Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle bumper protection methods, such as vinyl wraps and parking sensors, are either costly, environmentally unfriendly, or offer limited protection against scratches during parking maneuvers.
Innovation Solution
A scratch protection device with a motor-driven roller system and linear actuators that deploy a low-friction, customizable anti-scratch material over the vehicle bumper, providing comprehensive protection and easy deployment/retraction, powered by the vehicle's battery or an independent rechargeable battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vinyl wrap is used to protect the bumper, then the bumper is protected from scratches, but the exterior appearance is affected and the process is expensive and environmentally unfriendly
Solution Approach 1:
The protective material is made dynamically deployable and retractable through a roller mechanism driven by a motor. The material can be extended when protection is needed and retracted when not needed, transforming a static protective covering into a dynamic system that adapts to usage requirements.
Solution Approach 2:
The bumper protection system is segmented into a deployable roller mechanism with motorized control, separating the protective function from the vehicle's permanent structure. This allows the protection system to be independently controlled and operated without affecting the vehicle's appearance when retracted.
2Reliability
If a protective film is applied to the bumper, then scratch protection is provided, but the process is expensive and toxic chemical emissions occur
Solution Approach 1:
The system employs sensors that automatically detect potential collision risks and trigger the deployment of protective material without human intervention. The motorized roller and control system enable the protection mechanism to serve itself by responding autonomously to environmental conditions.
Solution Approach 2:
The patent replaces chemical protective films with a mechanical protective system using a roller-driven material deployment mechanism. This substitution eliminates toxic chemical emissions associated with film application while providing equivalent or superior protection through a controllable mechanical system.
3Reliability
If parking sensors are used, then limited protection is provided, but they may not function correctly if scratched or dirty
Solution Approach 1:
The protective material is deployed in advance before actual contact occurs, creating a cushioning barrier between the bumper and potential obstacles. This preemptive protection prevents scratches to both the bumper and the protective material itself, ensuring continuous functionality.
Solution Approach 2:
The protective material acts as an intermediary layer between the bumper and external objects. This mediator absorbs impact and prevents direct contact between potentially harmful objects and the bumper surface, eliminating the vulnerability of exposed sensors.
4Ease of operation
If a motor-driven roller system with linear actuators is used to deploy protective material, then comprehensive protection and easy deployment are achieved, but device complexity increases
Solution Approach 1:
The motor-driven roller system serves multiple functions: it deploys the protective material, retracts it, and can be controlled through various input methods (manual, automatic sensor-triggered, or remote). This multi-functionality justifies the increased complexity by providing versatile operation modes.
Solution Approach 2:
The system incorporates sensors that provide feedback about potential collision risks, triggering automatic deployment of the protective material. This feedback mechanism enables automatic operation, reducing the complexity burden on the user while maintaining comprehensive protection capabilities.
