Level with metal frame supporting protective outer body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional levels are prone to damage and contamination from materials like concrete, dirt, and dust due to their design, which limits their usability and lifespan in harsh environments.
Innovation Solution
The development of a level with a scratch-resistant window and a sealed, polymer-covered metal frame that prevents material entry and features a non-stick outer sleeve and asymmetrical cross-sectional profile for improved grip and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional level design is used, then the structure is simple and easy to manufacture, but the level is prone to damage and contamination from materials like concrete, dirt, and dust
Solution Approach 1:
The level combines a metal frame structure with a polymer outer body that has non-stick properties. This composite construction provides both the structural integrity of metal and the protective, contamination-resistant properties of polymer material, resolving the contradiction between durability and structural complexity.
Solution Approach 2:
The polymer outer body acts as a protective shell that covers and protects the internal metal frame from contact with harmful materials. This flexible protective layer prevents contamination while maintaining the structural framework, addressing the contradiction between reliability and device complexity.
2Adaptability or versatility
If the level is placed in harsh environments, then it can be used for demanding tasks, but it suffers from contamination and reduced lifespan
Solution Approach 1:
The polymer outer body with non-stick properties provides preliminary protection against contamination before harmful materials can adhere to or damage the level. This pre-established protective barrier prevents concrete, dirt, and dust from causing damage, enabling use in harsh environments while preserving lifespan.
Solution Approach 2:
The polymer shell serves as a protective film that shields the internal components from harsh environmental conditions. This outer layer allows the level to be used in demanding tasks while preventing contamination that would otherwise reduce its lifespan.
3Object-affected harmful factors
If a sealed design is implemented, then material entry is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The polymer outer body functions as a sealed protective shell that prevents material entry into the internal hollow area. This shell design achieves effective sealing while maintaining relative manufacturing simplicity through overmolding or attachment processes.

AI summary
A tool, such as a level, including one or more polymer/plastic body segment, protective cover and/or seal is provided. The covers discussed herein may limit or prevent dirt or construction materials, such as concrete, from entering into the level body. The cover may also be a non-stick material, such as a polymer outer sleeve, that limits the ability of dirt and construction material to adhere to the level. The level may also include scratch resistant vial windows.
