Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching planks to walls, such as nail-based systems and conventional peel-and-stick adhesive systems, face issues like aesthetic concerns, adhesive waste, and instability on uneven surfaces, particularly in high humidity or temperature conditions.
Innovation Solution
The development of planks with strategically designed adhesive-receiving channels and plateaus on the back member, which guide the application of construction adhesive and provide flexibility for uneven surfaces, allowing for secure attachment without nails and minimizing adhesive waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If double-sided adhesive tape is used in a peel-and-stick system, then installation convenience is improved, but bond stability deteriorates over time
Solution Approach 1:
The patent changes the adhesive application parameters by using construction adhesive instead of tape adhesive, and modifies the wall surface parameters by adding receive channels. This combination maintains installation ease while significantly improving bond stability and long-term reliability of the plank attachment.
Solution Approach 2:
The receive channels act as an intermediary structure between the wall surface and the adhesive. These channels pre-position and contain the adhesive in optimal locations, mediating between the adhesive and wall to ensure stable bonding while maintaining ease of application.
2Reliability
If construction adhesive is applied liberally to ensure plank fastening, then attachment reliability is improved, but adhesive waste increases
Solution Approach 1:
The receive channels create localized zones of concentrated adhesive rather than diffuse application. Each channel acts as a local reservoir that precisely positions adhesive where needed, ensuring reliable attachment while minimizing waste by preventing excessive adhesive application.
Solution Approach 2:
The wall surface is segmented into multiple receive channels distributed across the plank back surface. This segmentation divides the adhesive application into discrete, controlled portions, allowing precise adhesive placement in each channel while reducing overall adhesive consumption compared to liberal continuous application.
3Adaptability or versatility
If the wall surface is not perfectly flat, then installation adaptability is improved, but adhesive bonding effectiveness deteriorates due to gaps
Solution Approach 1:
The receive channels add a vertical dimension to the adhesive application system. By creating depth variations in the wall surface through channels, the system can accommodate plank back surface irregularities while maintaining consistent adhesive contact and bonding effectiveness across uneven surfaces.
Solution Approach 2:
The receive channels pre-position adhesive in advance before plank installation. This beforehand preparation ensures that adhesive is already in optimal positions to compensate for surface irregularities, cushioning against the effects of uneven walls or plank backs and ensuring reliable bonding despite dimensional variations.

Implementation Method 1
The channels serve two purposes, to assist the end user in application of the adhesive and to provide a degree of flexibility in the plank
Implementation Method 2
The channels serve two purposes, to assist the end user in application of the adhesive and to provide a degree of flexibility in the plank to allow the plank to attach to an uneven wall

AI summary
A plank and plank system for covering a wall or other surface is provided. Each longitudinally extending plank comprises a generally planar front façade and a back member. The back member comprises multiple plateaus interspersed with channels. Each plateau provides a flat surface that will be adjacent to the wall/surface when the plank is installed and onto which, optionally, a strip of pressure sensitive adhesive tape may be applied. The channels or an allocation feature within the channels provide a predetermined location and predetermined holding capacity to regulate the location and amount of construction adhesive to be applied by a user. In an aspect of the invention, the channels also provide a degree of flexibility that allows the plank to adhere securely to the wall and that allows the depth of the plank to be greater than conventional wood wall covering panels.
