Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tool accessory holder is used to access various workpiece regions, then accessibility to workpiece regions is improved, but visibility of the workpiece region deteriorates
Solution Approach 1:
An LED light assembly is introduced as an intermediary element to provide illumination to the workpiece area. The light assembly includes an LED, circuit board, and lens that work together to illuminate the work region, solving the visibility problem created by using angled tool accessory holders.
2Illumination intensity
If the light assembly is integrated into the housing, then visibility is improved, but vibration damping requirements increase
Solution Approach 1:
A vibration damping member made of elastomeric material is positioned between the light assembly and the housing to cushion and absorb vibrations before they reach the light assembly and its electronic components. This protective measure is built into the structure in advance to prevent vibration-related damage.
Solution Approach 2:
The housing is constructed as a composite structure with a rigid outer housing and an inner elastomeric vibration damping member. This composite design combines the structural integrity of rigid materials with the vibration-absorbing properties of elastomeric materials to protect the light assembly.
3Ease of manufacture
If electronic components are exposed, then ease of manufacture is improved, but reliability deteriorates due to dust and debris
Solution Approach 1:
The circuit board and other electronic components are nested within the housing structure, specifically positioned within the cavity formed by the vibration damping member. This nesting arrangement naturally protects the components from dust and debris while maintaining ease of assembly through the modular design.
Solution Approach 2:
The elastomeric vibration damping member acts as a flexible protective shell that seals the cavity containing the electronic components. This flexible barrier prevents dust and debris from reaching the electronics while allowing for vibration isolation.
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 solution allows users to better see the workpiece, inhibits vibrations, and prevents battery drainage by automatically turning off the light, while keeping electronic components sealed and clean.
Implementation Method 1
The light may include a LED coupled to the circuit board
Implementation Method 2
The insert is configured to dampen vibrations between the input shaft and housing, and the light assembly. The insert may be composed of an elastomeric material
