Solution Overview

Problem

Existing illumination devices for outdoor activities, such as camping, often require intrusive fasteners or deformation of the object to be attached, and lack versatile and weather-resistant designs.

Innovation Solution

A selectively attachable illumination device with a flexible body and magnetic components that magnetically couple to objects like canvas chairs and tents, allowing secure attachment without deformation and featuring weather-resistant materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If intrusive fasteners are used to attach illumination devices, then secure attachment is achieved, but the object structure is damaged or deformed

Engineering Contradiction:

Improveattachment strengthVSAvoidobject deformation

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with a magnetic field-based attachment system. The illumination device contains magnetic components that attract to ferromagnetic materials in the target object, providing secure attachment without mechanical intrusion or deformation. This substitution of mechanical forces with magnetic forces resolves the contradiction between attachment strength and object integrity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic field interaction as an intermediary mechanism between the illumination device and the target object. Instead of direct mechanical contact that causes deformation, the magnetic field acts as a mediator to transmit attachment forces through the object material, maintaining structural integrity while achieving secure fastening.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If traditional fastening methods are used, then secure attachment is achieved, but versatility across different objects is reduced

Engineering Contradiction:

Improveattachment strengthVSAvoidobject compatibility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent designs the illumination device with universal magnetic attachment capability that works across multiple object types (chairs, tents, tarps, canopies). The magnetic system can attach to any ferromagnetic material, making the device versatile and adaptable to various outdoor equipment without requiring object-specific fastening mechanisms, thus resolving the contradiction between attachment strength and versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs a dynamic attachment system where the magnetic force can be easily engaged and disengaged, allowing the illumination device to be quickly attached to and removed from different objects. This dynamic capability provides both secure attachment when needed and easy reconfigurability for different applications, resolving the contradiction between strong attachment and versatility.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If rigid connection methods are used, then structural stability is achieved, but ease of attachment and detachment is reduced

Engineering Contradiction:

Improvestructural stabilityVSAvoidattachment ease

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent replaces rigid mechanical connection systems with magnetic attachment, which provides stable holding force through magnetic attraction while allowing easy engagement and disengagement. The magnetic force maintains structural stability during use but can be easily overcome by simple pulling motion, resolving the contradiction between stability and ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes the property of magnetic force parameters - the attraction strength is sufficient to maintain stable attachment during normal use but can be easily overcome with minimal force for detachment. This parameter characteristic of magnetic interaction provides both structural stability and operational ease, resolving the contradiction between these two requirements.

Inventive Principle:

Principle #35Parameter changes
