Solution Overview

Problem

Existing devices for storing and dosing depilatory wax lack efficiency in providing a hygienic and precisely dosed amount, often requiring heating times and leading to excess wax usage and contamination risks.

Innovation Solution

A device with upper and lower containers, heating elements, and an outlet system with a controlled actuator to maintain depilatory wax in a flowable state, allowing for precise dosing and storage, while minimizing contamination and energy usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If depilatory wax is stored in a container ready for use, then rapid provision is ensured and waiting times are avoided, but the risk of contamination and excess wax usage increases

Engineering Contradiction:
Improvewaiting timeVSAvoidhygiene
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The device is divided into two separate containers: an upper container for storing solid depilatory wax and a lower container for holding melted wax ready for use. This segmentation allows the wax to be melted only when needed and enables precise dosing through the outlet cover mechanism, reducing both contamination risk and excess wax usage while maintaining rapid provision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outlet cover with actuator provides automatic dosing control, allowing the system to dispense the exact amount of wax needed without manual intervention. This self-service mechanism prevents excess wax usage and reduces contamination risk by limiting exposure of the melted wax to the environment.

Inventive Principle:
Principle #25Self-service

2Productivity

If depilatory wax is heated to flowable state for rapid provision, then application readiness is improved, but energy consumption and heating time increase

Engineering Contradiction:
Improveapplication readinessVSAvoidheating energy
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The heating element in the lower container is activated only when wax is needed, melting a small amount of wax from the upper container as required. This preliminary action on demand, rather than continuous heating, significantly reduces energy consumption while ensuring application readiness when needed.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses periodic heating cycles where the heating element is activated intermittently to maintain the wax in a flowable state in the lower container, rather than continuous heating. This periodic action reduces overall energy consumption while maintaining productivity.

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If outlet is left open for dosing, then dispensing is enabled, but contamination risk and heat loss increase

Engineering Contradiction:
ImprovedispensingVSAvoidhygiene
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The outlet cover is extracted as a separate controllable component that can be opened only when dosing is required and closed immediately afterward. This extraction allows the outlet to remain sealed most of the time, preventing contamination and heat loss, while enabling easy dispensing when needed through the actuator mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

4Loss of substance

If precise dosing is implemented with outlet cover, then excess wax is reduced, but device complexity increases

Engineering Contradiction:
Improvewax wasteVSAvoidoutlet control mechanism
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The outlet cover with actuator provides automatic dosing control that dispenses the exact amount of wax needed without requiring complex manual measurement or control systems. The self-service nature of the mechanism reduces wax waste through precise dosing while keeping the added complexity relatively simple and manageable.

Inventive Principle:
Principle #25Self-service

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

The device ensures rapid, hygienic, and precise dispensing of depilatory wax, reducing heating times, minimizing excess wax, and maintaining a consistent temperature to prevent contamination and burns.

Implementation Method 1

a first heating device provided in or on the first upper container for heating the melting product in the first upper container, a second heating device provided in or on the first lower container for heating the melting product in the first lower container

Methodology Applied
Scientific EffectHeating: Heating

Implementation Method 2

The depilatory wax is usually in a semi-solid or solid form at room temperature, i.e. in a non-flowable state, and must be heated to reach a flowable state

Methodology Applied
Scientific EffectMelting: Melting

Implementation Method 3

at least one actuator connected to the outlet cover and designed to move the outlet cover, by a translational movement substantially parallel to a plane of the outlet cover, into a first position in which the outlet cover completely closes the outlet

Methodology Applied
Scientific EffectTranslational movement:

AI summary

A device (1) for storing and/or dispensing a melt product comprises a first upper container (7a, 7b) for receiving the melt product, with a first heating device (8a, 8b) for heating the melt product in the first upper container, a first lower container (9a, 9b) provided below the first upper container (7a, 7b) for receiving the melt product from the first upper container, with a second heating device (10a, 10b) for heating the melt product in the first lower container, and an outlet (20) provided on the underside of the first lower container (9a, 9b) for dispensing the melt product from the first lower container.Furthermore, at least one outlet cover (21, 22) is provided at the outlet, which is essentially planar and is designed to close the outlet (20), and the device comprises at least one actuator (24, 25) which is connected to the outlet cover (21, 22) and is designed to bring the outlet cover into a first position, in which the outlet cover completely closes the outlet, and into a second position, in which the outlet cover releases the outlet, by means of a translational movement (B1, B2) essentially parallel to a plane of the outlet cover.
