Reversible Punch Down Tool Bit Holder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing punch down tools are bulky, limited in functionality, and require technicians to carry multiple tools, making them cumbersome and costly to carry, due to their large size and specific design that does not accommodate reversible screwdriver bits effectively.
Innovation Solution
A hand tool with a reversible tool bit holder that integrates a ⅜ths hex driver and a standardized reversible punch down insert, using a circular spring clip with a reduced thickness and optimized dimensions to fit within a standard screwdriver handle, allowing for both punch down and screwdriver functions without additional spacers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standardized reversible punch down insert with 110 end and 66 end is used, then the tool can perform punch down operations on different cable and connector types, but the tool becomes bulky and unwieldy due to the large diameter required to accommodate the insert and circular spring clip
Solution Approach 1:
The patent combines a reversible punch down insert with a reversible bit holder into a single integrated tool. The punch down insert is mounted on one end of the bit holder, allowing the tool to perform both punch down operations and screwdriver operations with a single device, thereby reducing the number of separate tools needed and decreasing overall tool volume.
Solution Approach 2:
The tool is designed with multi-functionality by incorporating both a reversible punch down insert (supporting 110 and 66 connector types) and a reversible bit holder (supporting various screwdriver bits). This universal design allows a single tool to replace multiple specialized tools, addressing the versatility requirement while managing tool size through integration.
2Ease of operation
If a circular spring clip is used to secure the reversible punch down insert, then the insert can be removably secured to the shaft, but the tool requires a large diameter handle to house the shaft and spring clip mechanism
Solution Approach 1:
The reversible punch down insert is nested within the reversible bit holder structure. The insert fits into a recess in the bit holder, and the entire assembly is contained within the handle volume. This nesting arrangement allows the spring clip mechanism to be compact and integrated, reducing the overall handle diameter compared to having separate components.
3Reliability
If technicians carry separate punch down tools and screwdrivers, then each tool can be optimized for its specific function, but the overall number of tools increases making it cumbersome and costly to carry
Solution Approach 1:
The patent merges the functions of a punch down tool and a screwdriver into a single integrated device. The reversible punch down insert provides punch down functionality while the reversible bit holder provides screwdriver functionality, allowing technicians to carry one tool instead of two separate tools, thereby reducing complexity and portability burden.
Solution Approach 2:
The tool achieves universality by incorporating multiple functions (punch down operations with 110/66 connectors and screwdriver operations with various bits) into a single device. This multi-functional design reduces the number of separate tools needed while maintaining function-specific optimization through dedicated components for each operation type.
