Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional foil applicators are ineffective at edges, seams, and transitions due to wide pressing edges, requiring additional tools to manage air bubbles and apply foil behind or below edges, such as window rubber, leading to reduced quality and increased risk of damage.

Innovation Solution

A foil applicator with an elongate handgrip and a triangular pressing edge at an angle, featuring a curved side forming a hook, allows for easy foil manipulation without additional tools, enabling the hook to pull back foil from edges and raise rubber edges for application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional foil applicator with a wide pressing edge is used, then it can apply foil to large surfaces, but it cannot effectively work at edges, seams, and transitions due to the wide pressing edge

Engineering Contradiction:

Improveeffectiveness at edges and transitionsVSAvoidneed for additional tools

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pressing edge is segmented into multiple functional zones: a main pressing surface for large areas and a separate hook element for edges and transitions. This segmentation allows each part to perform its specialized function effectively, resolving the contradiction between handling large surfaces and working at edges.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The foil applicator is designed with multi-functionality by integrating both a pressing edge for general application and a hook for edge manipulation into a single tool. This eliminates the need for separate tools while maintaining effectiveness at edges, seams, and transitions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If a conventional foil applicator is used, then it has a simple design, but it requires additional tools to pull back foil and manage air bubbles at edges

Engineering Contradiction:

Improvesimplicity of designVSAvoidfoil manipulation at edges

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The hook element is merged with the pressing edge structure, creating an integrated tool that combines foil application and edge manipulation capabilities. This merging maintains design simplicity while eliminating the need for separate tools, directly resolving the contradiction between simplicity and operational ease.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the pressing edge is made narrow to work at edges, then it can provide fine touch, but it cannot effectively press foil on large surfaces

Engineering Contradiction:

Improvefine touch at edgesVSAvoidefficiency on large surfaces

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The pressing edge is segmented into a main pressing surface with sufficient width for large surfaces and a separate hook element for fine edge work. This segmentation allows the tool to provide fine touch at edges through the hook while maintaining the capability to efficiently press foil on large surfaces through the main pressing surface.

Inventive Principle:

Principle #1Segmentation

4Manufacturing precision

If additional tools are used to manage foil at edges, then foil quality can be maintained, but it increases the risk of damage and reduces workflow continuity

Engineering Contradiction:

Improvefoil qualityVSAvoidworkflow interruptions

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The integrated design with the hook element allows continuous workflow by enabling edge manipulation and foil adjustment without putting down the tool or switching to another instrument. This continuity maintains foil quality while eliminating workflow interruptions and associated damage risks.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

The present invention relates to a foil applicator, such as a spatula (1), for applying foil, in particular self-adhesive foil, to a surface, for instance the bodywork of a car. It is the object according to the present invention to provide an improved foil applicator. For this purpose the handgrip (2) is elongate and the pressing edge (5) lies at an angle relative to the handgrip. The foil applicator further comprises at least one hook (7, 8). Using the hook adhered foil can be pulled back, for instance out of or from edges, seams and transitions, in the event air bubbles have been included in the foil, without having to pick up another tool, which would take some time and during which time the foil could adhere more fixedly to the surface and the foil could be damaged even more when—after another tool has been picked up—it must then be released at or from the edges, seams and transitions.
