Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If objects are attached to polymeric membranes using conventional methods, then attachment security is improved, but membrane damage and water leakage occur
Solution Approach 1:
A mounting plate serves as an intermediary component between the object and the polymeric membrane. The mounting plate distributes attachment forces across a larger area of the membrane, preventing concentrated stress points that would cause damage. The mounting plate includes a bonding surface that interfaces with the membrane through adhesive bonding, while providing attachment points for the object, thus mediating the connection without direct piercing or damage to the membrane.
Solution Approach 2:
The attachment system is segmented into distinct functional components: the mounting plate with bonding surface, the polymeric membrane, and the object to be attached. This segmentation allows each component to perform its specific function optimally - the mounting plate handles mechanical attachment, the membrane provides waterproofing, and the adhesive layer provides bonding, avoiding the need for the membrane to directly承受 attachment forces.
2Ease of operation
If piercing methods are used to attach objects to polymeric membranes, then attachment simplicity is improved, but waterproof integrity deteriorates
Solution Approach 1:
The mounting plate acts as a mediator that eliminates the need for piercing the membrane. Instead of directly attaching the object to the membrane through holes or punctures, the mounting plate bonds to the membrane surface and provides attachment points for the object, maintaining the membrane's continuous waterproof barrier while achieving secure attachment.
Solution Approach 2:
The mechanical piercing attachment system is replaced with an adhesive bonding system. Rather than using holes, screws, or mechanical fasteners that penetrate the membrane, the invention uses adhesive bonding between the mounting plate and membrane surface, substituting mechanical penetration with chemical/adhesive bonding to preserve waterproof integrity.
3Object-affected harmful factors
If adhesive bonding is used to attach mounting plates to polymeric membranes, then membrane integrity is improved, but bonding reliability deteriorates due to temperature fluctuations
Solution Approach 1:
The bonding system is designed to accommodate temperature parameter changes. The adhesive layer is selected to maintain bonding properties across the expected temperature range. The mounting plate and membrane materials are chosen with compatible thermal expansion coefficients to minimize stress from thermal cycling. The bonding surface area is optimized to distribute thermal stresses and maintain reliable bonding under varying temperature conditions.

AI summary
A mounting system and method to elastically attach an object to a support structure with an elastic membrane. The elastic membrane allows the object attached thereto to elastically extend in a direction away from the support structure as force is exerted on the object. The elastic membrane includes two surface areas, the first surface area extending peripherally along a perimeter a bottom surface of the elastic membrane and a remaining second surface area. The first surface area being thermally bonded to the support structure, while the second surface area remaining separable from the support structure.
