Battery Pack Tether Receiver with Quick Attachment Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power tool batteries often lack adequate locations for tether attachment due to vent or drainage holes and being enveloped by tools, posing challenges for secure tethering, especially when working at heights, which can lead to safety issues and non-compliance with regulations.
Innovation Solution
The development of power tool batteries with built-in tether receivers and retrofit sleeve systems that allow for secure tether attachment without interfering with vent holes or tool engagement, including quick-release mechanisms for easy battery exchange and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether receiver is added to the battery housing, then safety and compliance with regulations are improved, but the device complexity increases
Solution Approach 1:
The tether receiver is integrated into the existing battery housing structure, allowing the same component to serve both as structural housing and as a tether attachment point. This multi-functional approach adds safety capability without proportionally increasing device complexity
Solution Approach 2:
The tether receiver features a nested structure with an outer housing and an inner receptacle that receives the tether. The tether attachment mechanism is nested within the receiver structure, allowing compact integration that minimizes additional space and complexity
2Temperature
If vent holes are provided in the battery housing, then thermal management is improved, but tether attachment locations are reduced
Solution Approach 1:
The tether receiver is positioned at a specific location on the battery housing that is distinct from the vent hole locations. This localized placement ensures that the tether attachment function does not interfere with the thermal management function, allowing both features to coexist without compromising either

AI summary
A battery tether system for tethering a power tool battery is provided. The battery may include a tether receiver as an integral component of the battery or the battery may be retrofit with a sleeve or bumper including a tether receiver. The sleeve may include a clasp to overlay the retrofit battery and ensure that the tether receptacle remains coupled to the battery. The tether receiver may connect to the tool receiver and provide an electrical connection to the tool and a tether receiver for the battery. The battery system may include tether keys configured to be inserted into a slot and slide into a locking pocket of the sleeve or bumper.
