Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chiropractic adjustment instruments often lead to repetitive strain injuries in users due to manual pre-loading requirements, and they are often bulky and limited by power cables, which cause trip hazards and interfere with treatment.
Innovation Solution
A cordless chiropractic adjustment device powered by internal batteries, using a direct current motor to propel a thrust element with adjustable force and frequency, eliminating the need for manual pre-loading and power cables, and allowing for precise control of force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pre-loading is used to arm the device, then the device can deliver controlled thrust, but the user develops repetitive strain injuries
Solution Approach 1:
The patent replaces the manual mechanical pre-loading system with an electric motor-driven mechanism. The motor automatically arms the thrust element, eliminating the need for the chiropractor to manually compress strong springs, thereby preventing repetitive strain injuries while maintaining controlled thrust delivery.
Solution Approach 2:
The device performs self-arming through automatic motor-driven mechanisms. The system prepares and arms the thrust element without requiring manual intervention, making the device serve itself in the pre-loading function and removing the harmful manual operation component.
2Force
If alternating current solenoid systems are used, then strong spring force is countered, but lengthy cables cause trip hazards
Solution Approach 1:
The patent extracts and removes the lengthy power cable from the operational system by implementing a battery-powered design. The AC adapter is separated into a charging-only component, eliminating the cable hazard during actual device operation while maintaining the ability to counter strong spring forces through the motor system.
Solution Approach 2:
The patent introduces a battery as an intermediary energy storage device between the AC power source and the motor system. This intermediary allows the device to operate cordlessly by storing energy during charging and releasing it during operation, eliminating the need for a power cable during treatment.
3Ease of operation
If rechargeable battery packs are used, then cordless operation is achieved, but device complexity increases
Solution Approach 1:
The patent designs the battery compartment and AC adapter to serve multiple functions: the AC adapter both charges the battery and potentially provides direct power operation. This multi-functionality reduces the need for separate components and simplifies the overall power system architecture while maintaining cordless operation capability.

Data Source
AI summary
The invention provides a cordless chiropractic adjustment device including a thrust element (80) capable of impacting a body contact member (10), a resilient spring (314) arranged to bias the thrust element towards the body contact member, and a motor (120). The motor is arranged to move the thrust element between a variable primed configuration in which the thrust element is held out of contact with the body contact member, and a fired configuration in which the thrust element is propelled by the resilient spring into contact with the body contact member through a range of different impact forces. The motor is provided with direct current by one or more batteries (150), which may be rechargeable.
