Cap-Mounted Light Emitter with Adjustable Lamp Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitters attached to caps lack adjustability in illumination direction and intensity, leading to inefficient battery usage and limited functionality, as all lamps are simultaneously turned on/off and fixedly directed forward, with no option to adjust light output based on the field being illuminated.
Innovation Solution
A light emitter with independently adjustable lamps that can be turned on/off and angled upward/downward, featuring a separate switch unit and auxiliary battery to prevent unintentional battery discharge, allowing for customizable illumination and extended battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all lamps are simultaneously turned on or off by a single switch, then the control is simple, but the ability to adjust illumination area or amount is limited and battery cannot be conserved
Solution Approach 1:
The patent divides the single switch into multiple independent switches (first switch and second switch), each controlling a specific lamp. This segmentation allows selective activation of lamps based on illumination needs, enabling adjustment of illumination area and amount while conserving battery power when not all lamps are required.
2Adaptability or versatility
If the light emitter is carried in a knapsack or pocket, then portability is improved, but the switch can be turned on unintentionally causing battery discharge
Solution Approach 1:
The patent incorporates a switch preventing mechanism that proactively prevents unintentional activation of the switch when the light emitter is carried in a knapsack or pocket. This preliminary protective measure counteracts the potential harmful action of accidental switching, thereby preventing battery discharge while maintaining portability.
3Device complexity
If all lamps are fixedly directed toward the forward direction, then the structure is simple, but the user cannot change the direction of illumination without moving the head
Solution Approach 1:
The patent introduces adjustable lamp structures that allow individual lamps to change their illumination directions independently. This dynamic adjustment capability enables users to direct light where needed without moving their heads, improving operational ease while maintaining reasonable structural simplicity through modular adjustment mechanisms.
4Use of energy by moving object
If a small quantity of light is used for short range illumination, then energy consumption is reduced, but the conventional light emitter cannot adjust the amount of emitted light
Solution Approach 1:
The patent segments the illumination system into multiple independently controllable lamps with different light outputs. Users can activate only the necessary number and type of lamps based on the required illumination range, thereby adjusting energy consumption to match the actual lighting needs rather than operating at fixed high power.

AI summary
A light emitter to be attached to caps includes a case having several second lamps formed at a front surface thereof, a power switch attached to an outer surface of the case, a battery installed inside the case to provide power, a guide channel formed at a center of the case, a mounting clip formed at the outer surface of the case, a sub-body having a first lamp at a front surface thereof and being coupled to the guide channel, and a switch unit for controlling on/off operation of the first lamp. A user may move the sub-body back and forth to activate the first lamp, and may rotate the sub-body to alter the illumination angle of the first lamp.
