Solution Overview

Problem

Existing artificial accommodation systems continuously detect the need for accommodation without differentiating between necessary and unnecessary adjustments, leading to increased energy consumption and user discomfort.

Innovation Solution

A system that uses sensors to detect endogenous and environmental signals, converting them into control signals to trigger or interrupt the detection of accommodation needs, allowing for demand-oriented control of the accommodation system, thereby reducing energy consumption and improving user comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous detection of accommodation need is performed, then accommodation control is maintained, but energy consumption increases

Engineering Contradiction:
Improveaccommodation controlVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs accommodation detection periodically rather than continuously, using trigger signals to initiate detection cycles. The detection is activated only when specific conditions are met (e.g., change in viewing distance, blink detection), allowing the system to maintain adequate control while significantly reducing energy consumption during idle periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The detection frequency and activation state of the accommodation system are dynamically adjusted based on operational conditions. The system transitions between active detection states and low-power standby states, adapting its behavior to the user's actual needs rather than operating at constant high power consumption.

Inventive Principle:
Principle #15Dynamics

2Reliability

If continuous detection of accommodation need is performed, then accommodation control is maintained, but service life is reduced

Engineering Contradiction:
Improveaccommodation controlVSAvoidservice life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

By implementing periodic detection cycles triggered by specific events rather than continuous operation, the system extends the service life of battery-powered components and reduces wear on mechanical and electronic subsystems while maintaining adequate accommodation control functionality.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses preliminary detection of trigger conditions (such as blink patterns, head position changes, or environmental light changes) to anticipate when accommodation detection will be needed, allowing it to enter low-power states during predictable idle periods and thus extend overall service life.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If frequent accommodation detection is performed, then control precision is improved, but user comfort decreases

Engineering Contradiction:
Improvecontrol precisionVSAvoiduser comfort
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs detection at strategically timed intervals based on trigger events rather than at fixed high frequency, reducing the perceptibility of system operations to the user while maintaining sufficient precision for effective accommodation control.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system incorporates feedback mechanisms that monitor user response and environmental conditions to adjust detection frequency, performing more frequent checks when precision is critical and reducing frequency when the user is in stable viewing conditions, thereby balancing precision with comfort.

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to means for controlling the accommodation demand detection in an ophthalmic technical system (OTS) (6), comprising at least one sensor (1) for sensing an endogenous signal sequence or an environmental signal sequence and converting the signal sequence into measurement signals (3) and at least one detection unit (4) for converting the measurement signals (3) into a control signal (5), which influences the accommodation demand detection. The problem addressed by the invention is that of designing said means in such a way that significant energy savings of an artificial accommodation system (or OTS) are enabled without significant restriction of the user or that the user comfort is increased. This problem is solved in that the detection unit (4) has signal detection, which compares the measurement signals (3) with a reference signal bandwidth and produces the control signal (5) if a specified reference signal bandwidth overlaps with the measurement signals.
