Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproofing methods for buildings during storms often leave strong adhesive residues or damage building surfaces when removed, posing challenges for easy and residue-free removal.
Innovation Solution
A temporary waterproofing system utilizing a repositionable, double-sided nano tape with sufficient adhesive strength to last at least 14 days and minimal residue left when removed within 7 days, ensuring easy removal without surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional waterproofing materials (sandbags, tapes, caulking, spray coatings, foams) are applied to protect buildings from water damage, then waterproofing effectiveness is improved, but removal difficulty and surface damage increase
Solution Approach 1:
The patent applies parameter changes by modifying the adhesive properties of the tape to achieve repositionability. The adhesive is formulated to provide initial strong bonding for waterproofing while allowing controlled removal and repositioning without leaving residue or damaging surfaces. This resolves the contradiction by changing the adhesive parameters to balance both waterproofing effectiveness and removal ease.
Solution Approach 2:
The patent implements dynamics through the time-dependent behavior of the adhesive. The adhesive exhibits dynamic characteristics where it provides strong initial adhesion when first applied, maintains bonding during the waterproofing period, but allows controlled removal after the storm event. This dynamic behavior enables the tape to fulfill both waterproofing and easy removal requirements.
2Reliability
If waterproofing materials are applied with strong adhesive strength to ensure durability, then waterproofing reliability is improved, but adhesive residue and surface damage increase upon removal
Solution Approach 1:
The patent resolves this contradiction by changing the adhesive parameters to achieve a balanced performance profile. The adhesive is formulated with specific properties that provide sufficient bonding strength for waterproofing while enabling clean removal. The repositionable adhesive technology allows the tape to maintain strong adhesion during use but release cleanly without leaving undesirable deposits on building surfaces.
Solution Approach 2:
The patent applies the disposable principle by designing a single-use waterproofing tape that performs its function effectively during the storm event and then can be removed and discarded. The tape is optimized for short-term use (during and immediately after the storm) rather than permanent installation, allowing it to be replaced after each use without accumulating residue or damaging surfaces.
3Duration of action of stationary object
If waterproofing tape is designed to adhere strongly for long duration (minimum 14 days), then waterproofing durability is improved, but removal within short time (within 7 days) becomes difficult
Solution Approach 1:
The patent implements dynamics through the time-dependent adhesive behavior that allows flexible removal timing. The repositionable adhesive is formulated to provide consistent bonding over an extended period (at least 14 days) while simultaneously allowing removal at any point within the first 7 days if needed. This dynamic adhesive profile provides both long-term durability and short-term flexibility.
Solution Approach 2:
The patent resolves this timing contradiction by changing the adhesive parameters to create a non-linear adhesion profile. The adhesive provides strong initial bonding that maintains waterproofing effectiveness over long periods, but includes controlled release properties that enable easy removal within the first week if weather conditions change or other needs arise.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nano tape effectively reduces water ingress into buildings during storms while ensuring easy and residue-free removal, maintaining the integrity of the building surfaces.
Implementation Method 1
having sufficient adhesive strength to adhere to said building for minimum of 14 days
Implementation Method 2
being sufficiently waterproof to reduce the ingress of water into the building when the tape is exposed to water

AI summary
A method to provide temporary waterproofing for buildings utilizes a waterproofing system comprising a repositionable adhesive tape. When the waterproofing system is applied to the building, then removed within 5 days, little or no adhesive residue remains on the building and no damage occurs. In an embodiment, the waterproof system includes additional protection.
