Solution Overview

Problem

Current methods for changing the appearance of clutch bags are cumbersome and unsightly, as they require sewing or other complex processes to form resilient materials into three-dimensional shapes, and existing solutions are not suitable for convex surfaces like clutch bags, leading to undesirable aesthetics and limited utility.

Innovation Solution

A container section with a convex external surface and a removable resilient cover, retained by a retention frame that covers the edges, allowing the cover to be easily formed into a three-dimensional shape without sewing, and featuring a design where the retention frame covers the edges, providing a seamless aesthetic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resilient material is formed into three dimensional shape by cutting and stitching, then the cover can be securely attached to the container, but the process requires skill and time and creates visible seams that spoil aesthetics

Engineering Contradiction:
Improvesecure attachmentVSAvoidease of attachment
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The resilient cover is divided into multiple sections with adjoining edges that are angularly displaced when flat but become adjacent when the cover assumes its three-dimensional shape. This segmentation allows the cover to be attached without stitching while maintaining secure attachment through the retention frame.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention frame acts as an intermediary element between the resilient cover and the container. It includes guard portions that overlie the adjoining edges of the cover, securing it in place without requiring direct attachment of the edges themselves, thus eliminating visible seams.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If removable cover is used to change appearance, then customization is enabled, but the edges of the cover create unsightly gaps and seams on convex surfaces

Engineering Contradiction:
Improveappearance customizationVSAvoidunsightly seams and gaps
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The adjoining edges of the resilient cover are angularly displaced in the two-dimensional flat state but become adjacent in the three-dimensional formed state. This dimensional transformation allows the cover to conform to the convex surface of the container while eliminating visible seams and gaps.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The resilient cover is made from a flexible material that can be formed into a three-dimensional shape corresponding to the convex external surface of the container. This flexibility allows the cover to conform to the surface without creating unsightly gaps or seams.

Inventive Principle:
Principle #30Flexible shells and thin films

3Adaptability or versatility

If existing clutch bag design is used, then the bag is suitable for formal events, but the limited utility and lack of versatility restrict everyday use

Engineering Contradiction:
Improveoutfit compatibilityVSAvoideveryday usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The clutch bag design incorporates removable and interchangeable resilient covers that can be quickly changed to suit different outfits and occasions. This dynamic capability transforms the bag from a static formal accessory to a versatile item suitable for both formal events and everyday use.

Inventive Principle:
Principle #15Dynamics

AI summary

A container section comprising a convex external surface, a removable resilient cover for covering said external surface and a retention frame for removably retaining said resilient cover on said external surface, in which said resilient cover comprises at least one pair of edges which are displaced from one another when said resilient cover is arranged flat, and which are adjacent to one another when said resilient cover assumes a three dimensional shape corresponding to said external surface, and in which said retention frame comprises a guard portion which is configured such that it overlies said pair of edges when said retention frame retains said resilient cover on said external surface.
