Solution Overview

Problem

Existing dispensers face challenges in efficiently powering electronic components due to the complexity of connecting circuitry components with a power source, leading to increased costs and manufacturing complexity, especially in environments with limited AC/DC outlets.

Innovation Solution

A dispenser design where the printed circuit board is positioned on the front cover assembly, powered by power packs on the backplate, eliminating the need for additional wiring and simplifying electrical connections, with power packs optionally integrated into existing dispenser features like the overfill housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complicated system of connections and wires is used to connect circuitry components with a power source, then the dispenser can be powered reliably, but the cost and manufacturing complexity increase

Engineering Contradiction:
Improvepower connection reliabilityVSAvoidwiring complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the power source (power pack) from the main housing and places it in a separate, easily replaceable unit. This eliminates the need for complex internal wiring connections between the power source and circuit board, as the power pack contains all necessary power supply components in one self-contained unit that connects via simple interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a power pack as an intermediary component that mediates between the AC/DC power source and the circuit board. This power pack serves as a buffer that simplifies the connection system by consolidating power conversion and distribution functions into a single replaceable unit, eliminating the need for complex hardwired connections throughout the dispenser.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If additional sensors and control circuitry are added to the dispenser, then more functionalities are achieved, but the complexity of connecting circuitry components with a power source increases

Engineering Contradiction:
Improvedispenser functionalityVSAvoidcircuitry connection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power pack is designed as a universal power supply unit that can support multiple sensors and control circuitry functions. By consolidating all power supply, conversion, and distribution functions into this single multi-functional unit, the system can accommodate additional sensors and circuitry without increasing connection complexity, as all components draw power from the same standardized power pack interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the printed circuit board is positioned on the front cover assembly and powered by power packs on the backplate, then manufacturing is simplified and costs are reduced, but additional wiring may be required

Engineering Contradiction:
Improveassembly manufacturing easeVSAvoidelectrical connection complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent segments the dispenser into distinct functional modules: the front cover assembly containing the circuit board, and the backplate containing the power pack. This segmentation allows each module to be manufactured and tested independently, then assembled together with simple electrical connections, greatly simplifying the manufacturing process while minimizing wiring requirements through modular design.

Inventive Principle:
Principle #1Segmentation

AI summary

A dispenser for dispensing dispensable product is provided. The dispenser includes a housing having an interior volume so as to retain the dispensable product. The dispenser also includes a front cover assembly and a backplate that each form at least a portion of the housing. The front cover assembly includes a front plate having a first side and a second and opposite side. The first side forms the exterior of the dispenser and the second side faces the interior volume. A printed circuit board is disposed on the second side of the front plate. The back plate includes a first side and a second and opposite side facing the interior volume. One or more power packs are disposed on the second side of the backplate. The printed circuit board is powered by the one or more power packs when the front cover assembly is in a closed position.
