Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface protection devices, such as fender covers and whole-vehicle covers, suffer from deficiencies like exposure to dirty environments, pinching hazards, difficulty in deployment, and inadequate attachment to non-ferromagnetic surfaces, leading to scratches, abrasions, and inefficiencies in use.
Innovation Solution
A pad-based surface protection system comprising cushions with embedded magnets and removable textile covers, allowing for secure attachment to various surfaces using magnets, suction cups, or tape, with customizable materials and configurations for enhanced versatility and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fender covers are used to protect surfaces, then surface protection is provided, but the face side is exposed to dirty environments requiring frequent cleaning and non-woven materials may scratch the finish
Solution Approach 1:
The protective cover is divided into multiple fabric layers with different properties. The outer layer faces the dirty environment and can be removed for cleaning, while the inner layer contacts the protected surface with a smooth finish to prevent scratching. This segmentation allows each layer to perform its specific function optimally.
Solution Approach 2:
A magnet sheet is introduced as an intermediary component between the fabric cover and the protected surface. The magnet sheet provides reliable attachment through magnetic attraction while having a smooth surface that prevents scratching of the finished surface, mediating between the need for secure attachment and surface protection.
2Reliability
If whole-vehicle covers are used for protection, then water and dust protection is achieved, but they are large and difficult to deploy and stow
Solution Approach 1:
The protective system is segmented into multiple smaller pad units rather than one large cover. Each pad can be independently handled, deployed, and stored, making the system much easier to operate while maintaining comprehensive protection coverage when multiple pads are used together.
3Reliability
If pads use straps and hooks for attachment, then secure attachment is achieved, but straps are cumbersome and hooks pose pinching and scratching threats
Solution Approach 1:
The mechanical attachment system of straps and hooks is replaced with a magnetic attachment system. The magnet sheet provides secure attachment through magnetic attraction forces without requiring straps that can tangle or hooks that can pinch and scratch, eliminating harmful factors while maintaining attachment security.
4Reliability
If magnets are used for attachment, then secure attachment to ferromagnetic surfaces is achieved, but magnets attract loose metallic dust and shavings
Solution Approach 1:
A fabric layer is introduced as an intermediary between the magnet sheet and the protected surface. This fabric layer prevents direct contact between attracted metallic particles and the finished surface, allowing the magnets to maintain their attachment function while the fabric barrier prevents scratching from attracted debris.
5Ease of operation
If non-woven materials are used for covers, then easy cleaning is achieved, but scratching of refined finishes occurs due to trapped contaminants
Solution Approach 1:
The cover is segmented into an outer layer and an inner layer with different material properties. The outer layer can be made of easily cleanable material facing the dirty environment, while the inner layer has a smooth finish that prevents scratching when contacting the protected surface, allowing both cleaning ease and surface protection to be achieved.
