Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional laser level design is used, then device simplicity is maintained, but robustness and protection against impacts are insufficient
Solution Approach 1:
The patent applies beforehand cushioning by incorporating foam material between the battery pack and housing, and rubber bumpers on the base, to protect the laser level from impacts before they occur during transportation or use
Solution Approach 2:
The patent uses composite materials by combining foam material with rubber bumpers on the base, creating a multi-material protective system that enhances robustness while managing the complexity through functional integration
2Reliability
If protective structures are added to the housing, then protection against impacts is improved, but device complexity increases
Solution Approach 1:
The foam material positioned between the battery pack and housing provides beforehand cushioning to absorb impact forces before they reach sensitive internal components, improving reliability without adding complex active protection systems
Solution Approach 2:
The rubber bumpers on the base function as flexible protective elements that deform under impact to absorb energy, providing reliable protection while maintaining a relatively simple structural addition
3Duration of action of stationary object
If the laser level is designed for rugged use, then durability is improved, but ease of manufacture decreases
Solution Approach 1:
The foam material and rubber bumpers are pre-positioned during assembly to provide durability, using simple cushioning techniques that do not require complex manufacturing processes or specialized equipment
Solution Approach 2:
The protective elements are segmented into distinct components (foam material, rubber bumpers) that can be manufactured separately and assembled into the housing, improving ease of manufacture while maintaining durability
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 design enhances the laser level's durability, protects it from impacts and contaminants, ensures reliable operation in various environments, and provides extended battery life with secure charging solutions.
Implementation Method 1
The light source is supported by the housing and projects at least one beam of visible light onto a surface external to the laser level
Implementation Method 2
A degree of cushioning may be provided by a foam material positioned between the battery pack and the housing
Implementation Method 3
The base may include rubber bumpers on four corners of the base to help protect the laser level during transportation
