Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Pre-filled user input fields on websites are vulnerable to accidental overwrites, leading to loss of data and inconvenience for users, as they are unprotected and editable by default.

Innovation Solution

A computer-implemented method that detects a mouseover event to toggle the state of pre-filled input fields between locked and unlocked, preventing accidental changes by write-protecting the fields when in a locked state, allowing users to intentionally change the state with specific user commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pre-filled input fields are left editable by default, then users can easily modify their information, but the fields become vulnerable to accidental overwrites and data loss

Engineering Contradiction:

Improveease of editing input fieldsVSAvoidprotection from accidental overwrites

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements a dynamic state change mechanism where input fields transition between locked and unlocked states based on user interaction. When a user hovers over a pre-filled field, the field becomes unlocked and editable; when the user moves away, it automatically locks again. This dynamic behavior allows the system to adapt its protection level based on the user's immediate intent, resolving the contradiction between ease of editing and protection from accidental overwrites.

Inventive Principle:

Principle #15Dynamics

2Reliability

If pre-filled input fields are locked by default, then accidental overwrites are prevented, but users cannot easily edit their information when needed

Engineering Contradiction:

Improveprotection from accidental overwritesVSAvoidease of editing input fields

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically transitions from a locked state to an unlocked state upon detecting user hover over the input field. This temporary unlocking allows users to edit information when needed, while the automatic re-locking maintains protection when the user is not actively interacting with the field. This resolves the contradiction by making the field accessible when needed but protected during idle periods.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the editability parameter of the input field based on user interaction state. The field's editability parameter is set to false (locked) by default for pre-filled fields, then changed to true (unlocked) when a user hovers over it, and reverted to false when the user moves away. This parameter change mechanism allows the system to balance protection and editability dynamically.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If users must manually unlock each field to edit, then data protection is maintained, but the user experience becomes cumbersome and time-consuming

Engineering Contradiction:

Improvedata protectionVSAvoidtime to edit fields

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system automatically detects user intent through hover detection and self-manages the unlocking process without requiring explicit user commands. When a user hovers over a locked input field, the system automatically unlocks it, allowing immediate editing. This eliminates the need for users to spend time searching for or executing unlock commands, resolving the contradiction between data protection and editing efficiency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs the unlocking action in advance, before the user actually needs to type in the field. By detecting the hover event and unlocking the field proactively, the system prepares the field for immediate editing, saving the user the time that would otherwise be spent on manual unlocking operations.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If the system adds lock state detection and toggling functionality, then protection from accidental overwrites is achieved, but the device complexity increases

Engineering Contradiction:

Improveprotection from accidental overwritesVSAvoidcomplexity of input field management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism (hover detection) that mediates between the user and the input field's editability state. This intermediary triggers the state transition automatically, simplifying the user interface while maintaining the necessary protection logic. The complexity is managed by using a well-understood interaction pattern (hover) rather than requiring users to learn new commands or interface elements.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A computer implemented method and computer program product for protecting a pre-filled user input field on a returned webpage from an accidental overwrite. The method identifies the pre-filled input field by detecting a mouseover. In response to a user command to change the state of the pre-filled input field, the method changes an initially unlocked pre-filled input field to a locked state or changes an initially locked pre-filled input field to an unlocked state.
