Industrial Truck Fork Cable Groove for Protected Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connection methods for industrial truck forks, such as gluing or screwing, result in high manufacturing costs, long delivery times, storage issues, and difficulty in maintenance, while offering limited flexibility and inadequate mechanical protection.
Innovation Solution
A flexible cable holder system with a groove-shaped recess in the fork tine allows for tool-free attachment and easy replacement of cable connections, using a flexible cable holder that elastically fits into the groove, providing self-retention and protection against mechanical damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable connection is glued or screwed to the fork tine, then the cable connection is fixed to the fork, but manufacturing costs increase, delivery times lengthen, and maintenance becomes difficult
Solution Approach 1:
The cable holder is divided into a modular system with a receiving groove formed in the fork tine and a separate cable holder component that can be independently manufactured and then assembled. This segmentation allows the fork and cable holder to be produced separately and efficiently, then quickly combined through the insertion connection, resolving the contradiction between reliable fixation and ease of manufacture.
2Reliability
If cable connection is glued or screwed to the fork tine, then the cable connection is secured, but repair time increases and service complexity increases
Solution Approach 1:
The receiving groove is pre-formed in the fork tine during manufacturing, and the cable holder is designed with preliminary positioning features that guide insertion. This preliminary preparation enables quick repair operations where the cable holder can be rapidly removed and replaced without complex tools or procedures, resolving the contradiction between secure connection and ease of repair.
3Reliability
If cable connection is glued or screwed to the fork tine, then the cable is fixed in position, but design flexibility is reduced and cable protection is inadequate
Solution Approach 1:
The cable holder design serves multiple functions: it provides secure positioning of the cable through the receiving groove, enables easy removal and reinstallation for maintenance, offers design flexibility for different cable configurations, and provides mechanical protection for the cable. This multi-functional design resolves the contradiction between position stability and design flexibility.
