacking an easy and discreet security solution for emergency situations.
Innovation Solution
A coat rack transformed into a self-defense tool with a pole end supporting branches and emitting sources for signals, including sound and light, which can be activated to deter attackers without training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-defense techniques and training are used to prevent bladed weapon assaults, then protection effectiveness is improved, but the requirement for personal commitment and regular practice increases complexity and accessibility barriers
Solution Approach 1:
The coat rack automatically activates protective functions (sound alarm, light emission) when subjected to aggressive forces, eliminating the need for user training or deliberate action. The system serves itself by detecting the attack through the pole's displacement and immediately deploying deterrent mechanisms.
Solution Approach 2:
The coat rack is pre-configured with emitting sources and control mechanisms that are activated in advance upon detection of aggressive force. The system prepares the protective response beforehand, so when an attack occurs, the alarm and light are immediately deployed without requiring the user to initiate them.
2Reliability
If a coat rack is transformed into an anti-aggression tool with emitting sources, then protection capability is improved, but device complexity increases
Solution Approach 1:
The coat rack serves dual functions: it maintains its traditional role as a clothing storage device while simultaneously functioning as a self-defense system with sound and light emitting capabilities. This multi-functionality allows the protective system to be integrated into everyday objects without requiring separate dedicated security devices.
Solution Approach 2:
The patent combines the coat rack structure with emitting sources (sound and light) and control mechanisms into a single integrated system. The pole, base, and emitting components are merged into one cohesive unit that operates automatically when subjected to aggressive forces.
3Reliability
If the pole length is increased to maintain safe distance from aggressor, then protection effectiveness is improved, but the risk of causing serious injury to the attacker increases
Solution Approach 1:
The patent converts the potential harm of a long pole (which could cause serious injury) into a beneficial protective effect by combining it with non-lethal emitting sources. The sound and light emissions serve as primary deterrents that protect the user without requiring physical contact that could inflict serious injury on the attacker.
Solution Approach 2:
The emitting sources (sound and light) act as intermediaries between the user and the attacker. Instead of direct physical confrontation that could cause serious injury, the system uses acoustic and optical mediators to deter the attacker and alert others, reducing the need for forceful physical intervention.

AI summary
The present invention relates to a coat rack comprising a pole (1) one end (2) of which is removably inserted into a base and the other end (3) of which supports a plurality of branches (4) forming hooks. The coat rack further comprises at least one emitting source (6, 7) housed in the free end (3) of the pole (1) and capable of emitting a signal of frequency and intensity suitable for disrupting an attacker on command via control means (8) of the emitting source (6, 7).
