Solution Overview

Problem

Existing insect bite heaters lack versatility in application, particularly in low-light conditions, and are not designed for compactness and efficient energy use.

Innovation Solution

A multifunctional device with a heating plate and independently activatable light source, allowing separate use of heating and lighting functions, and a compact design with optimized component placement to maximize energy storage and reduce thermal coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a light source is added to illuminate the treatment area, then visibility in dark environments is improved, but device complexity increases

Engineering Contradiction:
Improvevisibility in dark environmentsVSAvoiddevice complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent combines the light source and heating plate into a single integrated device housing. The control unit merges the control functions for both heating and lighting into one system, allowing simultaneous or independent operation. This integration reduces the number of separate devices needed and simplifies the overall system architecture while providing both thermal treatment and illumination capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device is designed with multi-functionality, serving both as a heat treatment device for insect bites and as a flashlight for illumination. The control unit enables the device to switch between heating mode, lighting mode, or both simultaneously, making it a universal tool that addresses multiple needs (treatment and visibility) in a single device, thereby reducing device complexity compared to carrying separate devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If the light source is directly connected to the heating plate, then device complexity is reduced, but the light source cannot be activated independently

Engineering Contradiction:
Improvedevice complexityVSAvoidindependent activation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The control unit introduces dynamic control capabilities, allowing the heating plate and light source to operate independently or simultaneously based on user needs. The system can switch between different operational states: heating only, lighting only, or both together. This dynamic control architecture maintains relatively simple device structure while achieving high versatility through software-controlled flexibility.

Inventive Principle:
Principle #15Dynamics

3Illumination intensity

If the light source has high luminosity to illuminate a larger area, then illumination coverage is improved, but energy consumption increases

Engineering Contradiction:
Improveillumination coverage areaVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The control unit enables periodic or intermittent operation of the light source, allowing it to be activated only when needed for illumination rather than continuously. This periodic action pattern reduces overall energy consumption while maintaining high illumination coverage capability when the light is active. The system can switch between lighting and heating modes or operate them alternately to optimize energy usage.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The device provides excessive illumination capability (high luminosity) when needed, but uses it partially rather than continuously. The control unit allows the user to activate the high-power light source only for the specific duration and intensity required for the task, rather than operating at full capacity constantly. This partial usage of the excessive capability reduces energy consumption while maintaining the ability to provide broad illumination coverage when necessary.

Inventive Principle:
Principle #16Partial or excessive action
