Solution Overview

Problem

Existing stage lighting systems lack efficient remote control capabilities for lamp focus adjustments, requiring users to physically interact with consoles for precise focus settings, which can be cumbersome and limit accuracy.

Innovation Solution

A remote focus unit with wireless or network control allows for simplified, intuitive control of lamp focus settings through a PDA device with a user-friendly interface, enabling users to change focus presets and control lighting parameters from a distance, using a direct wireless connection or network interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If operators physically interact with consoles to control lamp focus, then direct control is achieved, but operator mobility is limited and focus adjustment efficiency decreases

Engineering Contradiction:
Improvefocus adjustment efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A wireless remote control device serves as an intermediary between the operator and the lighting console. The remote transmits control signals wirelessly to the console, which then adjusts the lamp focus. This mediator approach allows operators to control focus remotely without physically interacting with the console, improving efficiency while distributing system complexity across multiple components.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/physical interaction system with a wireless electronic communication system. Instead of operators physically manipulating console controls, wireless signals transmit focus adjustment commands from the remote device to the console, eliminating the need for direct physical contact and enabling remote operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If operators are tethered to the console for focus control, then direct monitoring is possible, but operator mobility and positioning flexibility are reduced

Engineering Contradiction:
Improveoperator positioning flexibilityVSAvoidvisual feedback quality
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent replaces physical tethering with wireless communication technology. The remote control device transmits and receives signals wirelessly through Bluetooth or WiFi, eliminating physical constraints on operator movement. Operators can freely position themselves while maintaining full control capability over lamp focus through the wireless interface.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If complex console interfaces are used for focus control, then precise adjustments are possible, but ease of use decreases

Engineering Contradiction:
Improvefocus precisionVSAvoidinterface usability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent extracts the essential focus control functionality from the complex console interface and implements it in a simplified remote control device. The remote contains only the necessary controls for focus adjustment, eliminating extraneous console features. This extraction maintains focus precision while dramatically improving ease of use by presenting a streamlined interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of requiring operators to adapt to the console's complex interface, the patent inverts the approach by designing a remote interface that adapts to operator needs. The remote control features an intuitive, simplified interface that naturally guides operators through focus adjustments, reversing the traditional model where the tool adapts to the user.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A remote-control device which allows remotely controlling parameters of a light via a console. The console actually does the controlling, but the remote-control device enables control of the light parameters by sending the information to the console. For example, the remote can be used to control preset values or to control other aspects of the console. The console may store presets associated with focus, and those presets can be changed from the remote.
