Continuous Time Adjustment Method for Daylight Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The abrupt time changes associated with traditional Daylight Saving Time (DST) protocols disrupt sleep schedules and productivity, particularly affecting younger children and leading to increased industrial accidents and decreased work productivity.
Innovation Solution
Implementing a continuous time adjustment method by adding or removing 'leap seconds' or defining a 'social second' that varies from the standard scientific second, allowing for gradual adjustments over several months, thereby minimizing disruption while maintaining consistency with international time standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional DST protocols are implemented with abrupt time changes, then daylight hours are extended during summer months, but sleep schedules are disrupted and productivity decreases
Solution Approach 1:
The patent segments the one-hour time adjustment into multiple smaller adjustments distributed across several months. Instead of a single abrupt change, the time shift is divided into incremental adjustments (e.g., adding or removing seconds daily or weekly) that accumulate to achieve the full DST effect, thereby avoiding sudden disruptions to sleep and productivity
Solution Approach 2:
The patent implements dynamic time adjustment where the rate and magnitude of time change are continuously adapted over time. The adjustment process transitions from no time change to full DST offset gradually, allowing systems and human circadian rhythms to adapt dynamically rather than facing a static, abrupt change
2Duration of action of moving object
If traditional DST protocols are implemented with abrupt time changes, then daylight hours are extended during summer months, but sleep schedules are disrupted
Solution Approach 1:
The time adjustment is segmented into small, distributed increments rather than a single large change. By adding or removing time in small steps (e.g., seconds per day) over many days, the patent prevents sudden disruptions to sleep schedules while still achieving the desired extension of daylight hours
Solution Approach 2:
The patent applies cushioning by introducing gradual transitional adjustments before the full DST effect is achieved. These preliminary incremental changes act as a buffer that protects sleep schedules from abrupt disruption, allowing gradual adaptation before the complete time shift is implemented
3Duration of action of moving object
If traditional DST protocols are implemented with abrupt time changes, then daylight hours are extended, but industrial accidents increase
Solution Approach 1:
The patent segments the time adjustment into gradual increments distributed over time, preventing the sudden disruption that triggers increased industrial accidents. By spreading the adjustment across multiple small steps rather than one abrupt change, the system maintains operational safety while achieving extended daylight hours
4Productivity
If gradual time adjustment is implemented using leap seconds or social seconds, then disruption to sleep and productivity is minimized, but complexity of timekeeping systems increases
Solution Approach 1:
The patent introduces an intermediary layer (software time adjustment mechanism) that mediates between the standard scientific time and the adjusted social time. This intermediary handles the complex calculations of incremental adjustments, leap seconds, and variable second lengths, shielding users and standard systems from the complexity while enabling gradual time changes
5Ease of operation
If variable social seconds are used for gradual adjustment, then abrupt time changes are eliminated, but precision in time measurement varies
Solution Approach 1:
The patent applies local quality by maintaining different time precision characteristics for different purposes. Scientific time measurements retain their standard precision and uniform second length for scientific and technical applications, while social time uses variable seconds optimized for human convenience and gradual adjustment, allowing each domain to have its optimal time properties

AI summary
There is disclosed in one example a method of observing continuous daylight adjustment (CDA) time, including: commencing at a first transition date observing an annual spring-forward period including lengthened social seconds, wherein a lengthened social second is longer than a standard scientific second; commencing at a second transition date observing an annual fall-back period including shortened social seconds, wherein a shortened social second is shorter than a standard scientific second; and computing and electronically displaying in a human-readable format a current social time different from a current scientific time.
