Solution Overview

Problem

Modern salons face challenges in storing and transporting salon tools due to limited space and the need for compact solutions, particularly for digital tools like perming machines, which require efficient storage and transportation systems.

Innovation Solution

A modular trolley with a housing and removable drawers that includes a mounting structure for easy assembly and disassembly of perming machines, allowing for interchangeable storage and transportation of salon items, featuring screw holes, grooves, and ventilation for heat management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional salon trolley is used for storing products and tools, then storage capacity is limited, but the trolley structure remains fixed and cannot accommodate digital tools like perming machines

Engineering Contradiction:
ImproveadaptabilityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The trolley structure is divided into modular components including removable drawers and a perming machine mounting structure. The mounting structure includes separate holes in sidewalls and a rear wall that can independently receive screws or tabs, allowing flexible configuration. This segmentation enables the trolley to adapt between storing small salon items in drawers or mounting larger digital tools like perming machines.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting structure is designed with multiple holes positioned at different locations (sidewalls and rear wall) that can serve dual purposes: securing the perming machine when present, or allowing drawer installation when the machine is removed. The same structural features support both small item storage and large tool mounting, making the trolley universally applicable for different salon needs.

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

2Ease of operation

If a perming machine is mounted to the trolley, then storage and transportation of the machine is enabled, but the mounting process becomes complex and time-consuming

Engineering Contradiction:
Improveease of mountingVSAvoidmounting time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mounting holes and tabs are pre-positioned during manufacturing at optimal locations on the trolley structure. The drawers are designed with alignment features that guide their installation into the correct position. This preliminary preparation of mounting locations and alignment features significantly reduces the time and complexity of the actual mounting process, allowing stylists to quickly configure the trolley for perming machine storage.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If drawers are made removable from the housing, then flexibility in configuration is improved, but the structural integrity and stability of the housing may be compromised

Engineering Contradiction:
ImproveconfigurabilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The drawer mounting holes and the perming machine mounting holes are merged into the same structural features of the housing. The sidewalls and rear wall contain holes that can simultaneously or alternatively receive drawer fasteners or perming machine screws. This merging of mounting functions into unified structural elements maintains the housing's structural integrity while enabling both drawers and perming machines to be securely attached when needed.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A trolley for storing a plurality of salon items includes a housing having a plurality of walls, and a plurality of drawers slidably coupled to the housing and including at least one drawer of the plurality of drawers removably coupled to the housing. The trolley also includes a mounting structure arranged along at least one of the plurality of the walls and configured to facilitate a removable mounting of a perming machine to the housing. The mounting structure is disposed at a location corresponding to a location of the removable drawer inside the housing. The at least one removable drawer is removed from the housing to arrange and mount the perming machine inside the housing.
