Cutting Machine Weighing Device Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines with weighing devices are prone to damage from flexible cables that connect the load cell to the display unit, affecting measurement accuracy due to mechanical stress and potential crushing.
Innovation Solution
A robust cutting machine design where the weighing device is slidably connected to the machine housing via a carrier device, with a display unit fixed to the weighing device, ensuring the cable connection remains constant, and incorporating a sealed slide bearing for mechanical stability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible cable is used to connect the load cell to the display unit, then the weighing device can be moved relative to the machine housing, but the cable can be damaged or pinched, affecting measurement accuracy
Solution Approach 1:
The patent replaces the flexible cable connection with a rigid cable routing through a guide channel. The cable is guided through a defined path in the machine housing, preventing it from being pinched or damaged during movement of the weighing device, thus substituting the vulnerable flexible connection with a protected rigid guidance system
Solution Approach 2:
The guide channel acts as an intermediary structure that mediates between the movable weighing device and the fixed machine housing. It provides a protected path for the cable, allowing movement while preventing direct contact between the cable and external crushing forces
2Measurement precision
If the display unit is rigidly connected to the weighing device, then the position relative to load cell remains constant, but the overall device complexity increases
Solution Approach 1:
The display unit is rigidly integrated with the weighing device housing, merging these two components into a single structural unit. This ensures the display unit moves together with the weighing device, maintaining constant relative position to the load cell without requiring additional complex positioning mechanisms
3Length of stationary object
If the load cell is positioned laterally next to the machine housing, then the overall height is reduced, but the mounting stability may be compromised
Solution Approach 1:
The load cell is mounted laterally on the end face of the machine housing instead of vertically, changing the mounting dimension from vertical to horizontal. This reduces the overall height of the machine while the load cell remains securely mounted through lateral support structures

AI summary
A cutting machine (1) for slicing slices from strand-shaped food products is proposed, including a weighing device (2). The cutting machine comprises a machine housing (11) which includes a motor-driven cutting blade (16) and a weighing device (2). The weighing device has a load plate (22) arranged in a storage area (13) for depositing the sliced portions. The load cell (21) is movable relative to the machine housing (11) together with the load plate (22), thus enabling a two-dimensional or three-dimensional placement pattern.
