Innovation Solution
A hand-held cable tie tool with a pistol-shaped design, featuring a trigger mechanism, tension mechanism, locking mechanism, cut-off mechanism, reel magazine assembly, feeder guide mechanism, and locking heads magazine assembly, all operated without the need for a power source, allowing for efficient tensioning and cutting of cable ties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If electric or pneumatic components are used in cable tie tools, then automation and power are improved, but device complexity, weight, and cost increase
Solution Approach 1:
The patent replaces electric and pneumatic systems with a purely mechanical operation system. The tool uses manual trigger activation that directly operates the cutting blade and tensioning mechanism through mechanical linkages, eliminating motors, batteries, and power transmission components while maintaining full functionality.
Solution Approach 2:
The cable tie tool is designed to be self-contained and manually operated, where the user's direct mechanical input through the trigger simultaneously activates both the cutting and tensioning functions. The tool serves itself without external power sources, reducing complexity while preserving automation of the core functions.
2Power
If electric or pneumatic components are used in cable tie tools, then power and automation are improved, but weight and portability worsen
Solution Approach 1:
The patent eliminates electric motors, batteries, and pneumatic systems that contribute significant weight. Instead, it employs a lightweight mechanical trigger system that directly actuates the cutting blade and tensioning mechanism, reducing overall tool weight while maintaining sufficient power for cable tie installation.
3Extent of automation
If electric or pneumatic components are used in cable tie tools, then automation is improved, but manufacturing cost and reliability worsen
Solution Approach 1:
The patent replaces expensive electric and pneumatic components with simple, manufacturable mechanical parts. The trigger-activated system uses basic mechanical elements like levers, blades, and springs that are inexpensive to manufacture and assemble, reducing overall tool cost while maintaining automated cutting and tensioning functions.
Solution Approach 2:
The tool employs simple, replaceable mechanical components such as the cutting blade and tensioning elements that can be easily manufactured at low cost and replaced if needed, rather than using expensive electric components that require complex maintenance and replacement procedures.
4Extent of automation
If electric or pneumatic components are used in cable tie tools, then automation is improved, but reliability worsens due to wear and failure
Solution Approach 1:
The patent eliminates electric motors, electronic controls, and pneumatic systems that are prone to failure from wear, electrical breakdown, and component degradation. The purely mechanical trigger system with direct actuation has fewer failure points and no electronic or power transmission components that can wear out, significantly improving reliability.
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 tool provides precise tensioning and cutting of cable ties with a simplified design, reducing manufacturing costs and minimizing the risk of failure, while maintaining operational efficiency.
Implementation Method 1
provide for a spring-biased rotation of said at least one cable strap reel about a cable strap reel center axis, wherein said spring-biased rotation is directed so as to wind up a cable tie strap coiled up onto said cable strap reel
Implementation Method 2
a tension mechanism, comprising a pawl link provided slidably reciprocatingly within said barrel portion along said longitudinal axis and operably coupled to said trigger mechanism, configured to grippingly engage the cable tie and apply tension to the tie tail
Implementation Method 3
The tie tail section is usually provided with teeth that engage with a pawl provided in the tie head and forming a ratchet so that, as the free end of the tie tail is pulled, the cable tie tightens and does not come undone
