Beverage Dispensing Heads with Self-Contained Lighting Modules
Solution Overview
Problem
Beverage dispensing machines with discrete post-mix heads lack illumination for the housing and working areas, and integrating lighting into these systems is challenging, especially when compared to multi-flavor post-mix systems.
Innovation Solution
Development of self-contained lighting modules that can be connected to the existing electrical circuit of discrete post-mix beverage dispensing heads, featuring a light guide and LED sources to illuminate the housing and nozzle area, allowing for simultaneous or sequential illumination of graphics and the dispensing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lighting modules are integrated into discrete post-mix beverage dispensing heads, then illumination of the housing and nozzle area is improved, but device complexity increases
Solution Approach 1:
The lighting module is designed to be self-contained with its own power source (battery) and control circuitry, allowing it to operate independently without requiring integration into the main dispensing system's electrical infrastructure. The module activates automatically when the dispensing head is removed from the docking station, eliminating the need for complex wiring modifications.
Solution Approach 2:
The lighting function is separated from the main dispensing system as a distinct, modular component. The lighting module can be independently installed, removed, and replaced without affecting the core dispensing mechanism, thereby adding illumination functionality while minimizing impact on system complexity.
2Ease of manufacture
If self-contained lighting modules are used, then ease of installation is improved, but use of energy increases
Solution Approach 1:
The lighting module operates in periodic cycles rather than continuously - it activates only when the dispensing head is removed from the docking station and deactivated when docked. This intermittent operation pattern reduces overall energy consumption while maintaining illumination availability during use.
Solution Approach 2:
The lighting module uses a rechargeable battery with limited cycle life as a disposable-like component. When the battery is depleted, the entire lighting module can be replaced as a single unit rather than troubleshooting individual components, simplifying maintenance while keeping energy costs manageable through standardized battery replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides effective illumination of the dispensing head's housing and nozzle area, enhancing visibility and usability, particularly when integrated into discrete post-mix systems, without requiring significant modifications to existing electrical setups.
Implementation Method 1
A lighting module disposed in the housing is configured to illuminate the front of the housing and the base of the housing when the switch is moved into the closed position

AI summary
A beverage dispensing head includes a housing having a front, a rear, and a base that extends between the front and the rear. A mixing nozzle is configured to dispense a flow of beverage via the base. A valve is configured to control the flow of beverage via the mixing nozzle, and a switch is movable into and between a closed position in which the valve opens the flow of beverage via the mixing nozzle and an open position in which the valve closes the flow of beverage via the mixing nozzle. A lighting module disposed in the housing is configured to illuminate the front of the housing and the base of the housing when the switch is moved into the closed position.
