Integrated automated analysis and repair

Abstract

An integrated highly automated analysis system employs a technician terminal for displaying a plurality of inspection screens, and for entering inspection results. The system generates an inspection report after the inspection results have been input. A point-of-sale terminal is coupled to the technician terminal, and the system further generates a cost estimate report in response to the generation of the inspection report and also generates an invoice report. The system includes a plurality of databases, including an inspection guideline database, a specifications database (containing specifications), a customer / inspection database (containing prior inspection records), and a parts catalog database (containing part numbers and part costs).

Problems solved by technology

The servicing of complex systems, for example, internal combustion engine automobiles, has become extremely complicated and, to some extent, virtually impossible for some persons to perform.

This problem extends to many mechanical and electrical systems as well as other systems, because of the complexity of these modern systems, the inadequacy of and rapid changes in available specifications and in some cases changes in regulatory requirements applicable to the systems.

Further, the capability of some diagnostic equipment used in diagnosing and servicing some systems has not kept pace with changes in the systems themselves.

Added to these complications is a growing scarcity of personnel trained in servicing such complicated systems.

For example, whereas it has been possible to service many vehicles with internal combustion engines by checking the condition of ignition parts, carburetor adjustments, or electrical systems, and replacing some or all parts, the newer vehicles have engines that do not have the older conventional ignition parts, the fuel supply is not easily adjusted, and the electrical system is sometimes separately controlled by its own built-in computer.

Some governmental regulatory agencies prohibit some adjustments to critical parts, or have established operating conditions for vehicle engines that require adjustments to an engine's operation that can only be accomplished with special test equipment.

Personnel that service systems such as vehicles also may contribute to servicing problems.

Often because the environment of a repair shop, the environment on a customer's site, or the environment in on an assembly line is quite noisy and / or otherwise distracting, and because the technicians working therein are under a great deal of pressure to quickly inspect and diagnose the systems on which they are working, important diagnostic steps may be skipped or incorrectly carried out.

This can result in needed repairs being overlooked, resulting in potentially dangerous conditions.

This is of particular concern when critical safety systems are involved, such as a vehicle's braking system or suspension, but is also of concern when a problem is not correctly diagnosed and repaired the first time a system is serviced because this leads to customer irritation and possibly loss of business.

Other systems, such as the exhaust system or the air conditioning system in an automobile, if not inspected properly, can require unscheduled maintenance or repair.

The dissemination of original system specifications, changes to such specifications, and other pertinent information relating to specific systems has also become problematic.

It is difficult to get the latest information to the system owner and to get the latest information to the system service agency.

It may also be difficult to get the person to whom the information is sent to read and apply the information to the diagnostic and servicing function.

Both paper manuals and microfilm systems require updating by physical replacement of outdated information and therefore have the problem of being dependent, to some extent, upon the interest and motivation of the receiver of the information.

Furthermore, it is not uncommon for errors to occur in the updating of paper manuals or microfilm systems, resulting in outdated or missing information.

Some engine analyzers merely measure existing conditions in a vehicle and are unable to compare the measured conditions to a reference standard that defines what the measured condition should be.

This discretion, and the desire on the part of some service advisors to increase the cost of vehicle service (and therefore their profits) by characterizing some repairs as required when they are in fact merely suggested, leads to discomfort on the part of the customer, which problematically breeds ill will and dissatisfaction.

Unfortunately, this problem exists outside the vehicle field as well.

There is a great deal of discretion on the part of the service advisor in generating the estimate, which results in under and over estimation of costs.

If the costs are under estimated, state law may prohibit the repair shop from charging the customer a correct amount.

If the costs are over estimated, the customer may be subject to over charging.

The problem of over estimating and under estimating may be compounded due to miscommunications between the technician or mechanic performing the vehicle diagnosis and the person who prepares the estimate.

Such hand-prepared reports are subject to numerous errors, both in entering the information and in interpreting the entered information.

Further, as with the problems of customer discomfort, ill will, and dissatisfaction, this problem exists outside the vehicle field as well.

Unfortunately, manually prepared invoices and other reports are error prone and consume significant amounts of time for those preparing such invoices and reports.
