Display Frame Retention Using Housing Protrusions in Hand Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display assemblies in hand tools face challenges in accommodating additional electronics due to space constraints, particularly when incorporating brushless DC electric motors and display components, necessitating the use of fasteners that occupy valuable space.
Innovation Solution
A display assembly design that utilizes protrusions on the housing to couple the frame to the display housing, eliminating the need for fasteners and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners are used to retain the frame to the display housing, then the frame is securely retained, but space in the tool housing is consumed
Solution Approach 1:
The patent integrates the frame retention function directly into the display housing structure by incorporating protrusions that engage with the frame. This merging of the retention mechanism into the housing itself eliminates the need for separate fasteners, thereby securing the frame while conserving space in the tool housing.
Solution Approach 2:
The patent extracts the fastener component from the assembly by replacing it with integrated protrusions on the display housing. This removal of the separate fastener element eliminates the space that would have been required for fastener installation and retention, while maintaining the frame retention function through the protrusion-frame engagement.
2Adaptability or versatility
If additional electronics are added for brushless DC motors, then motor functionality is improved, but space constraints are exacerbated
Solution Approach 1:
The patent merges multiple functions into the display housing structure, including the frame retention function through integrated protrusions. This consolidation of functions into existing structural elements avoids the need for additional separate components that would consume space, thereby accommodating the electronics required for brushless DC motor functionality without exacerbating space constraints.
3Object-affected harmful factors
If the display assembly includes protective frames and fasteners, then display protection is improved, but device complexity increases
Solution Approach 1:
The patent combines the frame retention function with the display housing structure by integrating protrusions directly into the housing. This merging eliminates the need for separate fastener components, thereby reducing device complexity while maintaining display protection through the protective frame that engages with these integrated protrusions.
Solution Approach 2:
The patent extracts the fastener component from the display assembly by replacing it with integrated protrusions on the display housing. This removal reduces the number of parts and simplifies the assembly process, thereby reducing device complexity while maintaining the protective function of the frame through direct engagement with the housing protrusions.

AI summary
A display assembly for a tool having a housing. The display assembly has a display unit, a frame, a display housing, and buttons. The display housing has a protrusion that is received by an aperture of the frame adapted to receive the protrusion to couple the frame to the display housing. The display unit is disposed between the display housing and the frame. The buttons are disposed on the display housing.
