3D Sticker with Segmented Adhesive and Rigid Thermoformable Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional thermoformed structures for promotional and aesthetic purposes are limited by their flexibility, which restricts their ability to maintain shape and adhere securely to surfaces, especially in outdoor environments and when repositioned, lacking support and integration with electronics.
Innovation Solution
A three-dimensional sticker with a rigid thermoformable plastic layer, a flexible ink layer, and a multi-layer adhesive system that includes both permanent and repositionable adhesives, allowing the sticker to retain its shape and adhere securely to various surfaces while enabling integration of electronics like lights with wireless remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible material is used for the banner, then it can be rolled up for storage or transport, but it must be anchored to the display site by grommets and rope or cord to prevent fluttering in the wind
Solution Approach 1:
The banner is divided into a base sheet portion and a raised three-dimensional portion, with the adhesive layer specifically positioned on the base sheet portion to provide secure attachment while allowing the raised portion to maintain its promotional display function
Solution Approach 2:
An adhesive layer is introduced as an intermediary between the banner and the display surface, replacing the need for mechanical anchoring systems like grommets and ropes, thereby simplifying the attachment method while maintaining security
2Ease of operation
If adhesive is applied only on the flat portion of the label, then the label can be applied to containers, but there is no support to help the label maintain its shape when peeled away from the container
Solution Approach 1:
The label is segmented into a flat base sheet portion and a raised three-dimensional portion, with the adhesive layer confined to the base sheet portion. This segmentation allows the raised portion to maintain its shape independently while the base sheet provides adhesive support
Solution Approach 2:
The adhesive layer is locally applied only to the base sheet portion rather than the entire label surface. This local quality approach provides sufficient attachment support while preventing adhesive from compromising the three-dimensional structure of the raised portion
3Stability of the object's composition
If a rigid material is used for the sticker, then it can maintain its three-dimensional shape and provide structural support, but it cannot be repositioned or reused
Solution Approach 1:
The adhesive layer uses repositionable adhesive with adjustable bonding parameters that allow the sticker to be attached securely, repositioned, and reused while the rigid base sheet maintains its three-dimensional shape stability throughout these operations
4Device complexity
If the banner material is made more permanent and rigid, then it would not need grommets and rope or cord for attachment, but it would lose the ability to be rolled up for storage or transport
Solution Approach 1:
The sticker is segmented into a rigid base sheet portion that provides structural support and shape stability, and a flat base sheet portion with adhesive that enables secure attachment to surfaces, eliminating the need for additional anchoring components while maintaining storability

AI summary
A three-dimensional sticker is disclosed that includes a body. The body has the following components: a main sheet constructed from a thermoformable plastic layer, and a flexible/stretchable ink layer adhered the main sheet. Additionally, the body may employ an adhesive layer comprising a repositionable adhesive adhered to the main sheet and a thermoformable release liner detachably adhered to the adhesive layer. A thermoformable foam layer may reside between the main sheet and the removable adhesive layer. The body is thermoformed into a three-dimensional shape with an anchor region and an elevated region. The anchor region is substantially planar and defines an anchor plane, and the elevated region is outside of the anchor plane. The adhesive layer and release liner may be present in the anchor region and elevated region.
