Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single wall switch controls all lighting apparatus, then the control system is simple, but individual lighting control is impossible and safety risks increase due to ladder requirements
Solution Approach 1:
The patent divides the centralized lighting control system into individual controllable units. Each lighting apparatus is equipped with its own photoreceptor element and switch mechanism, enabling independent control of each light fixture rather than controlling all lights through a single wall switch.
Solution Approach 2:
The patent introduces a laser pointer as an intermediary control device that communicates with photoreceptor elements on lighting apparatus. This optical intermediary allows users to control individual lights from a distance without physical contact or ladder usage, resolving the contradiction between operational ease and system complexity.
2Area of stationary object
If lighting apparatus are positioned at elevated locations, then space utilization is improved, but access for control and maintenance requires ladders posing safety risks
Solution Approach 1:
The patent uses a laser pointer as a remote intermediary device that transmits control signals optically to photoreceptor elements on elevated lighting apparatus. This eliminates the need for physical access via ladders, maintaining ceiling space utilization while removing safety hazards associated with ladder usage.
Solution Approach 2:
The patent replaces the mechanical control method (physical switch operation requiring ladder access) with an optical control system. The laser pointer transmits optical signals to photoreceptor elements, substituting mechanical interaction with optical communication to eliminate safety risks.
3Illumination intensity
If all lighting apparatus are illuminated simultaneously, then uniform illumination is achieved, but power consumption increases and energy efficiency decreases
Solution Approach 1:
The patent segments the lighting system into individually controllable units, each with its own switch and photoreceptor element. This allows selective illumination of specific areas by controlling individual lighting apparatus rather than illuminating all lights simultaneously, reducing power consumption while maintaining uniform illumination where needed.
Solution Approach 2:
The patent enables dynamic control of lighting apparatus, allowing users to adjust illumination levels and patterns based on actual needs. The laser pointer control system permits real-time switching of individual lights, creating dynamic illumination patterns that optimize energy usage while maintaining appropriate lighting levels.

Function Achieved in This Case
Enables safe and efficient management of lighting by allowing individual control of light emitters using a laser pointer, eliminating the need for ladders and improving power usage by allowing precise adjustment of lighting levels.
Implementation Method 1
The photoreceptor element receives a laser beam from a laser pointer, thus activating the control circuit to turn the switch on or off

AI summary
A lighting apparatus includes a power supply connection section, a light emitter, a switch, a control circuit, and a photoreceptor element. The power supply connection section is connected to a power supply. The light emitter emits light by power supplied from the power supply connection section. The switch is provided in a conductive path from the power supply connection section to the light emitter. The control circuit actuates the switch. The photoreceptor element is connected to the control circuit. The photoreceptor element receives a laser beam from a laser pointer to activate the control circuit so as to turn on or off the switch. The individual light emitters can be illuminated or extinguished simply by irradiating a laser beam from the laser pointer onto the switches. The lighting apparatus can be curtailed and restored to their initial conditions without removing and attaching the apparatus using a stepladder or ladder.
