Handle-Mounted Tool Force Feedback for Consistent Surface Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of handle-mounted tools in building construction often apply forces outside the optimal range, leading to inefficiencies and additional work, as they rely on 'feel' to gauge the engagement force, which can vary for different tools and operations.
Innovation Solution
A system with a force indicator that measures and compares the applied force to predetermined ranges, providing visual, audio, or vibration feedback to ensure the operator maintains the optimal engagement force for tools like corner rollers and paint applicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators rely on 'feel' to gauge engagement force, then the operation can be performed without additional equipment, but the engagement force consistency deteriorates and operators frequently apply force outside the optimal range
Solution Approach 1:
The patent applies feedback by providing real-time force magnitude indicators that give operators immediate information about the engagement force being applied. The indicator system continuously monitors and displays force levels, allowing operators to adjust their applied force to maintain optimal engagement, thereby improving force consistency while keeping the operation simple.
2Device complexity
If no force indication system is used, then the device complexity remains low, but the productivity deteriorates due to rework and additional work
Solution Approach 1:
The feedback principle is applied through a force indication system that provides real-time information to operators about engagement force levels. This allows operators to immediately correct force application errors, preventing rework and improving productivity without adding excessive complexity to the device.
3Device complexity
If operators apply force without force feedback, then the tool design remains simple, but the manufacturing precision deteriorates as operations fall outside predetermined force ranges
Solution Approach 1:
The patent implements feedback by providing force magnitude indicators that show operators whether they are applying force within the optimal predetermined range. This real-time information allows operators to adjust their technique to achieve precise force application, improving manufacturing precision while maintaining relatively simple tool design.

AI summary
A system and method for indicating a force applied to a tool is disclosed. The system can include a tool configured to engage a surface of a building; a handle configured to apply a first force to the tool, and a force indicator configured to indicate a representation of the first force to an operator. The method can include receiving a first force at a first tool, where a handle is configured to apply the first force to the first tool and cause the first tool to engage a surface of a building; and indicating, via a force indicator, a first indication to an operator when the first force is within a first predetermined range.
