Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for portable lighting apparatuses that offer convenient adjustment, flexibility, and low cost, as traditional lighting devices are not suitable for all situations, especially during emergencies or when indoor power is disrupted.
Innovation Solution
A portable lighting apparatus comprising a top cover, bottom cover, light passing cover, battery, power circuit, power switch, and light source plate with multiple LED modules, where the light passing cover presses an elastic unit to operate the power switch, allowing for adjustable light patterns and potential connectivity with other units, along with a clock unit for wake-up light functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable lighting apparatus is designed with adjustable light patterns and connectivity features, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The lighting apparatus is divided into modular components including a light source plate with multiple LED modules, a separate power circuit board, and a control unit. This segmentation allows each module to be independently optimized and assembled, reducing overall device complexity while maintaining versatility through modular reconfiguration for different light patterns and connectivity configurations.
2Adaptability or versatility
If traditional lighting devices are used, then device complexity is low, but adaptability and convenience for various situations deteriorates
Solution Approach 1:
The lighting apparatus integrates multiple functions into a single device including illumination, adjustable light patterns for different moods or situations, wake-up light functionality with gradual brightness increase, and wireless connectivity for remote control. This multi-functionality allows the device to adapt to various situations such as emergency lighting, ambient illumination, and alarm scenarios without requiring multiple separate devices.
3Use of energy by moving object
If LED modules are used for illumination, then energy efficiency and lifespan are improved, but initial cost increases
Solution Approach 1:
The patent employs standard commercial LED modules that are mass-produced and relatively inexpensive, rather than custom-engineered high-performance LEDs. These conventional LED modules provide sufficient energy efficiency and lifespan for portable lighting applications while keeping the bill of materials cost manageable for mass-market pricing.
4Ease of operation
If a power switch mechanism is integrated into the lighting apparatus, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The power switch mechanism replaces traditional mechanical switches or buttons with a capacitive touch-sensitive surface integrated into the housing. This electronic sensing approach eliminates moving parts, reduces mechanical complexity, and provides intuitive operation where users simply tap the surface to toggle power or adjust settings.
