Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld lamps are limited in their ability to adjust light projection direction, requiring separate devices for different environments, such as flashlights for focused light and camping lamps for broader illumination, which occupy space and are inconvenient to carry.
Innovation Solution
An adjustable lamp structure featuring a case with a socket, a light penetrative shade, a scattering shade, and a reflective blade, allowing the light projecting direction to be altered by sliding the scattering shade, enabling multiple functions such as focused or wide-area illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional handheld lamps are designed for focused light projection, then light intensity in one direction is improved, but the ability to illuminate broader areas is worsened
Solution Approach 1:
The patent implements a rotatable reflective blade that can dynamically adjust its angle to change light projection direction. The reflective blade rotates around the light source, allowing the user to switch between focused forward projection and broader lateral illumination, thus resolving the contradiction between focused intensity and broad area adaptability
Solution Approach 2:
The patent creates a multi-functional lamp that can perform both focused flashlight illumination and broad camping lamp illumination using a single device. By incorporating the rotatable reflective blade, the lamp achieves universal functionality across different lighting scenarios, eliminating the need for separate devices
2Adaptability or versatility
If separate flashlight and camping lamp devices are carried, then light projection versatility is improved, but portability and convenience are worsened
Solution Approach 1:
The patent merges the functions of a flashlight and a camping lamp into a single integrated device. By combining the light source, rotatable reflective blade, and adjustable shielding mechanism in one unit, the invention achieves the versatility of multiple devices while maintaining the portability of a single handheld lamp
Solution Approach 2:
The patent creates a universal lamp that replaces multiple specialized devices. The single device can adapt to both focused task lighting and broad area illumination needs through its adjustable reflective and shielding components, improving ease of operation by eliminating the need to carry and switch between multiple lamps
3Device complexity
If a fixed light projection structure is used, then device simplicity is improved, but adaptability to different environments is worsened
Solution Approach 1:
The patent introduces dynamic adjustment capabilities through a rotatable reflective blade and a sliding shielding structure. These components allow the lamp to adapt its light projection characteristics to different environmental requirements while maintaining relatively simple mechanical implementations with few moving parts
Solution Approach 2:
The patent segments the light control function into distinct components: a reflective blade for directing light and a shielding structure for blocking light. This segmentation allows each component to perform its function independently with simple mechanics, achieving adaptability without excessive complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable lamp provides versatile light projection capabilities, allowing it to function like both a conventional flashlight and a camping lamp, reducing the need for multiple devices and enhancing usability in various environments.
Implementation Method 1
The reflective blade is located in the center of the inner side of a front end of the scattering shade, and bent inwards to reflect light at a desired angle
Implementation Method 2
The scattering shade is coupled on the periphery of the light penetrative shade and slidable thereon

AI summary
An adjustable lamp includes a lamp and a scattering shade which is slidable on the lamp. The scattering shade has a front end coupled with a reflective blade which is bent at a selected angle to reflect light. By sliding the scattering shade on a light penetrative shade, the position of the reflective blade can be changed to alter the reflective direction of the light.
