Safety Brake Light Module Pulsing Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular safety brake lights often operate with a constant illumination pattern, failing to provide dynamic alerts to following drivers about braking events, especially when braking is applied in short bursts or without immediate deceleration.
Innovation Solution
A safety brake light module that includes a voltage regulation circuit, a controller, and a power circuit to generate illumination patterns with pulsing and constant portions based on the duration between braking events, using processing instructions to initiate the light signal responsive to braking and deceleration events, even in the absence of brake application, to provide enhanced visual alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a constant illumination pattern is used for safety brake lights, then the device complexity is reduced, but the ability to provide dynamic alerts and convey braking status clearly deteriorates
Solution Approach 1:
The patent applies periodic action by implementing pulsing illumination patterns that alternate between on and off states. The controller causes the safety brake light to pulse at specific intervals during braking events, creating a dynamic visual alert that captures following drivers' attention more effectively than constant illumination while maintaining manageable system complexity through standardized pulse patterns.
Solution Approach 2:
The patent implements dynamics by transitioning from static constant illumination to dynamic variable illumination patterns. The system adjusts the illumination state based on detected braking events, using motion sensors or brake signal inputs to trigger appropriate pulsing sequences. This dynamic behavior enables the light to convey different braking statuses (initiation, release, prolonged application) through distinct temporal patterns.
2Reliability
If the safety brake light provides dynamic illumination patterns responsive to braking events, then the alert effectiveness is improved, but the energy consumption increases
Solution Approach 1:
The patent reduces energy consumption through periodic action by using pulsing patterns instead of continuous illumination. The brake light activates in rhythmic on-off cycles during braking events, maintaining alert effectiveness through the attention-grabbing nature of pulsing while significantly reducing the average power draw compared to sustained constant illumination. The duty cycle of the pulses is optimized to balance visibility with energy conservation.
3Loss of information
If the safety brake light uses pulsing illumination patterns, then the attention-grabbing capability is improved, but the illumination consistency deteriorates
Solution Approach 1:
The patent employs periodic action with carefully controlled pulse durations and intervals to ensure that the pulsing pattern remains recognizable as a coherent braking signal. The illumination stability is maintained through consistent timing parameters defined in the controller, ensuring that each pulse sequence follows a predictable pattern that following drivers can interpret reliably, even though the instantaneous illumination level varies.
